SUMMARY:Physics and Engineering Physics Colloquium
DESCRIPTION:Johannes Flick\, Ph.D.\, assistant professor\, Department of Physics\, City College of New York\, will present\, “First-Principle Approaches to Strong Light-Matter Coupling in Molecular and Extended Systems.” \nIn recent years\, research at the interface of material science\, chemistry\, and quantum optics has surged and now offers new possibilities to study light-matter interactions. The combination of theoretical concepts from these fields presents an opportunity to create a predictive theoretical and computational approach from first principles that describes the correlated dynamics of electrons\, nuclei\, and the electromagnetic field on the same quantized footing. \nIn this talk\, Flick will discuss how density-functional theory can be generalized to quantum-electrodynamical density-functional theory (QEDFT) and show how new exchange-correlation potentials arise. We discuss the linear-response theory for QEDFT to access excited state properties of such systems\, the emerging ab initio lifetimes\, and the incorporation of losses. By considering electrons\, nuclei\, and photons on the same quantized footing\, we find polaritonically induced vibrational mode mixing\, cavity-modulated molecular motion of molecules in optical cavities\, as well as new light-matter correlated observables for a new type of spectroscopy. Further\, we use this novel framework to study how chemical reactivity is altered in this regime\, by studying the modification of potential-energy surfaces under strong light-matter coupling. Beyond molecular systems\, we will discuss how strong light-matter coupling can be used to make nonlinear phonon processes more efficient and discuss first principle methods to characterize novel single-photon emitters.

SUMMARY:Physics & Engineering Physics Colloquium
DESCRIPTION:Dennis Marks\, Ph.D.\, professor emeritus\, Department of Physics\, Astronomy\, Geosciences and Engineering Technology at Valdosta State University\, will present “Geometry: From Fordham Prep to the Cosmos.” \nRelativity is expressed geometrically\, but quantum mechanics is expressed in terms of matrices. Geometric algebra expresses geometrical elements as matrices\, thereby providing a common mathematical language for both relativity and quantum mechanics. The kind of matrix—dyreal\, real\, complex\, quaternionic\, or dyquaternionic—depends only on the metric signature “s” (the number of spatial dimensions minus the number of temporal dimensions). The rank of the matrix depends only on “n” (the total number of dimensions\, spatial plus temporal). Geometric algebras are periodic in “s”\, but recursive in “n”\, thereby providing a way for larger geometries to grow from smaller geometries—either the Euclidean plane or the Minkowskian plane. \nQubits are unit vectors in the Euclidean plane\, whose eigenvalues are the bits\, +1 and -1. The dot product of two qubits gives the Bell correlation between them. The direct product of the geometric algebras of the two planes is the geometric algebra of 4-d space-time\, with vectors (space-time)\, bi-vectors (spin-area)\, tri-vectors (momentumenergy)\, and 4-volume (action) that satisfy the Heisenberg (anti-) Commutation Relations as a consequence of the anti-commutativity of the basis vectors. The next four dimensions are compact and have the symmetries of the standard model of physics. After eight dimensions\, the pattern of geometric algebras repeats\, leading to an exponentially expanding 4-d space-time lattice with the physics of the standard model of physics at each node of the lattice. Thereafter\, the universe continues growing in complexity from the bottom up.

SUMMARY:Physics & Engineering Physics Colloquium
DESCRIPTION:Ronald L. Koder\, Ph.D.\, the James Peace Professor of Physics at the City College of New York\, will present “Utilizing Disorder in Natural and Designed Proteins and Enzymes.” \nThe largest destabilizing force in biopolymer folding is the inescapable configurational entropy loss in going from a disordered unfolded state to an ordered folded state. One way that the energy is minimized in evolution is by using the minimum degree of order in the folded state that is necessary for a specific function. Koder will outline his experiments in introducing this disorder in designed electron transfer enzymes; his utilization of disorder to create high signal sensing platforms that we have used to detect chemical- and bio-terror weapons\, cancer biomarkers\, and cytokines central to COVID-19; and recent biophysical analyses of the human protein elastin— the protein responsible for the elasticity of arterial walls whose entropic elasticity is critical to cardiovascular function.

SUMMARY:Physics & Engineering Physics Colloquium
DESCRIPTION:Christopher Koenigsmann\, Ph.D.\, associate professor\, in the chemistry department at Fordham University\, will present\, “Designing New Nanomaterials for Renewable Energy and Sensor Applications.” \nA key technological shortfall in the development of practical renewable energy and sensor devices is the high cost and poor durability of the precious metal catalysts that drive electrochemical reactions within operating devices. This has hindered the widespread\, commercialization of platinum-based catalysts in blood-glucose meters and in polymer electrolyte membrane (PEM) fuel cells in automobiles. In light of these challenges\, there is a broad effort to design precious metal electrocatalysts and their supports at the nanoscale leading to considerable advancements in catalysts performance. In recent work\, we have focused our efforts on employing solution-based methods to produce alloy-type Pt-based nanostructures with tunable structure\, size\, and composition. The electrochemical properties and electrocatalytic activity of the as-synthesized catalysts toward the oxygen reduction reaction and the oxidation of small organic molecules are examined as a function of the structure of the active sites at the catalytic interface.

SUMMARY:Physics & Engineering Physics Colloquium
DESCRIPTION:Nick Geiser\, FCRH ’17\, will present\, “What good is string theory? The Math & Physics of Strings.” \nString theory is the most promising candidate for the unification of quantum mechanics and gravity in a mathematically consistent framework. Moreover\, string theory is a well-established conceptual and computational tool that has been applied to a wide range of topics\, including particle physics\, astrophysics\, and pure mathematics. In this talk\, Geiser will present a lightning review of the fundamental theories of quantum mechanics (the standard model of particle physics) and gravity (general relativity) before introducing string theory as a consistent theory of quantum gravity. Geiser will then explore some basic stringy calculations\, encountering several famous mathematical objects\, such as the gamma function and the Riemann zeta function\, along the way. Finally\, Geiser will discuss the stringy origins of the “double-copy” between gauge theory and gravity and its application to colliding black holes. \nThis talk assumes familiarity with calculus (integrals).

SUMMARY:Physics & Engineering Physics Colloquium
DESCRIPTION:Jessica Esquivel\, Ph.D.\, associate scientist within the particle physics division in Fermilab’s Muon Department\, will present\, “Can Wobbling Muons Probe Physics Beyond the Standard Model? Fermilab’s Muon g-2 Run 1 Results.” \nOn April 7\, 2021\, Fermilab’s Muon g-2 experiment announced its first results of the precision measurement of the anomalous muon magnetic moment based on its 2018 Run-1 dataset. These results align with the Brookhaven National Laboratory experimental value\, and the combined values increase the tension between experiment and theory from 3.7 to 4.2 sigma. This talk will give an overview of the Fermilab Muon g-2 experiment\, discuss the steps necessary to precisely measure wobbling muons\, why this result has the physics community abuzz\, and what’s next. \nAbout the Speaker\nEsquivel has recently been promoted to associate scientist at Fermilab\, where she works on the Muon g-2 experiment. She is one of roughly 100 Black women with a Ph.D. in physics in the country\, the second black woman to graduate with a Ph.D. in physics from Syracuse University\, and the third Black woman to hold an associate scientist position at Fermilab. She identifies as female\, Black\, Mexican\, lesbian\, neurodivergent\, a physicist\, and Texan. Esquivel is a recognized advocate for creating just and equitable spaces in physics and focuses on the intersections of race\, gender\, and sexuality in her community-engagement efforts. She is a member of APS-IDEA\, co-founder of BlackInPhysics\, part of the Change-Now collective\, and is an AAAS IF/THEN Ambassador. Esquivel has also appeared on CBS’s Emmy-nominated educational program Mission Unstoppable\, on which she discussed the physics behind makeup\, and on the Science Channel’s How the Universe Works\, on which she discussed how neutrinos could be the key to the mysteries of our universe.

SUMMARY:Physics & Engineering Physics Colloquium
DESCRIPTION:Elizabeth Thrall\, Ph.D.\, assistant professor in the Department of Chemistry at Fordham University\, will present “Overcoming Obstacles: Visualizing How the DNA Replication Machinery Bypasses DNA Damage.” \nAcross all domains of life\, DNA is replicated by a multi-protein complex known as the replisome. At the center of the replisome are DNA polymerases\, the enzymes that synthesize new DNA strands using the parental DNA as a template. Although the replisome efficiently and accurately copies undamaged DNA\, it can be blocked by unrepaired lesions on the DNA template. The DNA damage tolerance pathway translesion synthesis (TLS) allows cells to alleviate this potentially lethal blockade. In TLS\, specialized DNA polymerases gain access to the template\, bypass the damage\, and then relinquish the template to allow the replisome to continue normal DNA synthesis. Because TLS polymerases are error-prone\, however\, their access to the template must be tightly regulated to avoid harmful mutations. Using particle-tracking photoactivation localization microscopy (PALM)\, we visualize the behavior of single molecules of the TLS polymerase Pol IV in live Escherichia coli cells. We show that Pol IV is not strongly enriched near sites of DNA replication in normally growing cells but instead is recruited in response to DNA damage. Further\, we identify the protein-protein interactions that are important for this recruitment. These results suggest a mechanism by which the cell limits access of Pol IV to the DNA template\, minimizing unnecessary mutagenesis.

SUMMARY:Physics & Engineering Physics Colloquium
DESCRIPTION:Viviana Acquaviva\, Ph.D.\, professor in the physics department at the CUNY NYC College of Technology and at the CUNY Graduate Center\, will present “Understanding the Universe Using Machine Learning.” \nAstronomy has truly become a “Big Data” science in the last few decades thanks to technological advances in telescopes development and the availability of space-based observations. Machine learning techniques are found to be increasingly useful in solving a variety of problems\, from the automatic classification of galaxy morphology and source identification in crowded fields to estimation of star and galaxy properties\, outlier recognition and anomaly detection\, and dimensionality reduction\, just to quote a few examples. In this talk\, Acquaviva will review some of the most notable applications of machine learning and deep learning to the analysis of astronomical data and present a few specific examples drawn from her research experience in analyzing galaxy spectra and training models on cosmological simulations.

SUMMARY:Physics & Engineering Physics Colloquium
DESCRIPTION:Marc Gershow\, Ph.D.\, associate professor of physics and neuroscience at New York University\, will present “Are You Smarter Than A Maggot?” \nDespite having very few neurons (~104; humans have ~1011)\, the fruit fly larva’s brain is capable of sophisticated computations. The larva coordinates its movement\, navigates its environment\, integrates conflicting sensory inputs\, and learns from experience. Modern tools allow us to record and manipulate the activity of individual neurons in the larva’s brain\, and a “wiring diagram” made using electron microscopy provides a guide to understanding how information flows through “neural circuits.” Gershow will discuss his lab’s work in understanding some of the computations carried out by the larva’s brain and try to give a sense of why this work is being done in the physics department.

DESCRIPTION:Sheehan Ahmed\, Ph.D.\, FCRH 2011\, assistant teaching professor at Rutgers University\, will present “Teaching with ISLE: Facilitating Students to Discover Physics for Themselves.” \nEffectively introducing new students to physics goes hand in hand with using research-based practices for teaching physics. Investigative Science Learning Environment (ISLE) is an inquiry-based approach that focuses on students discovering physical concepts on their own using processes similar to what actual researchers use: observing phenomena\, identifying patterns\, developing hypotheses\, using them to make predictions for testing experiments\, and using these testing experiments to reject inconsistent hypotheses. Ahmed will focus on the particular implementation of ISLE that is being run and developed at Rutgers-Newark and the innovations and challenges that come with it.

SUMMARY:Physics & Engineering Physics Colloquium
DESCRIPTION:Faye McNeill\, Ph.D.\, professor of chemical engineering at Columbia University\, will present “The Air We Breathe: Airborne Transmission of COVID and Air Quality.” \nSince late 2019\, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has spread globally\, causing a pandemic (‘coronavirus disease 2019’ or COVID-19) with dire consequences\, including widespread death\, long-term illness\, and societal and economic disruption. Although initially uncertain\, evidence is now overwhelming that SARS-CoV-2 is transmitted primarily through respiratory droplets and aerosols emitted by infected individuals at close to medium range. As a result\, many effective nonpharmaceutical interventions for slowing virus transmission operate by blocking\, filtering\, or diluting respiratory aerosol\, particularly in indoor environments. McNeill will discuss the evidence for airborne transmission of SARS-CoV-2 and other pathogens\, and implications for engineering solutions to reduce transmission risk. McNeill will also discuss the recent efforts of the Columbia Clean Air Toolbox for Cities Initiative toward improving air quality in cities across the Global South.

In addition to a department overview and personal accounts of the graduate student experience\, they will present their respective computational and experimental research on 2D materials. Wines uses powerful computational resources to obtain the electronic\, magnetic\, and mechanical properties of 2D materials\, with such tools as density functional theory (DFT) and Quantum Monte Carlo (QMC) to discover and engineer new materials for energy applications. Gustafson will speak about light-matter interactions on the sub-picosecond scale. The main thrust of his work involves using an optical-pump THz-probe technique called time-resolved terahertz spectroscopy (TRTS) to study the electronic properties of 2D materials\, fully characterizing a material’s photoconductivity. By sharing their Ph.D. journey\, they hope to promote the graduate physics program at UMBC and hope to attract future applicants.

DESCRIPTION:Javad Shabani\, Ph.D.\, assistant professor of physics at New York University\, will present “Towards Topological Superconductivity in Epitaxial Superconductor-Semiconductor Materials System.” \nA central goal in condensed matter physics is to understand and control the order parameter characterizing the collective state of electrons in quantum heterostructures. For example\, new physical behaviors can emerge that are absent in the isolated constituent materials. With regards to superconductivity\, this has opened a whole new area of investigation in the form of topological superconductivity. This type of superconductivity is expected to host exotic\, quasi-particle excitations\, including Majorana bound states that hold promise for fault-tolerant quantum computing. \nIn this talk\, we first discuss the important role of epitaxial superconductor-semiconductor hybrid systems as an enabling materials platform. We present unprecedented values of transparency and induced gap that could allow us to reach into previously unexplored parameter regimes. In wide Josephson junctions exposed to a magnetic field\, we observe a minimum of critical current accompanied with a phase jump in the superconducting phase. We discuss this observation as a signature of a transition between trivial and topological superconductivity. These findings\, in addition to new directions in approximating edge modes\, reveal a versatile two-dimensional platform to explore mesoscopic and topological superconductivity.

SUMMARY:Physics & Engineering Physics Lecture
DESCRIPTION:Yacine Ali-Haimoud\, Ph.D.\, assistant professor\, Department of Physics\, New York University\, will present\, “Hunting for Dark Matter in the Early Universe.” \nIt is now well-established that a large part of the matter in the universe is some substance that appears to be oblivious to any force but gravity. The nature of this “dark matter” remains a mystery—and is one of the most important questions in modern physics. Could it be a new particle\, as light as an electron\, or might it be made of black holes as massive as many suns? \nIn this talk\, Ali-Haimoud will start by giving a brief overview of modern cosmology\, focusing on the cosmic microwave background (CMB). He will then explain how cosmologists can be so sure about the presence and amount of dark matter\, and illustrate how precise measurements of the frequency spectrum and angular fluctuations of the CMB can help shed light on the nature and properties of dark matter. Ali-Haimoud will discuss CMB tests of feeble dark matter interactions with photons\, electrons\, and nuclei\, as well as the signatures of accreting primordial black holes as a potential dark matter candidate.
