His work has spanned several areas of AMO physics, including trapped ions, Rydberg atoms, ultracold polyatomic molecules, quantum information, and precision searches for new physics with AMO systems.
Title: From quantum information to black holes and cosmology, Abstract: Black holes have not just become laboratories for astronomers, but also present some of the deepest unsolved problems in theoretical physics. During the past decade surprising connections have been made between ideas from quantum information and gravitational physics. In this talk I will explain several aspects […]

TITLE: A Physicist Following Faraday's Hint in the Search for Quantum Gravity, ABSTRACT: Faraday's discovery of electromagnetic induction occurred due to his inference that magnetic fields about wires must be as wheels about a spoke. This visualization led to understanding the physics of B-fields. Currently mathematically enabled research uses computers to augment this important tool. The speaker will discuss […]
Title: Cauchy-characteristic matching, Abstract: Cauchy-characteristic matching is a novel numerical-relativity technique that enables the evolution of Einstein’s equations on an effectively infinite computational domain. In this talk, I will present our recent successful applications of this method to binary black hole mergers, and demonstrate its transformative potential for modeling tail and memory effects in eccentric binaries.

Title: Ultracold Molecules: From Quantum Chemistry to Quantum Computing, Abstract: At ultracold temperatures, we can prepare reactants in well-defined quantum states. Doing so allows us to study the quantum dynamics of individual reaction channels. I will present our work on ultracold chemistry using triplet NaLi molecules. First, we discovered strongly spin dependent chemistry. For certain […]
Title: New Photo-galvanic effects, Abstract: The conventional device to convert light to electrical current uses two different kinds of doped silicon merged together known as pn junction or heterostructures. The current only flows one way in the pn junction due to a built-in electric field. Fabricating such heterostructures requires sophisticated thin film deposition methods. In […]

Black (hole) Coffee is a space for students, postdocs, and professors to discuss cutting-edge research on all things black holes, spanning both observations and theory.
Title: Where is tree-level string theory? Abstract: Tree-level string theory extends Einstein gravity by an infinite set of massive higher spin particles. From a purely spacetime perspective (if we didn’t know about the worldsheet picture) the consistency of string amplitudes would appear truly miraculous. This prompts the question: is string theory the unique framework for a higher […]
Alex Szalay will present on the intersection of machine learning and astrophysics/cosmology.
Host: Jazzmin Victorin Title: “Emergent metallicity and superconductivity at oxide heterointerfaces” Abstract: Perovskite-structured complex oxides exhibit a diverse array of physical properties, including magnetism, superconductivity, ferroelectricity, and metal-insulator transitions. The electronic, structural, and magnetic interactions at interfaces formed between crystalline, atomically-thin layers of these materials lead to the emergence of novel phases. Advances in the […]
Title: Polymer models for the prediction of 3D structure and transcription in human chromatin, Talk abstract: Transcription is a fundamental cellular process, and the first step of gene expression. In human cells, it depends on the binding to chromatin of various proteins, including RNA polymerases and numerous transcription factors (TFs). Observations indicate that these proteins […]

Title: Dynamic Jahn-Teller effect and a multi-polar order in 5d double-perovskites, The properties of strongly correlated systems have been at the forefront of scientific research for many decades. Typically focused on 3d transition metal compounds, it was often enough to consider only two relevant energy scales, the hopping integral and on-site Coulomb repulsion. In recent […]
TITLE: Cosmological results from the Dark Energy Spectroscopic Instrument, ABSTRACT: A quarter-century after the discovery of the accelerated expansion of theuniverse, the constraints on dark energy that powers this acceleration havebecome very good, but physical nature of dark energy remains elusive. I willpresent and discuss cosmological results from the measurement of baryonacoustic oscillations (BAO) in […]

TITLE: Precision measurement in tabletop experiments, Abstract: Many theories of physics beyond the Standard Model predict small deviations from Standard Model behavior at low energy scales. We can search for such deviations by performing precision measurements in "tabletop" experiments. In this talk, I will describe some of the frontiers of research in this field. I […]
