Early Galaxies from Rare Inflationary Processes Rare Poisson processes during cosmic inflation can generically lead to rare, high-redshift (z) galaxies. Focusing on inflationary heavy particle production as one example of a Poisson process, I will derive the redshift distribution, masses, and number densities of such early galaxies. The James Webb Space Telescope (JWST) is a powerful probe […]
Atomistic view of the phase equilibrium and material properties of biomolecular condensates Abstract: Biomolecular condensates, formed through liquid-liquid phase separation, mediate crucial cellular functions and are linked with neurodegeneration and cancer. To reach a fundamental understanding of their phase equilibrium and material properties, we have integrated experimental techniques including optical tweezers and fluorescence imaging with […]
TITLE: Quantum Control of Quantum Materials, ABSTRACT: Coherently engineering quantum states with light is a key frontier in the control of quantum materials. Over the last two decades, ultrafast lasers have revealed a variety of emergent topological, magnetic, and superconducting states in quantum materials driven far from equilibrium. Early experiments mainly adopted incoherent excitation strategies, […]
Worldline effective theories and gravitational dynamicsWorldline effective theories are incredibly useful tools for studying the dynamics of spatially compact systems, with gravitational binaries being a perfect example. In particular they allow for the import of many tools from quantum field theory, eg. Feynman diagrams, loop integration techniques, dimensional regularization, renormalization group, etc. Work in recent […]

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: 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: 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: 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 […]
