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 […]
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.
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 […]

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, […]
How to Reionize the Universe: Lessons from Low RedshiftAnne Jaskot (Williams College)
Title: Precision measurements are having a moment: recent results in leptons and why they matter, Abstract: The past three years have seen three dipole-moment measurements of record-breaking accuracy – the magnetic dipole moments (aka “g-2”) of the muon and of the electron, and the electric dipole moment (EDM) of the electron. I will focus at first […]

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 […]
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 […]
Kramers Nodal Lines, Weyl Fermions and Large Anomalous Hall Effect in SmAlSi and InxTaS2 Kramers nodal lines (KNLs) are a special type of Weyl line degeneracies that connect time reversal invariant momenta (TRIM). KNLs are robust to spin orbit coupling (SOC), and are inherent to all non-centrosymmetric achiral crystal structures. In this talk, I will […]
