High energy physics theory seminar: Dragan Huterer (University of Michigan)

Bloomberg 475

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 […]

Department-wide colloquium: Chris Overstreet (JHU)

Bloomberg 272 - Schafler Auditorium

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 […]

High energy physics theory seminar: Jordan Wilson-Gerow (Carnegie Mellon)

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 […]

Condensed matter and biological physics seminar: Matteo Mitrano (Harvard University)

Bloomberg 462

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, […]

Department-wide colloquium: Eric Cornell (JILA)

Bloomberg 272 - Schafler Auditorium

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 […]
