TITLE: Quasinormal Modes from Penrose Limits ABSTRACT: In this talk, I will explain how to describe quasinormal modes with a large real frequency using Penrose limits. To do so, I first recall relevant aspects of the Penrose limit, as well as the plane wave spacetimes that arise in this limit, to subsequently tie this together with […]
TITLE: Quantum geometry: how to picture bound electrons in periodic lattices ABSTRACT: The concept of quantum geometry has been at the forefront of condensed matter physics, starting from how quantized Berry curvature leads to quantized Hall conductivity, anomalous velocities in Dirac metals, or other topological responses in a growing list of so-called topological materials. Recently, […]
Title: Dark QCD: the Next Frontier in Dark Matter Abstract: There has been a surge of interest in hidden valley models with new, strong forces, sometimes called "dark QCD". These models propose asymmetric, composite dark matter in the form of "dark hadrons" that would evade direct and indirect bounds as well as typical collider DM searches for […]
Machine Learning the Evolution of Gas from Clouds to Stars
Moon Ying on the topic "Protein assemblies prefer regular growth due to membrane energy penalty during budding" and Mateusz Ratman with the title "Spontaneous spatial sorting by cell shape in growing colonies of rod-like bacteria"
All members of the department are invited and encouraged to attend. The purpose of the meeting will be to make some announcements and to provide information and updates on various research, education, outreach, and administrative initiatives in the department. As with the colloquium, a wine and cheese reception will follow.
TITLE: Photonic Band Gap R&D for Next Generation Axion Haloscopes ABSTRACT: Axions are a well-motivated dark matter candidate particle, which have the potential to simultaneously solve multiple problems in particle physics. As a dark matter candidate, large scale haloscopes, such as ADMX and HAYSTAC, aim to detect axions in the galactic halo by measuring the […]
Talk titles will be available on the CAS wiki page.
Title: Quantum near extremal black holes and anomalies Abstract: The Bekenstein–Hawking formula gives a coarse-grained count of the number of microstates of a black hole, and it is remarkable that it may sometimes be reproduced from a microscopic count in string theory. However, the standard approach (which we will briefly review) typically relies on supersymmetry by counting […]
Condensed Matter & Biological Physics Seminar: Salem Al Mosleh (University of Maryland Eastern Shore) Host: Brian Camley
* Lunch at noon TITLE: Testing Gravity at ever shorter scale: a trip into exotic experimental physics ABSTRACT: Since the times of Henry Cavendish and John Mitchell, the strength of gravity has been measured by comparing it to the reaction of a calibrated mechanical spring. While in the last 60 years planetary measurements (with natural and […]
