Gravity Group Lunch Seminar, Justin Ripley | DAMTP "Classical modifications to Einstein's General Relativity around black holes"

Gravity Group Lunch Seminar, Justin Ripley | DAMTP "Classical modifications to Einstein's General Relativity around black holes"
Fri, Oct 16, 2020, 12:00 pm

In this talk I will discuss recent work on the dynamics of black holes in Einstein dilaton Gauss-Bonnet (EDGB) gravity. This modified gravity theory can be motivated by effective field theory reasoning, and admits scalarized black hole solutions.

HET Seminar | Tarek Anous, University of Amsterdam | "Towards a microscopic model of AdS fragmentation" | via Zoom
Fri, Oct 9, 2020, 1:45 pm

Abstract: A salient feature of black holes near extremality is the appearance of an AdS$_2$ throat in their near-horizon geometry. Depending on the underlying theory, these AdS$_2$ throats may be unstable to fragmentation,  wherein a single throat is instead replaced by a tree-like structure of branched AdS$_2$ throats.

Biophysics Seminar: Gurol Suel, University of California San Diego| The role of inorganic ions in bacterial resilience
Mon, Sep 28, 2020, 12:15 pm

We have been working to measure and understand how ion fluxes and ionic interactions regulate fundamental biological processes, and in particular promote stress tolerance in bacteria. I will present our recent work that builds on our discovery of action potentials generated within bacterial biofilms.

Gravity Group Seminar | Paul Steinhardt, "Cosmological Bounces and Bouncing Cosmology"
Fri, Sep 25, 2020, 12:00 pm

The talk will introduce the group working on cosmological theories in which the big bang is replaced by a smooth, non-singular bounce and the large-scale properties of the universe are explained by a period of slow contraction that precedes the bounce.

FPO - Xiaowen Chen - "Statistical Physics Approaches to Collective Behavior in Networks of Neurons"

FPO - Xiaowen Chen - "Statistical Physics Approaches to Collective Behavior in Networks of Neurons"
Thu, Sep 24, 2020, 2:00 pm

In recent years, advances in experimental techniques have allowed for the first time simultaneous measurements of many interacting components in living systems at almost all scales, making now an exciting time to search for physical principles of collective behavior in living systems.
