### 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.

### High Energy Experiment Seminar-Stephane Cooperstein UCSD-"First Evidence for Higgs Boson Decay to Muons"

Thu, Oct 15, 2020, 2:00 pm

Abstract: Probing the Higgs boson coupling to the muon is one of the last experimentally accessible frontiers in the direct measurement of Higgs boson couplings at the LHC.

### HET Seminar | Senthil Todadri, Massachusetts Institute of Technology | “Compressible Quantum Matter: General Constraints, Emergent Symmetries, and Anomalies” | via Zoom

Mon, Oct 12, 2020, 2:30 pm

Abstract: I will discuss properties of phases of matter in systems with a global U(1) symmetry and a (possibly discrete) translation symmetry.

### 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.

Fri, Oct 2, 2020, 12:00 pm

The Super-pressure Balloon-borne Imaging Telescope (SuperBIT) is the first-of-its-kind, three-axis stabilized, high-resolution, wide-field imager designed to provide weak lensing measurements in near-UV to near-IR bands (300–1000 nm).

### Hamilton Colloquium Series, Leonid Mirny, MIT, "Physics of Your Chromosomes" via Zoom

Thu, Oct 1, 2020, 12:00 pm

DNA of the human genome is 2 meters long and is folded into chromosomes that fit in a 10-micron cellular nucleus. I will discuss physical principles that govern folding of long DNA molecules, including phase separation, topological effects in polymer systems, and non-equilibrium phenomena.

Audience: A free lecture open to the public.

### 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.

Audience: A free lecture open to the public.

### HET Seminar | Oscar Varela, Utah State University | "AdS4/CFT3 Squashed, Stretched, Warped and Invaded" | via Zoom

Fri, Sep 25, 2020, 1:45 pm

The spectrum of single-trace operators of holographic CFTs at strong coupling and large N can be mapped to the spectrum of Kaluza-Klein modes over the dual AdS supergravity solutions.

Speaker(s):

### 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"

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.
