### Condensed Matter Zoom Seminar | Dmitri Efetov, ICFO | "Magic Angle Bilayer Graphene - Superconductors, Orbital Magnets, Correlated States and beyond"

Wed, Oct 21, 2020, 1:00 pm

When twisted close to a magic relative orientation angle near 1 degree, bilayer graphene has flat moire superlattice minibands that have emerged as a rich and highly tunable source of strong correlation physics, notably the appearance of superconductivity close to interaction-induced insulating states.

### Biophysics Seminar: Stefano Allesina, University of Chicago: Predicting coexistence in experimental ecological communities| Zoom

Mon, Oct 19, 2020, 12:15 pm

When experimenting with a large pool of species, a common problem is to determine a priori whether a certain subset of species can coexist when co-cultured. We propose a simple statistical model in which a number of species assemblages are observed, and the coexistence of novel assemblages is predicted out-of-fit.

Audience: A free lecture open to the public.

### Grad Life @ Princeton Physics

Fri, Oct 16, 2020, 4:00 pm

Are you considering applying to a physics graduate program? Did you know that you get paid to be a grad student? Ph.D. programs in STEM fields are full-time jobs with all the benefits: no tuition and getting paid to research and learn!

### 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.

### Gravity Group Seminar | Javier Romualdez, Steven Benton, and Steven Li (Princeton University), "An Introduction to SuperBIT & GigaBIT: The Ups and Downs of Balloon-borne Optical Astrophysics"

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.
