Speaker(s):

### PGI Virtual Seminar Series | Jonathan Wing-hong Luk, “Some singular spacetimes in general relativity”

Mon, Nov 2, 2020, 12:30 pm

Abstract: I will describe a few classes of solutions to the Einstein equations whose metrics are singular or highly oscillatory, and discuss the relation between them. The singular solutions include as special examples impulsive gravitational waves and null dust shell solutions.

### Hamilton Colloquium Series, Andrei Beloborodov, Columbia University, "Explosive Neutron Stars"

Thu, Oct 29, 2020, 12:00 pm

Neutron stars are by far the strongest known magnets in the universe. Some of them (called magnetars) generate explosions by suddenly dissipating magnetic energy with a rate up to $10^{47}$ erg/s. These magnetic explosions emit giant gamma-ray flares observed in our and neighboring galaxies.

Audience: A free lecture open to the public.

### Condensed Matter Zoom Seminar | Pedram Roushan, Google | " Tuning quantum information scrambling in two-dimensional systems"

Wed, Oct 28, 2020, 1:30 pm

The promise of quantum computers is that certain computational tasks might be executed exponentially faster on a quantum processor than on a classical processor.

Speaker(s):

### PRISM / PCCM Seminar Series Fall 2020

Wed, Oct 28, 2020, 12:00 pm

The Princeton Center for Complex Materials (PCCM) and the Princeton Institute for the Science and Technology of Materials (PRISM) co-sponsor a seminar series that is held on Wednesdays throughout the semester.

### PGI Virtual Seminar Series | Yakov Shlapentokh-Rothman, "Naked Singularities for the Einstein Vacuum Equations: The Exterior Solution"

Mon, Oct 26, 2020, 12:30 pm

Abstract: We will start by recalling the weak cosmic censorship conjecture.  Then we will review Christodoulou's construction of naked singularities for the spherically symmetric Einstein-scalar field system.

### Biophysics Seminar: Allan Drummond, University of Chicago: Rethinking the cellular response to heat shock, from biophysics to physiology| Zoom

Mon, Oct 26, 2020, 12:15 pm

Cells across the tree of life respond to a sudden, nonlethal rise in temperature--heat shock--in similar ways. Following heat shock, proteins and mRNAs form clumps, certain genes turn on, and protein synthesis and cell growth sharply decline.

Audience: A free lecture open to the public.

### Gravity Group Seminar | Status of the Atacama Cosmology Telescope

Fri, Oct 23, 2020, 12:00 pm

Adri Duivenvoorden, Zack Li, Brandon Hensley, Jo Dunkley, and Lyman Page will update us on the status of the Atacama Cosmology Telescope (ACT).

### 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.

The Princeton Center for Complex Materials (PCCM) and the Princeton Institute for the Science and Technology of Materials (PRISM) co-sponsor a seminar series that is held on Wednesdays throughout the semester.

### HET Seminar | Amirhossein Tajdini, University of California, Santa Barbara | "Fast conformal bootstrap and sphere packing in high dimensions" | via Zoom

Mon, Oct 19, 2020, 2:30 pm

### 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!
