PGI Virtual Seminar Series | Claude Warnick, Cambridge University "Quasinormal modes of black holes"

Mon, Apr 19, 2021, 12:30 pm

During its ringdown phase a perturbed black-hole produces radiation at characteristic (complex) frequencies, much like the normal frequencies of a guitar string. These quasinormal frequencies carry information about the geometry of the black hole.

PGI Virtual Seminar Series | Marcelo Disconzi, Vanderbilt University "General-relativistic viscous fluids

Mon, Apr 12, 2021, 12:30 pm

The discovery of the quark-gluon plasma that forms in heavy-ion collision experiments provides a unique opportunity to study the properties of matter under extreme conditions, as the quark-gluon plasma is the hottest, smallest, and densest fluid known to humanity.

Biophysics Seminar: Nikta Fakhri, MIT |Broken symmetries in living matter | Zoom

Mon, Apr 12, 2021, 12:00 pm

Active processes in living systems create a novel class of non-equilibrium material composed of many interacting parts that individually consume energy and collectively generate motion or mechanical stress.

Audience: A free lecture open to the public.

Gravity Group Seminar | Xue (Sherry) Song, Joseph van der List, and Corwin Shiu, PU "B-mode Constraint from SPIDER's First Flight"

Fri, Apr 9, 2021, 12:00 pm

SPIDER is a balloon-borne telescope designed to map the B-mode polarization of the cosmic microwave background (CMB) on degree angular scales. SPIDER’s 2015 flight mapped 4.8% of the sky at 95 and 150 GHz.

Condensed Matter Zoom Seminar | Charles Kane, U Penn.| "Translation symmetry enriched topological phases"

Wed, Apr 7, 2021, 2:00 pm

The interplay between symmetry and topology allows a rich variety of electronic phases.

PGI Virtual Seminar Series | Anna Y. Q. Ho, UC Berkeley "The Landscape of Relativistic Stellar Explosions"

Mon, Apr 5, 2021, 12:30 pm

Abstract: For the last half-century, relativistic outflows accompanying the final collapse of massive stars have predominantly been detected via high-energy emission, as long-duration gamma-ray bursts (GRBs). From wide-field optical and radio time-domain surveys, there have been hints of related phenomena at lower energies, such as X-ray...

Gravity Group Lunch Seminar | Oliver Philcox, PU "Have we exhausted the galaxy two-point function?"

Fri, Apr 2, 2021, 12:00 pm

Throughout the past three decades, the analysis of spectroscopic surveys has focussed around the two-point function of the galaxy overdensity field, masquerading either as the correlation function or the Fourier-space power spectrum. Today, theoretical interest has shifted towards other statistics, in particular the higher-point functions.

Condensed Matter Zoom Seminar | Eugene Demler, Harvard | "A new perspective on magnetic polarons from cold atoms"

Wed, Mar 31, 2021, 2:00 pm

What can we learn about a many-body system when we measure every constituent particle? Current experiments with ultracold atoms provide snapshots of many-body states with single particle resolution. I will present a recent application of this method to study magnetic polarons in antiferromagnetic Mott insulators.

PGI Virtual Seminar Series | Lydia Bieri, University of Michigan "New Structures in Gravitational Radiation"

Mon, Mar 29, 2021, 12:30 pm

Gravitational waves transport information from faraway regions of the Universe. Since the first detection of gravitational waves by Advanced LIGO in September 2015, several other events have been recorded by the LIGO/VIRGO collaboration.

Biophysics Seminar: Satu Palva, University of Helsinki and University of Glasgow| Multi-scale synchronization dynamics in human cognition| Zoom

Mon, Mar 29, 2021, 12:15 pm

Perception, attention and working memory are fundamental cognitive functions, which are based on parallel processing in many brain areas. Neuronal oscillations at sub-second timescales and their phase correlations a.k.a.

PGI Virtual Seminar Series | Chris White, PU "Misaligned Accretion Flows and Their Impact on Black Hole Observations"

Mon, Mar 22, 2021, 12:30 pm

A priori it would be surprising if all low-luminosity supermassive black holes, such as those in the centers of M87 and our own galaxy, had accretion disks aligned with their spin.
