Biophysics Seminar: Susanne Still, University of Hawaii at Mānoa| Thermodynamics of information processing| Zoom
Mon, Apr 19, 2021, 4:00 pm4:00 pm

Living systems need to remember information about their environment in order to take decisions that ultimately ensure survival. But storing information about past experiences costs energy, while only a fraction of the vast amount of information available can be useful to the living system. An intelligent memory formation strategy should take…

PGI Virtual Seminar Series | Claude Warnick, Cambridge University "Quasinormal modes of black holes"
Mon, Apr 19, 2021, 12:30 pm12:30 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. In this talk I will review the problem of finding quasinormal frequencies, and discuss recent work…

PGI Virtual Seminar Series | Marcelo Disconzi, Vanderbilt University "General-relativistic viscous fluids
Mon, Apr 12, 2021, 12:30 pm12:30 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. Studying the quark-gluon plasma also provides a window into the earliest moments…

Biophysics Seminar: Nikta Fakhri, MIT |Broken symmetries in living matter | Zoom
Mon, Apr 12, 2021, 12:00 pm12:00 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. In this talk, I will discuss experimental tools and conceptual frameworks we develop to uncover laws governing order, phase transitions and…

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 pm12:00 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. In this talk, we report the results of internal consistency tests performed on the data to control against instrumental systematics, and…

P4: Prospective Physics PhD Preview
Fri, Apr 9, 2021Sat, Apr 10, 2021

Attention early-undergraduates interested in learning more about graduate school!
The Princeton Physics Department Ambassadors are hosting a 1.5-day virtual workshop with Princeton Physics faculty and grad students. We will focus on how to get involved with research, crafting grad school applications, and understanding life as a…

Condensed Matter Zoom Seminar | Charles Kane, U Penn.| "Translation symmetry enriched topological phases"
Wed, Apr 7, 2021, 2:00 pm2:00 pm

The interplay between symmetry and topology allows a rich variety of electronic phases.  For layered systems, symmetry under translation by one layer protects the 3D weak topological insulator, which can be viewed as a stack of 2D topological insulators and the 2D 'weak topological superconductor', which is a stack of 1D topological…

PGI Virtual Seminar Series | Anna Y. Q. Ho, UC Berkeley "The Landscape of Relativistic Stellar Explosions"
Mon, Apr 5, 2021, 12:30 pm12:30 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 pm12:00 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. Does…

Condensed Matter Zoom Seminar | Eugene Demler, Harvard | "A new perspective on magnetic polarons from cold atoms"
Wed, Mar 31, 2021, 2:00 pm2:00 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. In…

PGI Virtual Seminar Series | Lydia Bieri, University of Michigan "New Structures in Gravitational Radiation"
Mon, Mar 29, 2021, 12:30 pm12:30 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. In general relativity (GR), most studies so far have been devoted to sources like binary black hole mergers…

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 pm12:15 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. phase-synchronization are putative mechanisms for the coordination of neuronal processing and…
