PCTS: Polarized Radiation from Supermassive Black Holes

Biophysics Seminar: Justin Kinney, Cold Spring Harbor Laboratory| Massively parallel assays, machine learning, and the biophysics of gene regulation| Zoom

Biophysics Seminar: Justin Kinney, Cold Spring Harbor Laboratory| Massively parallel assays, machine learning, and the biophysics of gene regulation| Zoom
Mon, May 10, 2021, 12:15 pm

Gene expression in all organisms is controlled by short DNA and RNA sequences called cis-regulatory elements (CREs). Proteins in the cellular milieu bind to nucleic acid sequences present within CREs, interact with one another, and thus form macromolecular complexes that modulate the expression of nearby genes.

Audience: A free lecture open to the public.

PCTS: Polarized Radiation from Supermassive Black Holes

Gravity Group Lunch Seminar | Yilun Guan (Pittsburgh) & Brandon Hensley (Princeton) "The ACT View of the Galactic Center"

Gravity Group Lunch Seminar | Yilun Guan (Pittsburgh) & Brandon Hensley (Princeton) "The ACT View of the Galactic Center"
Fri, May 7, 2021, 12:00 pm

We present new maps of the Galactic Center in total intensity and polarization made with the Atacama Cosmology Telescope (ACT). We combine dedicated, arcminute-resolution ACT observations over a 32 deg^2 field with Planck intensity and polarization data at similar frequencies to produce maps with fidelity on both small and large angular scales...

FPO - Xinran Li - The energy resolution and the energy deposition processes in disordered targets for rare-event searches
Tue, May 4, 2021, 9:00 am

Underground rare-event search is a substantial branch in particle physics, in which particle dark matter (DM) direct detection and neutrinoless double β decay (0νββ) are two major topics. The elusive nature of the signals puts stringent requirements on the detector contamination level. Some particular interactions also require specific...

FPO - Yantao Wu - "Variational Monte Carlo Renormalization Group”
Mon, May 3, 2021, 2:00 pm
The renormalization group is an important method to understand the critical behaviors of a statistical system. In this thesis, we develop a stochastic method to perform the renormalization group calculations non-perturbatively with Monte Carlo simulations. The method is variational in nature, and involves minimizing a convex functional of the...

PGI Virtual Seminar Series | Anna Ijjas MPI for Gravitational Physics (Albert Einstein Institute) & Institute for Gravitational Physics, "Ultralocality and the robustness of slow contraction to cosmic initial conditions"
Mon, May 3, 2021, 12:30 pm

Abstract: I will discuss the detailed process by which slow contraction smooths and flattens the universe using an improved numerical relativity code that accepts initial conditions with non-perturbative deviations from homogeneity and isotropy along two independent spatial directions.

The rod-shaped bacterium Escherichia coli proliferates by a process of elongation, followed by constriction at its centre to create new cell poles. Despite intense study, some apparently simple questions about the dynamics of growth and division in E.

Condensed Matter Zoom Seminar | Siddharth Parameswaran | "Topology and broken symmetry of excitons in two-dimensional materials"
Wed, Apr 28, 2021, 2:00 pm

I will discuss recent  theoretical work on exciton physics in two-dimensional materials. First, I will focus on the neutral particle-hole pair excitations of correlated “orbital Chern insulators” recently detected in twisted bilayer graphene, whose approximately flat conduction and valence bands have equal and opposite non-zero Chern number.

Mon, Apr 26, 2021, 12:30 pm

Gravitational waves from the coalescence of compact binaries provide a unique opportunity to test gravity in the strong field regime. In particular, the postmerger phase of the gravitational signal is a proxy for the nature of the remnant.

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.
