Experimental Particle Physics Seminar: "Anomaly of Dancing Reactor Antineutrinos"
Soo-Bong Kim, Seoul National University
The Reactor Experiment for Neutrino Oscillation(RENO) started data-taking from August, 2011 and has observed the disappearance of reactor electron antineutrinos to measure the smallest neutrino mixing angle…
Condensed Matter Seminar: "Learning force fields from stochastic trajectories"
Pierre Ronceray, Princeton University
From nanometer-scale proteins to micron-scale colloidal particles, particles in biological and soft matter systems undergo Brownian dynamics: their deterministic motion due to the forces competes with the random…
Astronomy seminar: "Two instruments to start the new decade: HERA for 21cm cosmology and SPARCS to Monitor M-Dwarf flares affecting exoplanets"
Daniel Jacobs, Arizona State University
Two new kinds of instruments are coming of age at the end of this decade: low frequency radio telescopes and cubesats, both being used to probe questions of our cosmic origin and the nature of exoplanets. The…
High Energy Theory Seminar: "Entanglement in gauge theories and gravity"
Jennifer Lin, IAS, Princeton University
In this talk I'll explain why an analogy between entanglement entropy in an emergent gauge theory and in AdS/CFT suggests that the entropy of a black hole may be related to a natural measure on the gauge group in the…
High Energy Theory Seminar: "Complementarity from Identity"
Sergei Dubovsky, New York University
Department Colloquium: “A New Era of Science at Jefferson Lab”
Robert McKeown, Deputy Director for Science, JLAB
The continuous electron beam accelerator facility at Jefferson Lab, built with advanced superconducting radiofrequency (SRF) technology, provides opportunities to discover fundamental new aspects of the structure of…
High Energy Theory Seminar: "Analytic IR-resummation for the BAO peak"
Matthew Lewandowsky, Institut de Physique Théorique (IPhT)
We develop an analytic method for implementing the IR-resummation of 1404.5954, which allows one to correctly and consistently describe the imprint of baryon acoustic oscillations (BAO) on statistical observables in…
High Energy Theory Seminar: "Interfaces and Topological Entanglement in Abelian Chern-Simons Theory"
Jackson Fliss, University of Illinois, Urbana Champaign
Starting from the condensed matter context, we consider the ground state entanglement across (possibly distinct) topological phases separated by a gapped interface. I will explain how addressing this from the…
Condensed Matter Seminar: "Soft Matter Physics of the Evolution of Multi-Cellularity"
Peter Yunker, Georgia Institute of Technology
The evolution of multicellularity set the stage for an incredible increase in the diversity and complexity of life on Earth. The increase in biological complexity associated with multi-cellularity required parallel…
Astronomy seminar: "Cosmological Seed Magnetic Field from Inflation"
Bharat Ratra, Kansas State University
A cosmological magnetic field of nG strength on Mpc length scales could be the seed magnetic field needed to explain observed few microG large-scale galactic magnetic fields. I first briefly review the observational…
