Polarized neutrons for fundamental physics at China Spallation Neutron Source

Wed, Dec 19, 2018, 1:30 pm

In this talk I will give a brief introduction to polarized neutrons and their applications in fundamental measurements, followed by an introduction to CSNS, and several potential fundamental measurements that are under consideration to take place at CSNS.

HET Seminar at IAS | Keisuke Harigaya, School of Natural Sciences, IAS | “Higgs Parity, Strong CP Problem and Unification”

Fri, Dec 14, 2018, 1:45 pm

The quartic coupling of the Standard Model Higgs nearly vanishes at a high energy scale. We show that this is explained by the parity symmetry and its spontaneous break down by the condensation of the parity partner of the Higgs. The parity can solve the strong CP problem.

Hamilton Colloquium Series: Daniel Segre, Boston University, "Metabolic Networks from Genomes to Ecosystems" Jadwin A10

Thu, Dec 13, 2018, 4:30 pm

Microbial ecosystems and their metabolic activity play a fundamental but poorly understood role at multiple scales, from human health to biogeochemical cycles. In fact, metabolism, in addition to being the “engine” of every living cell, mediates competition and cross-feeding between different species, and dictates how cells interact with their...

Physics Group Meeting at IAS | Masahito Yamazaki, KIPMU | “Introduction to Four-Dimensional Chern-Simons Theory”

Wed, Dec 12, 2018, 1:45 pm

I will discuss an approach to integrable models from afour-dimensional Chern-Simons-type gauge theory. For introductionplease have a look at E. Witten arXiv:1611.00592 or K. CostelloarXiv:1308.0370. It might be interesting to look into some Feynmandiagram computations in my paper arXiv:1709.09993 with Edward andKevin (e.g. section 4 and section...

Pheno & Vino Seminar | Masha Baryakhtar, Perimeter Inst. | "Axion and dark photon direct detection" | Jadwin 303

Tue, Dec 11, 2018, 4:00 pm

Abstract:  A well-motivated class of dark matter candidates, including axion-like particles and dark photons, takes the form of coherent oscillations of a light bosonic field. If the dark matter couples to Standard Model photons, it may be possible to detect it via absorptions in a laboratory target.

Quantization of heat flow in the fractional quantum Hall regime - Mitali Banerjee, Columbia

Tue, Dec 11, 2018, 1:00 pm

Topological states of matter are characterized by topological invariants, which are physical quantities whose values are quantized and do not depend on details of the measured system. Among them the electrical Hall conductance, which is expressed in units of e2/h (e the electron charge, h the Planck constant), is easiest to probe.

HET Seminar at IAS | Erich Poppitz, University of Toronto | “’t Hooft Anomalies, High-T, and Low-T Domain Walls in Adjoint Fermion Theories with (or without) Supersymmetry”

Mon, Dec 10, 2018, 2:30 pm

We study t Hooft anomalies of 1-form and 0-form symmetries in SU(N) gauge theories with adjoint fermions, focusing on the rich worldvolume physics of domain walls mandated by anomaly inflow.

Ultracold Molecules in Optical Tweezers Lawrence Cheuk - Harvard University

Mon, Dec 10, 2018, 1:00 pm

The past decades have seen rapid advances in our ability to probe and control atoms. The ability to bring atoms into the ultracold regime has opened up many applications, ranging from creating the most precise clocks to quantum simulation of condensed matter systems. Compared to atoms, molecules have a much richer internal structure.

Gravity Group Lunch Seminar, Paul Steinhardt (Princeton) "Introduction to Bouncing Cosmology"

Fri, Dec 7, 2018, 12:00 pm

This talk will be an elementary introduction to cosmological theories that replace the big bang with a smooth, classical transition from contraction to expansion in order to address many of the fundamental problems of cosmology.

Hamilton Colloquium Series:Xie Chen, Caltech, "Fracton Order: From Foliated Manifold to Quantum Hard Drive", Jadwin A10

Thu, Dec 6, 2018, 4:00 pm

One major open problem in quantum information theory is how to build a quantum hard drive, i.e. a quantum mechanical system that can store quantum information reliably for a very long time without active error correction.

Audience: A free lecture open to the public.

Math Physics Seminar | Jacob Shapiro, Columbia U. | "The topology of strongly-disordered chiral chains" | Jadwin Hall 343

Tue, Dec 4, 2018, 4:30 pm

Abstract:    We show how in the strongly-disordered, gapless regime, the topological properties of chiral chains (class AIII 1D in the Kitaev table) can be read off from the Lyapunov spectrum of the system at zero energy, and prove that these objects are topologically stable in the strongly-disordered gapless regime.
