Exploring the Landscape of Complex Quantum States: From New Phases of Matter to Robust Schemes for Quantum Computation - Sagar Vijay, 303 Jadwin***NEW TIME 1:30***

Wed, Feb 6, 2019, 1:30 pm

Abstract:  We present recent advances in our understanding of (i) exotic quantum phases of matter in three dimensions, and (ii) robust mechanisms for storing and processing quantum information, that have been enabled by new techniques to study highly-entangled quantum states.  First, we introduce  new kinds of gapped quantum phases in three...

Hunting The Heavy Wino - Tracy Slatyer, MIT, 303 Jadwin

Tue, Feb 5, 2019, 4:00 pm

Abstract: Pure wino dark matter, transforming as a triplet under the SU(2) group of the Standard Model, provides an illustrative example of heavy weakly-interacting dark matter that is not yet excluded by direct and collider searches. The most stringent constraints on wino dark matter come from astrophysical searches for its annihilation...

Vignettes in Physical Mathematics - Natalie Paquette - Joseph Henry Room

Tue, Feb 5, 2019, 2:30 pm

Abstract: Fundamental physics generates new mathematics. String theory and quantum field theory leverage exact and infrared dualities to provide equivalent descriptions of physical objects, some of which admit rigorous definitions; dual pairs of objects are sometimes even formalized using two a priori distinct areas of mathematics.

Condensed Matter Seminar: Oskar Vafek-FSU-"Strong Coupling Phases of Partially Filled Twisted Bilayer Graphene Narrow Bands"

Mon, Feb 4, 2019, 2:00 pm to 3:00 pm

When the twist angle of a bilayer graphene is commensurate and near the `magic' value, there are four narrow bands near the neutrality point, each two-fold spin degenerate. These bands are separated from the rest of the bands by energy gaps.

Title: Geometry and Topology in Quantum Materials - Qiong Ma, MIT

Mon, Feb 4, 2019, 1:00 pm

      Finding new phases of matter and understanding their physical properties are primary goals of condensed matter physics. Over the past decade, topological phases of matter have taken center stage in condensed matter research, culminating in the 2016 Nobel Prize.

HET Seminar at IAS | S. James Gates, Jr., Brown University | “Under Construction: A Progress Report on a Theory of SUSY Representations”

Mon, Jan 28, 2019, 2:30 pm

Compact Lie Algebras su(N) have aspects of their representations conveniently expressed in terms of matrices, but they also have some aspect that are most conveniently described by terms of graphical means, i.e. weight spaces, root space, Dynkin diagrams. Component fields, superfields, and superspace are all equivalent to using matrices.

Exploring synthetic quantum matter in superconducting circuits

Mon, Jan 21, 2019, 1:00 pm

Superconducting circuits have emerged as a competitive platform for quantum computation, satisfying the challenges of controllability, long coherence and strong interactions. Here we apply this toolbox to a different problem: the exploration of strongly correlated quantum materials made of microwave photons.

Special Seminar, Nathan Lourie | Dicke Candidate "Sub-arcminute Galactic Polarimetry with the Next Generation Balloon-borne Large-Aperture Submillimeter Telescope (BLAST-TNG)"

Atomic Physics Seminar | Nathan Schine, UChicago | "Quantum Hall Physics with Photons"

Thu, Jan 17, 2019, 3:00 pm

Topological materials have recently become a distinct focus in condensed matter physics, appearing famously in the quantum Hall effect and topological insulators. In these materials, certain essential properties are governed by ‘topological invariants,’ quantities insensitive to local perturbation or manipulation.

Special Seminar-PAS Dicke Candidate-Andy Tan-University of Maryland-"Status and Prospects of the PandaX Experiment"-Jadwin 303

Wed, Jan 16, 2019, 2:00 pm to 3:00 pm

The Particle and astrophysical Xenon (PandaX) project is a series of xenon-based ultra-low background experiments in the China JinPing underground Laboratory (CJPL) targeting the unknown physics of dark matter and neutrinos.

Special Seminar, Saptarshi Chaudhuri | Dicke Candidate "Quest for the QCD Axion: DM Radio and Fundamental Limits of Electromagnetic Detection"

Tue, Jan 15, 2019, 3:00 pm

The QCD axion, originally proposed as a solution to the strong CP problem, is also a well motivated dark-matter candidate. Recently, a number of experimental proposals have emerged to search for QCD axion dark matter over the entire allowed mass range (~1 peV-1 eV).

Special Seminar- HEP Dicke Candidate-Yi Jia-MIT-"Precision Measurement of Elementary Particle and Nuclei Fluxes in Cosmic Rays with AMS on the International Space Station" (ISS)

Tue, Jan 15, 2019, 11:00 am to 12:00 pm

The Alpha Magnetic Spectrometer (AMS) is a general purpose high energy particle detector which was installed on the International Space Station (ISS) on May 19, 2011 to conduct a unique long term mission of fundamental physics research in space.
