Physics 298
Speaker: Sara Haravifard (U. Chicago and Argonne NL)
SrCu2(BO3)2 (SCBO) has corner-sharing Cu2+ spin-1/2 dimers lying on a square lattice, corresponding to the two-dimensional Shastry-Sutherland model. I will present the results of the first single-crystal neutron scattering measurements at high pressure at the Spallation Neutron Source, which... Read More »

Physics 128
Speaker: Sara Haravifard (Univ of Chicago and ANL)
** Please note this event is on MONDAY not Wednesday. ** The interactions that define how spins arrange themselves in a material play a fundamental role in a wide variety of physical phenomena from quantum magnetism to quantum critical phenomena to exotic superconductivity. My talk will build on... Read More »

Physics 278
Speaker: Matt Toups (MIT)
There is a broad effort in the U.S. neutrino physics community to develop the technologies necessary to build a kiloton scale liquid argon time projection chamber (LArTPC) detector for the Long Baseline Neutrino Experiment (LBNE). Liquid argon scintillation light collection is an essential... Read More »

Wednesday, April 9, 2014 - 3:30pm
Physics 128
Speaker: Matthieu Wyart (NYU)
Complex systems are characterized by an abundance of meta-stable states. To describe such systems statistically, one must understand how states are sampled, a difficult task in general when thermal equilibrium does not apply. This problem arises in various fields of science, and here I will focus... Read More »

Raleigh N.C.
Speaker: Felipe J. Llanes-Estrada (Universidad Complutense, Madrid)
The apparent finding of a 125-GeV light Higgs boson closes unitarity of the minimal Standard Model (SM), that is weakly interacting: this is an exceptional feature not generally true if new physics exists beyond the mass gap found at the LHC up to 700 GeV. Such new physics induces departures of the... Read More »

Physics 128
Speaker: Kun Zhao (UCLA)
** Please note this event is on MONDAY not Wednesday and will be held at 3:00pm not 3:30pm. ** Many complex mesoscopic systems, ranging from synthetic colloids to active biological cells, exhibit a rich variety of pattern-forming behavior. In this talk, I will show you how anisotropy in two model... Read More »

Physics 128
Speaker: Joseph Kerckhoff (JILA and NIST)
Whether it's for applications that exploit the ultra-low energy scales, sensitivity, or complexity of quantum systems, quantum mechanics will play an ever increasing role in engineering. In the past decade, the nascent field of quantum engineering has produced quite good devices and clearer... Read More »

Raleigh N.C.
Speaker: Keh-Fei Liu (U. of Kentucky)
I will report a complete lattice calculation of the quark and glue components of the proton momentum and angular momenta. Preliminary results on the quark spin contribution from the anomalous Ward identity will also be reported. Hadron mass can be decomposed in terms of the quark kinetic energy,... Read More »

Physics 298
Speaker: Cenke Xu (UCSB)
Spin liquid states are ground states of quantum spin systems that do not spontaneously break any global symmetry. In the last decade tremendous progresses have been made in searching for spin liquid states in real materials. So far three different kinds of spin liquid materials all show very... Read More »
