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: 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 »

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 »

Physics 298
Speaker: Ted Pudlik (Boston Univ & Duke)
Some of the simplest systems accessible to experiments with ultracold gases in optical lattices are dimers: atoms in a double-well optical lattice, or atoms in a single optical trap, but with two interacting spin states. These systems are very accurately represented by the Bose-Hubbard dimer. A... Read More »

Teer 106
Speaker: Chris Collins (OIT), Jimmy Dorff (Physics), William Shaw (Library/Digital Scholarship), Drew Stinnett (OIT)
This two-day / six-unit course will provide students with a basic introduction to Linux and Unix systems in use in many of the biological and computational research departments around campus. Attendees will have access to a Linux computational server to practice various tasks and perform labs in... Read More »

Physics 298
Speaker: Roy Lacey (Stonybrook)
It is shown that the acoustic scaling patterns of anisotropic flow for different event shapes at a fixed collision centrality (shape-engineered events), provide robust constraints for the event-by-event fluctuations in the initial-state density distribution from ultrarelativistic heavy ion...

Physics 298
Speaker: Fan Zhang (Univ. of Pennsylvania)
The discovery of topological band insulators has created a revolution in condensed matter physics. We generalize the essential idea of band inversion and symmetry protection to experimentally feasible superconducting systems with time-reversal symmetry. When such a one-dimensional system becomes... Read More »
