Physics Seminar: Pattern Formation and Strong Nonlinear Interactions in Exciton-Polariton Condensates

N-823

Place: Namm 823 Date: Thursday October 22, 2015 Time: 12:00 p.m. Presented by Dr. Li Ge Faculty and students are welcome, light refreshments will be served. Abstract: Exciton-polaritons generated by light-induced potentials can spontaneously condense into macroscopic quantum states that display nontrivial spatial and temporal density modulation. While these patterns and their dynamics can be reproduced

Mathematics and Physics Colloquium: Symmetric Class-0 Subgraphs and Forbidden Subgraphs

N-720

Place: Namm 720 Date: Thursday October 22, 2015 Time: 12:45 p.m. Presented by Prof. Eugene Fiorini Faculty and students are welcome, light refreshments will be served. Abstract: Competition graphs and graph pebbling are two examples of graph theoretical-type games played on a graph under well-defined conditions. In the case of graph pebbling, the pebbling number pi(G)

N-823

Place: Namm 823 Date: Thursday, December 3 at Time: 12:00 PM Presented by Prof. W. Vincent Liu Faculty and students are welcome, light refreshments will be served. Abstract: When interacting ultracold atoms are loaded into the metastable but long lived higher orbital excited bands of an optical lattice, would it be possible for the atoms to

Physics Seminar: Prof. William Wootters:
Why does nature like the square root of negative one?

N-823

Place: Namm 823 Date: Thursday, March 31 2016 Time: 12:00 PM   Presented by Prof. William Wootters Faculty and students are welcome.   Abstract: Quantum mechanics is a probabilistic theory, but the way we compute probabilities in quantum mechanics is quite different from what one would expect from, say, rolling dice or tossing coins.  To get a quantum probability,

Physics Seminar: Negative refractive index for graphene and surface Plasmon instability for hybrid structures

N-823

Presented by: Distinguished Professor Godfrey Gumbs Femtosecond and subfemtosecond time scales typically rule electron dynamics at metal surfaces. Recent advances in experimental techniques allow the experimental study of such dynamics. In this talk, we shall analyze electron dynamics at surfaces and nanostructures with emphasis on screening times, spin dependence of charge transfer of adsorbates and
