[Patterson, Robin L.]

Please join us for the Physics Colloquium today, at 3:45 PM in The Robert Smith Seminar Room. There will be a reception at 3:30PM in the Atrium. Details concerning the talk are as follows:

Speaker:         Kin Chung Fong (Raytheon)
Date:             Tuesday, January 9, 2018
Time:             3:45PM
Place:            1080 Physics Research Building, The Robert Smith Seminar Room
Title:              What Can the Hydrodynamics in Solids Teach Us?



Abstract:   Physicists have long been using the Fermi gas to understand the electrons in conductors. However, this paradigm has been challenged in the strongly correlated systems and, more recently, in the high purity materials, graphene, as well as Weyl semimetals. The interaction in these many-body quantum systems can lead a new collective behavior described by the hydrodynamics in long time and length scales. This new regime not only modifies the conventional electrical and thermal transport in condensed matter physics, but also has deep connections to other areas such as the anti-de Sitter/conformal field theory (AdS/CFT) and quark-gluon plasma in the heavy ion collider. In this talk, we will discuss the experiment showing the breakdown of Wiedemann-Franz law in graphene, how the electrons may flow like honey, and how we can use the Dirac point physics to detect a single photon. We will explore the potential applications of graphene-based low energy photon counters in the superconducting quantum computation and measurement of the cosmic infrared background in future space missions.
