Nov. 20 Club Meeting: Joseph Prestigiacomo

Topic to be discussed:
Glassy Dynamics of the Superconductor-Insulator Transition of Ultrathin Granular Al Films in a Parallel Magnetic Field

Abstract:
The investigation of the dynamics in glassy systems (magnetic spin glass, electron glass, etc.) have proven to be very useful in understanding the connections between non-equilibrium behavior and their microscopic origins.  In this talk, I review a relatively overlooked system exhibiting slow glassy dynamics, the first-order superconductor-insulator transition of ultrathin granular aluminum films in a parallel magnetic field.  These films may constitute a new class of glassy system, a Josephson glass.

Time: Nov. 20, Tuesday, noon.

Location: Rm. 435, Nicholson Hall.
