Kubo formula and tunneling in the fractional quantum Hall effect

Friday 16 October 2009 at 3.14 a.m.

Computer Science Lecture theatre 1 (CS1) NUIM North Campus

Abstract:

In this talk I will present a short introduction of the Kubo
formula and how it arises in linear response theory. As an example we'll
explore tunneling across a point contact in (1+1) dimensions, which has
applications in the fractional quantum Hall effect. Specifically, the
Kubo formalism can be used to obtain the current-voltage (I-V) relation.
