Title: Quantized vortices in superfluids

Speaker: Professor Qiang Du, Penn State University

Abstract:

Quantized vortex, a signature of superfluidity,
has been studied for more than fifty years
in the context of superconductivity and in
recent years, it has attracted much attention in
the study of the Bose-Einstein condensates.

In this talk, we will discuss some questions
related to quantized vortices based on the 
Ginzburg-Landau models for superconductivity and the
Gross-Pitaevskii equations for the Bose-Einstein condensation. 
We will also present numerical algorithms for solving
these equations.
