Quantized vortices in typeII superconductors (for details see Qiang's publications) 

Our research in this direction has
focused on the study of quantized vortex dynamics in
superconductors
using mezoscale models as typified by the celebrated
GinzburgLandau model (equations) (for
vortices in Bose Einstein condensates, see Gallery 2). Though we have also worked on the microscopic
BCS models that can be used to understand the basic structure of
superconductors and of the atomic and subatomic behavior of these materials,
as well as the macroscopic vortex density and critical state models that
can be of use for the design of devices. Mezoscale models are of great
use in understanding important phenomena in superconductors such as
vortex nucleation, motion and interaction, vortex pinning,
critical fields and currents, Josephson effects, inhomogeneities and
fluctuations, vortex glass and vortex fluid structures, resistivity, etc.
Our efforts in superconductivity center on the following aspects:
