The group studies novel
manifestations of quantum mechanics in solids. It is fascinating to see
a bizarre quantum phenomenon appear in what one might expect to be a mundane,
familiar solid object. The research is theoretical, but we often work in
close collaboration with experimentalists. Some specific projects include
(1) Quantum computation - is it possible to make a working
solid state quantum computer?
(2) Electron correlation effects in superconductors - how do the current
vortices in a superconductor move?
(3) Quantum confinement - how does an electron behave when it finds itself
contained in a small solid like a nanocrystal or nanotube, whose size is comparable
to the electron's wavelength?
In general, research problems are addressed both analytically and computationally.
