From nanoelectronics to strongly correlated ultra-cold atoms
| | | My main research interests are in mesoscopic superconductivity,
nanoelectronics and magnetic superfluid. In my early works on mesoscopic superconductivity, I and my collaborators investigated
effects of quantum chaos on BCS pairing states and pointed out
mesocopic pairing states as close analogies of "Lifshitz tails" in disordered non-interacting systems. My last work in the field of nanoelectronics is about the geometric pumping of electrons in an extreme quantum limit; the idea of transporting coherent electrons with little entropy production appears to be an exciting one to many experts working in the field.
Since 2000, I,together with my students and colleagues have made lots of efforts to understand condensates and Mott states of ultra cold spinful bosonic atoms in optical lattices. Vector bosons can condense in
both an internal spin space and the usual momentum space. The condensation in a compact spin space leads to many unexpected new phenomena and has generated much interest. Many new excitations, both topological ones and collective non-topological ones have been studied.
When vector bosons are introduced to an optical lattice, an artificial lattice made of interfering laser beams, the condensation in either spin space or the momentum space might become impossible because of interactions between these bosons. As consequences, more Exotic Correlated States such as spin nematic Mott states, spin singlet condensates and dimerized-valence-crystals states have been discovered to be ground states in various limits.
Most recently, my group has started working on possible application of correlated cold atoms towards Quantum Information Storing. Each state discussed above is fully characterized by a unique class of compact topological field theory models and supports a Hilbert space with some fascinating topology. The journey to explore the implication of the topology of these Hilbert spaces on quantum information storing just started. The other venue is to study Early Universe Physics using cold atoms in lattices.
