Research achievements

My recent research is in the fields of many–body theory as applied to the strong interacting ultra–cold fermions and bosons.
I have worked on:
  • Strongly Interacting Polarized Fermi Gas
  • Perturbation Theory at BCS–BEC crossover
  • Ultracold fermions in optical lattices with low dimensionality
  • Collective oscillations of Bose gases
  • Dynamics of trapped Bose–Fermi mixtures at zero and finite temperature
  • Super–fluidity of a rotating BEC
  • Theory of quantum measurement
Currently about 50 research papers have been published or accepted in refereed journals, with around 650 ISI citations. These papers include several publications in highly cited letter journals:
  • 1 Nature Physics,
  • 8 Physical Review Letters,
  • 3 Europhysics Letters.
These are closely related to testable predictions and most have been experimentally confirmed.
