Research:
Current interest:
With the ultimate success of techniques for trapping and cooling
atoms developed and improved gradually since the 1980s, first atomic
Bose gases and then atomic Fermi gases have emerged as unique
testing grounds for many theories of exotic matter in nature,
allowing for the creation of complex yet very accessible and
controllable many-body quantum systems. These atomic systems
offer unique opportunities as opposed to condensed matter systems
in which the lack of precise experimental control has hindered
the development of techniques that could systematically probe
the effects of strong correlations. In particular, I am currently interest in
Many-body cold-atom physics in general (Hubbard models, superfluidity, BEC, etc.)
Atomic Fermi-Fermi, Bose-Bose and Bose-Fermi mixtures.
Topological phases of matter.
Artificial Abelian and non-Abelian gauge fields.
Ph.D. work (BCS-BEC crossover): The focus of my Ph.D. research was on
the analysis of the BCS-BEC evolution in superfluid Fermi gases. When the
interaction between atoms is varied, the ground state evolves from
Bardeen-Cooper-Schrieffer (BCS) limit of largely overlapping Cooper
pairs to the limit of tightly bound small composite molecules which
undergo Bose-Einstein condensation (BEC). This is an important topic
of current research not only for the atomic and molecular physics
communities, but also for the condensed matter, nuclear, high energy
and astrophysics communities, where models for superfluidity have been
investigated in various contexts.
