My research interests are associated with the many-body quantum systems, such as atomic nuclei, atoms, molecules and atomic clusters. The great variety of quantum-mechanical phenomena that abound in these systems make them the unique laboratories for testing quantum mechanics, while their complexity poses an unprecedented challenge for the theory.

In particular my research interests concern:

Physics of cold atomic gases: superfluidity, thermodynamics, exotic phases, Bose-Einstein Condensation (BEC), physics of BEC-BCS crossover, dynamics of superfluid vortices, viscosity.

Physics of atomic nuclei: structure of atomic nuclei at extreme conditions: high angular momenta, exotic deformations, large mass numbers, large neutron to proton ratio.

Nuclear dynamics: fission & fusion, induced fission, low energy reactions.

Neutron stars: structure and stability issues, superfluid properties.

Concerning general theoretical issues related to quantum many body systems:
- Path Integral Monte Carlo approach to strongly correlated Fermi systems
- Density Functional Theory (static and time-dependent)
- Non-linear dynamics,  chaotic motion, semiclassical methods,
- Non-equilibrium statistical mechanics (transport theory),

Current research interests (with links to talks in pdf):

• Cold and dilute atomic gases.
  
• Dynamics of superfluid systems far from equilibrium: vortex formation, interaction and dynamics (movies generated by Jaguar)
  
• Casimir effect (fermionic Casimir energy).
• Neutron star structure.
• Computational issues: Schroedinger equation on the lattice
• Time dependent density functional theory for superfluid systems
