Current research topics
A classical physicist by training, I worked about chaos/nonlineairity/stochasticity until the fall of 2006.
Then I felt that the life at the classical corner has become boring. A brave new quantum world opened up to me and
I am on quantum tracks since then.
- ac-driven quantum systems
Our proposal for ac-driven quantum ratchets with
ultracold atoms (BEC) [23, 24] has been incarnated by the group of Martin Weitz
(Science 326, 1241 (2009)) . They observed a whole spectrum of theoretically
predicted effects and thus demarcated their quantum ratchet
from classical ones.
Quantum Machinery
- many-body quantum systems out of equilibrium
Excitations/energy/entalgement propagation mechanisms, stationary
nonequilibrium states.
- interaction between finite quantum systems
Energy/information exchange, "embracing" through classical and
quantum correlations (entanglement), nonequlibrium states and relaxation to
equilibrium [36, 37].
