We study many-body qunatum phenomena using ultracold atoms and ions in a trap. We are currently conducting two experimental projects: (1) investigation of the thermodynamic properties of atoms with p-wave interactions, (2) cold chemical reactions in an ultracold atom-ion mixture.
We study Bose-Einstein condensates and superfluids theoretically. Our research interest covers qunatum hydrodynamics, spinor and dipolar condensates, collapse and explosion of condensates, and exciton-polariton superfluids.

- Trajectory of a group of ultracold atoms produced by the optical lattice's modulation, exhibited as a function of time and position. Bifurcations due to band gaps.
Novel quantum nature of matter manifests itself at extremely low temperatures. By means of theoretical techniques, we investigate exotic behavior of ultracold fermionic as well as bosonic atoms placed in an optical lattice. We examine the coherent wave packets produced by the lattice’s amplitude modulation, whose controlled motion may be exploited for high precision measurements.
