We study a variety of topics in theoretical condensed matter physics related to superconductivity, quantum and atom optics, as well as mesoscopic physics. Our main interest in superconductors is with its phenomenological aspects, vortex matter, pinning, disordered systems. Within the domain of quantum optics, we are interested in the structural competition in dipolar gases with its rich structure, in particular, new tunable solitonic phases in two dimensions. Strongly correlated photons in hybrid (cavity, qubit) devices (cavity QED) define a multi-faceted system, allowing to study a wide range of phenomena from new bulk photonic phases in extended cavity arrays to mesoscopic aspects (photon transport, photon blockade) in few cavity systems. Our main interest in electronic mesoscopic systems is in the interplay of single-particle transport, interactions, entanglement, and wave-packet resurrection providing a strategy to enhance the coherence time in these systems. Applications in quantum information processing remain a topic of continuous interest.
