21. Ultracold atoms in optical potentials : from noise-induced transport to superfluidity
Abstract : In this thesis, both experimental studies and numerical simulations of ultracold atoms in optical potentials are presented in a collection of nine scientific papers. In particular, noise-induced transport in dissipative optical lattices and superfluid properties of Bose-Einstein condensates have been studied. READ MORE

22. Excitations in Superfluids : From solitons to gravitational waves
Abstract : In 1995 two different research groups observed for the first time the Bose-Einstein condensation (BEC) in ultracold gases. When the confining magnetic trap was turned off the gas was left free to expand, and the velocity of the particles showed a clear peak: most of the particles were occupying the same single particle state, the one of lowest energy.

23. Multi-species systems in optical lattices : From orbital physics in excited bands to effects of disorder
Abstract : In this thesis we explore different aspects of the physics of multi-species atomic systems in optical lattices. In the first part we will study cold gases in the first and second excited bands of optical lattices - the p and d bands. READ MORE

24. Abelian and non-abelian quantum Hall hierarchies
Abstract : A core tenet of condensed matter physics has been that different phases of matter can be classified according to Landau's symmetry breaking paradigm. It has become clear, however, that phases of matter exist that are not distinguished by symmetry, but rather by topology. READ MORE

25. Many-photon effects in time-resolved second harmonic generation from systems in optical cavities
Abstract : Second harmonic generation is popular due to its numerous applications in different technologies dealing with multiple fields of science. The rapid technical advancement with the second harmonic generation demands parallel development in the theoretical understanding. READ MORE
