Anotácia knihy

At extremely low temperatures clouds of bosonic atoms form what is known as a Bose-Einstein condensate. Recently, it has become clear that many different types of condensates -- so called fragmented condensates -- exist. In order to tell whether fragmentation occurs or not, it is necessary to solve the full many-body Schrödinger equation, a task that remained elusive for experimentally relevant conditions for many years. In this thesis the first numerically exact solutions of the time-dependent many-body Schrödinger equation for a bosonic Josephson junction are provided and compared to the §approximate Gross-Pitaevskii and Bose-Hubbard theories. It is thereby shown that the dynamics of Bose-Einstein condensates is far more intricate than what can be anticipated based on these approximations. A conceptual innovation of this thesis are optimal lattice models. It is shown how all quantum lattice models of condensed matter physics that are based on Wannier §functions, e.g. the Bose/Fermi Hubbard model, can be optimized §variationally. This leads to exciting new physics.§
