DMRG Studies of Disordered Bosons — •Ulrich Schollwöck — Institut für Theoretische Physik C, RWTH Aachen

The DMRG method has emerged as a very powerful tool to characterize the phase diagrams of strongly interacting one-dimensional systems with disorder, namely in the case of bosons. In this talk I will present various complementary approaches to study disorder effects in bosonic systems and discuss the phase diagram of a disordered Bose-Hubbard model with a box distribution as well as new results related to other forms of disorder distributions.
