One-dimensional density waves of ultracold bosons in an optical lattice
C. Kollath, U. Schollwöck, J. von Delft +1
We investigate the propagation of density-wave packets in a Bose-Hubbard model using the adaptive time-dependent density-matrix renormalization group method. We discuss the decay o…
Real-time dynamics in spin-1/2 chains with adaptive time-dependent DMRG
Dominique Gobert, Corinna Kollath, Ulrich Schollwoeck +1
We investigate the influence of different interaction strengths and dimerizations on the magnetization transport in antiferromagnetic spin-1/2 XXZ-chains. We focus on the real-time…
Well-defined quasiparticles in interacting metallic grains
Dominique Gobert, Moshe Schechter, Ulrich Schollwock +1
We analyze spectral functions of mesoscopic systems with large dimensionless conductance, which can be described by a universal Hamiltonian. We show that an important class of spec…
