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…

Josephson effect between superconducting nanograins with discrete energy levels
Dominique Gobert, Ulrich Schollwock, Jan von Delft
We investigate the Josephson effect between two coupled superconductors, coupled by the tunneling of pairs of electrons, in the regime that their energy level spacing is comparable…
