Quantum lattice dynamical effects on the single-particle excitations in 1D Mott and Peierls insulators
H. Fehske, G. Wellein, G. Hager +2
As a generic model describing quasi-one-dimensional Mott and Peierls insulators, we investigate the Holstein-Hubbard model for half-filled bands using numerical techniques. Combini…
Comparative numerical study of Anderson localization in disordered electron systems
Gerald Schubert, Alexander Weisse, Gerhard Wellein +1
Taking into account that a proper description of disordered systems should focus on distribution functions, the authors develop a powerful numerical scheme for the determination of…
Parallelization Strategies for Density Matrix Renormalization Group Algorithms on Shared-Memory Systems
G. Hager, E. Jeckelmann, H. Fehske +1
Shared-memory parallelization (SMP) strategies for density matrix renormalization group (DMRG) algorithms enable the treatment of complex systems in solid state physics. We present…
