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…

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…
