Quantum phase transition in a 1D transport model with boson affected hopping: Luttinger liquid versus charge-density-wave behavior
S. Ejima, G. Hager, H. Fehske
We solve a very general two-channel fermion-boson model describing charge transport within some background medium by means of a refined pseudo-site density matrix renormalization g…

Metallicity in the half-filled Holstein-Hubbard model
H. Fehske, G. Hager, J. Jeckelmann
We re-examine the Peierls insulator to Mott insulator transition scenario in the one-dimensional Holstein-Hubbard model where, at half-filling, electron-phonon and electron-electro…

Data access optimizations for highly threaded multi-core CPUs with multiple memory controllers
Georg Hager, Thomas Zeiser, Gerhard Wellein
Processor and system architectures that feature multiple memory controllers are prone to show bottlenecks and erratic performance numbers on codes with regular access patterns. Alt…
