Dynamic mean-field theory for dense spin systems at infinite temperature
Timo Gräßer, Philip Bleicker, Dag-Björn Hering +2
A dynamic mean-field theory for spin ensembles (spinDMFT) at infinite temperatures on arbitrary lattices is established. The approach is introduced for an isotropic Heisenberg mode…

Charge dynamics in magnetically disordered Mott insulators
Philip Bleicker, Dag-Björn Hering, Götz S. Uhrig
With the aid of both a semi-analytical and a numerically exact method we investigate the charge dynamics in the vicinity of half-filling in the one- and two-dimensional - mod…
