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…
Probing thermalization in quenched (non-)integrable Fermi-Hubbard models
Philip Bleicker, Joachim Stolze, Götz S. Uhrig
Using numerically exact methods we examine the Fermi-Hubbard model on arbitrary cluster topology. We focus on the question which systems eventually equilibrate or even thermalize a…
Strong quenches in the one-dimensional Fermi-Hubbard model
Philip Bleicker, Götz S. Uhrig
The one-dimensional Fermi-Hubbard model is used as testbed for strong global parameter quenches. With the aid of iterated equations of motion in combination with a suitable scalar…
Persisting correlations of a central spin coupled to large spin baths
Urban Seifert, Philip Bleicker, Philipp Schering +2
The decohering environment of a quantum bit is often described by the coupling to a large bath of spins. The quantum bit itself can be seen as a spin which is commonly call…
