Correlations in a band insulator
Michael Sentef, Jan Kunes, Philipp Werner +1
We study a model of a covalent band insulator with on-site Coulomb repulsion at half-filling using dynamical mean-field theory. Upon increasing the interaction strength the system…

Spin transport in Heisenberg antiferromagnets
Michael Sentef, Marcus Kollar, Arno P. Kampf
We analyze spin transport in insulating antiferromagnets described by the XXZ Heisenberg model in two and three dimensions. Spin currents can be generated by a magnetic-field gradi…
