Multiplet effects in orbital and spin ordering phenomena: A hybridization-expansion quantum impurity solver study
Andreas Flesch, Evgeny Gorelov, Erik Koch +1
Orbital and spin ordering phenomena in strongly correlated systems are commonly studied using the local-density approximation + dynamical mean-field theory approach. Typically, how…
Orbital-order melting in rare-earth manganites: the role of super-exchange
Andreas Flesch, Guoren Zhang, Erik Koch +1
We study the mechanism of orbital-order melting observed at temperature T_OO in the series of rare-earth manganites. We find that many-body super-exchange yields a transition-tempe…
Probing the relaxation towards equilibrium in an isolated strongly correlated 1D Bose gas
Stefan Trotzky, Yu-Ao Chen, Andreas Flesch +4
The problem of how complex quantum systems eventually come to rest lies at the heart of statistical mechanics. The maximum entropy principle put forward in 1957 by E. T. Jaynes sug…
Probing local relaxation of cold atoms in optical superlattices
A. Flesch, M. Cramer, I. P. McCulloch +2
In the study of relaxation processes in coherent non-equilibrium dynamics of quenched quantum systems, ultracold atoms in optical superlattices with periodicity two provide a very…
Exploring local quantum many-body relaxation by atoms in optical superlattices
M. Cramer, A. Flesch, I. P. McCulloch +2
We establish a setting - atoms in optical superlattices with period 2 - in which one can experimentally probe signatures of the process of local relaxation and apparent thermalizat…
