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…
