On the bosonic behavior of mean-field fluctuations in atomic ensembles
Michael Keyl, Dirk-Michael Schlingemann, Zoltan Zimboras
The mean field fluctuations of large atomic ensembles can behave like bosonic modes, i.e. they induce a state on an appropriate system of bosonic modes. The most prominent example…

Entanglement entropy in quantum spin chains with broken reflection symmetry
Zoltan Kadar, Zoltan Zimboras
We investigate the entanglement entropy of a block of L sites in quasifree translation-invariant spin chains concentrating on the effect of reflection symmetry breaking. The majora…
