Fermion- and spin-counting in strongly correlated systems in and out of thermal equilibrium
Fermion spin-counting correlated systems equilibrium

Atom counting theory can be used to study the role of thermal noise in quantum phase transitions and to monitor the dynamics of a quantum system. We illustrate this for a strongly correlated fermionic...

In a recent paper [M. Huber {\it et al}, Phys. Rev. Lett. {\bf 104}, 210501 (2010)] new criteria to find out the presence of multipartite entanglement have been given. We exploit these tools in order ...
A framework for the investigation of disordered quantum systems in thermal equilibrium is proposed. The approach is based on a dynamical model--which consists of a combination of a double-bracket grad...

It is shown, that Bose-Einstein condensation can occur not only in spatially extended
equilibrium systems, but also in the systems far from thermal equilibrium, which show
order-disorder phase trans...
