Spin gases as microscopic models for non-Markovian decoherence
L. Hartmann, J. Calsamiglia, W. Dür +1
We analyze a microscopic decoherence model in which the total system is described as a spin gas. A spin gas consists of N classically moving particles with additional, interacting…

Entanglement and decoherence in spin gases
J. Calsamiglia, L. Hartmann, W. Dür +1
We study the dynamics of entanglement in spin gases. A spin gas consists of a (large) number of interacting particles whose random motion is described classically while their inter…

A computable measure of nonclassicality for light
J. K. Asbóth, J. Calsamiglia, H. Ritsch
We propose the Entanglement Potential (EP) as a measure of nonclassicality for quantum states of a single-mode electromagnetic field. It is the amount of two-mode entanglement that…
