Title: Decoherent dynamics of two nonclassically correlated particles

Abstract

We investigate the dynamics of nonclassical correlations between two particles in a harmonic trap which interact in a pointlike manner. Via a quantum-jump approach we add a specific damping model. The correlations between the particles are quantified using a Bell-type correlation function, adapted for the continuous-variable case. They clearly exceed the classical border and show collapses and revivals. Their destruction due to decoherence strongly depends on the initial separation of the particles and on the damping constant.
