Quantum energy and coherence exchange with discrete baths

Galiceanu, M.; Beims, M.W.; Strunz, W.T. - In: Physica A: Statistical Mechanics and its Applications 415 (2014) C, pp. 294-306

Coherence and quantum average energy exchange are studied for a system particle as a function of the number N of constituents of a discrete bath model. The time evolution of the energy and coherence, determined via the system purity (proportional to the linear entropy of the quantum statistical...

Bipartite entanglement induced by classically-constrained quantum dissipative dynamics

Budini, Adrián A. - In: Physica A: Statistical Mechanics and its Applications 392 (2013) 19, pp. 4638-4651

The properties of some complex many body systems can be modeled by introducing in the dissipative dynamics of each single component a set of kinetic constraints that depend on the state of the neighbor systems. Here, we characterize this kind of dynamics for two quantum systems whose independent...

Partial entropy creation of a two-level atom with intrinsic decoherence

Zidan, Nour - In: Physica A: Statistical Mechanics and its Applications 391 (2012) 1, pp. 401-409

influence of intrinsic decoherence and Stark shift on the partial entropy change and the entanglement. It is shown that, quality … of the partial entropy is improved significantly by introducing the intrinsic decoherence and(or)Stark shift. In addition … influences of intrinsic decoherence and Stark shift is also presented. …
