Non-Markovian Dynamics and Entanglement in Quantum Brownian Motion
Dynamical aspects of quantum Brownian motion at low temperatures are investigated. Exact calculations of quantum entanglement among two Brownian oscillators are given without invoking the Born-Markov or Born approximation widely used for the study of open systems. Our approach is applicable for arbitrary time scale, in particular, suitable to probe short time regime at cold temperatures where m...

متن کاملEntanglement oscillations in non-Markovian quantum channels
We study the non-Markovian dynamics of a two-mode bosonic system interacting with two uncorrelated thermal bosonic reservoirs. We present the solution to the exact microscopic Master equation in terms of the quantum characteristic function and study in details the dynamics of entanglement for bipartite Gaussian states. In particular, we analyze the effects of short-time system-reservoir correla...

متن کاملQuantum Entanglement under Lorentz Boost
In order to understand the characteristics of quantum entanglement of massive particles under Lorentz boost, we first introduce a relevant relativistic spin observable, and evaluate its expectation values for the Bell states under Lorentz boost. Then we show that maximal violation of the Bell’s inequality can be achieved by properly adjusting the directions of the spin measurement even in a rel...
