One exemplary investigation we carried out recently in Quantum thermodynamics field is whether quantum entanglement can be maintained up to some high temperatures. We compare the case of a model system S of two coupled oscillators interacting with a common thermal bath [4-6,7] with the case when each oscillator is coupled to its own bath, kept at different temperatures [8]. Our present study of quantum systems with bilinear and time-independent coupling 1) proves the existence of a NESS by considering the heat transfer in the total system-environment complex [9] and 2) compares the entanglement at high temperatures between a system a) in equilibrium, and b) under the NESS condition. These studies serve to discern the true physical causes of a system’s ability to sustain quantum entanglement at high temperatures, if at all.
