Abstract
A generalized Born-Markov master equation for describing inelastic tunneling under non-equilibrium interaction is recommended. Rate equations are extracted and analyzed for reaching maximization in tunneling rates. Possible rooms for reviving quantum coherence despite the role of the environment have been surveyed. The scheme extended in this article can provide a general framework for the analysis of quantum tunneling in different realms of quantum optics and quantum biology. It is shown how the non-equilibrium character of the system-environment interaction may strengthen the chance of predominance probability of occurrence of inelastic tunneling against elastic tunneling despite the usual expectation.

Abstract
A quantum demon is a thought experiment in quantum mechanics that describes a hypothetical being that can manipulate individual quantum states, violating the second law of thermodynamics. It is shown how the interaction-free measurement of the observers on a macroscopic thermal field, can make a superposition of cat states even at high-temperature limits. The ability of Alice and Bob to reduce the entropy of the fields without disturbing it directly is surveyed. Then, they can act as quantum demons. Investigation of making cat states under non-equilibrium conditions and the change in the Heisenberg uncertainty relation has been surveyed. Finally, we have also introduced the temperature-dependent Bell’s inequality and studied the change in the limit of violation according to the non-equilibrium character of the dynamics.
