Continuous time random walks in closed and open single-molecule systems with microscopic reversibility
– Continuous time random walk (CTRW) is studied with a new dynamic equation based on the age-structure of states. For a CTRW in a closed molecular system, two necessary conditions for microscopic reversibility are introduced: 1) independence of transition direction and waiting time for every state and 2) detailed balance among the transition probabilities. Together they are also sufficient cond...
متن کاملThe Principle of Microscopic Reversibility.
In recent years increasing use has been made of a new postulate which perhaps cannot yet be stated in its final form, but which requires in a general way in the case of a system in thermodynamic equilibrium not only that the total number of molecules leaving a given state in unit time shall on the average equal the number arriving in that state in unit time, but also that the number leaving by ...
متن کاملMicroscopic derivation of open quantum walks
Recently, a formalism for discrete time open quantum walks was introduced [1]. The formalism suggested is similar to the formalism of quantum Markov chains and rests upon the implementation of appropriate completely positive maps. The formalism of the open quantum random walks (OQW) includes the classical random walk and through a physical realization procedure a connection to the unitary quant...
متن کاملOn thermodynamic and microscopic reversibility
The word ‘reversible’ has two (apparently) distinct applications in statistical thermodynamics. A thermodynamically reversible process indicates an experimental protocol for which the entropy change is zero, whereas the principle of microscopic reversibility asserts that the probability of any trajectory of a system through phase space equals that of the time reversed trajectory. However, these...
متن کاملopen quantum systems
Quantum mechanics must be regarded as open systems. On one hand, this is due to the fact that, like in classical physics, any realistic system is subjected to a coupling to an uncontrollable environment which influences it in a non-negligible way. The theory of open quantum systems thus play a major role in many applications of quantum physics since perfect isolation of quantum system is not po...
