Stochastic thermodynamics, fluctuation theorems and molecular machines.
Stochastic thermodynamics as reviewed here systematically provides a framework for extending the notions of classical thermodynamics such as work, heat and entropy production to the level of individual trajectories of well-defined non-equilibrium ensembles. It applies whenever a non-equilibrium process is still coupled to one (or several) heat bath(s) of constant temperature. Paradigmatic syste...
متن کاملThermodynamics of stochastic Turing machines
In analogy to Brownian computers we explicitly show how to construct stochastic models which mimic the behavior of a general-purpose computer (a Turing machine). Our models are discrete state systems obeying a Markovian master equation, which are logically reversible and have a well-defined and consistent thermodynamic interpretation. The resulting master equation, which describes a simple one-...
متن کاملFluctuation theorem, nonequilibrium work, and molecular machines
We could paraphrase Professor Noyori [1] and say that the science of molecular machines is four-dimensional chemistry since their 3D structure (x, y, z) is coupled to their motion and kinetics (t). In condensed phases at equilibrium, the motion is erratic with equal probabilities of moving forward or backward according to the principle of detailed balance. Therefore, unidirectional motion is po...
متن کاملThermodynamics and fluctuation theorems for a strongly coupled open quantum system: an exactly solvable case
We illustrate recent results concerning the validity of the work fluctuation theorem in open quantum systems (Campisi et al 2009 Phys. Rev. Lett. 102 210401), by applying them to a solvable model of an open quantum system. The central role played by the thermodynamic partition function of the open quantum system, a two-level fluctuator with a strong quantum nondemolition coupling to a harmonic ...
متن کاملRelativistic Fluctuation Theorems
= 1, is derived which holds simultaneously with the first relation and where ∆h is proportional to the Hubble constant. Furthermore, the fluctuation theorems are shown to provide a physical criterion to resolve the known discretization dilemma arising in special-relativistic Brownian motion. Explicit examples and a general method for the computation of non-Gaussian entropy fluctuations are prov...
