Finite-time quantum thermodynamic processes

The European Physical Journal Special Topics, 2007
We study a single quantum object subject to a parametrized distortion of its discrete spectrum and to a parametrized change of its state, which remains diagonal in its invariant energy eigenbasis. The Carnot and the Otto cycle are investigated in the quasistatic as well as in the dynamic (finite time) regime.

Finite-time thermodynamics. Active potentiostatting

Journal of Physics D: Applied Physics, 1998
The paper addresses minimization of the dissipation in systems maintaining constant temperature or other constant intensive variables (potentiostatted systems). The entropy production and energy consumption of such systems are reduced from those of the traditional scheme if additional chambers are interposed between the system and its surroundings, in ...

Optimization in finite-reservoir finite-time thermodynamics

Physical Review E, 2014
A necessary condition to optimize work output is obtained for general heat engines working between two finite-sized heat reservoirs in a given period of time τ, with the amount of heat received from the hot reservoir being fixed for all possible realizations of the process.

Thermodynamics in finite time. II. Potentials for finite-time processes

Physical Review A, 1977
Within the context of conventional time-independent thermodynamics, an algorithm is developed to construct potentials $\mathcal{P}$ that define the extremal values of work for processes with arbitrary constraints. An existence theorem is proved that demonstrates that such potentials $\mathcal{P}$ can be given for any quasistatic process.

Thermodynamics for processes in finite time

Accounts of Chemical Research, 1984
Thermodynamics serves several functions for chemistry and ita sister sciences and technologies. The first of these historically, and still one of the most important, is the provision of limits on the performance of proceases and devices. The very origins of thermodynamics developed from the creative ways people addressed the problem of how beat to pump

Finite-time thermodynamics and thermodynamic length

Revue Générale de Thermique, 1996
Abstract Finite-time thermodynamics is the extension of traditional thermodyamics to deal with processes which have explicit time or rate dependencies. In doing so the macroscopic measurable description of thermodynamic systems is preserved while irreversibilities, and the hence entropy production, are introduced via empirical rate equations or ...

Current Trends in Finite‐Time Thermodynamics

Angewandte Chemie International Edition, 2011
AbstractThe cornerstone of finite‐time thermodynamics is all about the price of haste and how to minimize it. Reversible processes may be ultimately efficient, but they are unrealistically slow. In all situations—chemical, mechanical, economical—we pay extra to get the job done quickly. Finite‐time thermodynamics can be used to develop methods to limit
