Thermodynamics as Control Theory [PDF]

open access: yes, 2013
I explore the reduction of thermodynamics to statistical mechanics by treating the former as a control theory: a theory of which transitions between states can be induced on a system (assumed to obey some known underlying dynamics) by means of operations

Mechanical Proof of the Second Law of Thermodynamics Based on Volume Entropy [PDF]

open access: yes, 2007
In a previous work (M. Campisi. Stud. Hist. Phil. M. P. 36 (2005) 275-290) we have addressed the mechanical foundations of equilibrium thermodynamics on the basis of the Generalized Helmholtz Theorem.

Time in Thermodynamics [PDF]

open access: yes, 2011
It is often claimed, or hoped, that some temporal asymmetries are explained by the thermodynamic asymmetry in time. Thermodynamics, the macroscopic physics of pressure, temperature, volume, and so on, describes many temporally asymmetric processes.

Gaussian work extraction from random Gaussian states is nearly impossible

open access: yesPhysical Review Research, 2023
Quantum thermodynamics can be naturally phrased as a theory of quantum state transformation and energy exchange for small-scale quantum systems undergoing thermodynamical processes, thereby making the resource theoretical approach very well suited. A key

Probabilistically violating the first law of thermodynamics in a quantum heat engine

open access: yesSciPost Physics, 2022
Fluctuations of thermodynamic observables, such as heat and work, contain relevant information on the underlying physical process. These fluctuations are however not taken into account in the traditional laws of thermodynamics. While the second law is

Nonequilibrium thermodynamics in cavity optomechanics

open access: yesFundamental Research, 2023
Classical thermodynamics has been a great achievement in dealing with systems that are in equilibrium or near equilibrium. As an emerging field, nonequilibrium thermodynamics provides a general framework for understanding the nonequilibrium processes ...

Bluff your Way in the Second Law of Thermodynamics [PDF]

open access: yes, 2001
The aim of this article is to analyse the relation between the second law of thermodynamics and the so-called arrow of time. For this purpose, a number of different aspects in this arrow of time are distinguished, in particular those of time-(a)symmetry ...

Quantum thermodynamically consistent local master equations

open access: yesPhysical Review Research, 2021
Local master equations are a widespread tool to model open quantum systems, especially in the context of many-body systems. These equations, however, are believed to lead to thermodynamic anomalies and violation of the laws of thermodynamics. In contrast,

Entropy Exchange and Thermodynamic Properties of the Single Ion Cooling Process

open access: yesEntropy, 2019
A complete quantum cooling cycle may be a useful platform for studying quantum thermodynamics just as the quantum heat engine does. Entropy change is an important feature which can help us to investigate the thermodynamic properties of the single ion ...
