Quantum thermodynamics: thermodynamics at the nanoscale [PDF]
Journal of Modern Optics, 2004 A short introduction on quantum thermodynamics is given and three new topics are discussed: 1) Maximal work extraction from a finite quantum system. The thermodynamic prediction fails and a new, general result is derived, the ``ergotropy''.

Thermodynamic potentials and thermodynamic relations in nonextensive thermodynamics [PDF]
Physica A: Statistical Mechanics and its Applications, 2011 The generalized Gibbs free energy and enthalpy is derived in the framework of nonextensive thermodynamics by using the so-called physical temperature and the physical pressure. Some thermodynamical relations are studied by considering the difference between the physical temperature and the inverse of Lagrange multiplier.

Algorithmic thermodynamics [PDF]
Mathematical Structures in Computer Science, 2012 Algorithmic entropy can be viewed as a special case of the entropy studied in statistical mechanics. This viewpoint allows us to apply many techniques developed for use in thermodynamics to the subject of algorithmic information theory. In particular, suppose we fix a universal prefix-free Turing machine and letXbe the set of programs that halt for ...

Thermodynamics Far from the Thermodynamic Limit [PDF]
The Journal of Physical Chemistry B, 2017 Understanding how small systems exchange energy with a heat bath is important to describe how their unique properties can be affected by the environment. In this contribution, we apply Landsberg's theory of temperature-dependent energy levels to describe the progressive thermalization of small systems as their spectrum is perturbed by a heat bath.
