Stochastic efficiency: five case studies

New Journal of Physics, 2015
Stochastic efficiency is evaluated in five case studies: driven Brownian motion, effusion with a thermo-chemical and thermo-velocity gradient, a quantum dot and a model for information to work conversion.

Geometric effect and gauge field in nonequilibrium quantum thermostatistics

, 2005
The concept of work is studied in quantum thermostatistics of a system surrounded by an environment and driven by an external force. It is found that there emerges the gauge theoretical structure in a nonequilibrium process, the field of which is ...

Clustering in N-Body gravitating systems

, 2001
Self-gravitating systems have acquired growing interest in statistical mechanics, due to the peculiarities of the 1/r potential. Indeed, the usual approach of statistical mechanics cannot be applied to a system of many point particles interacting with ...

Validity of the second law in nonextensive quantum thermodynamics

, 2003
The second law of thermodynamics in nonextensive statistical mechanics is discussed in the quantum regime. Making use of the convexity property of the generalized relative entropy associated with the Tsallis entropy indexed by q, Clausius' inequality is ...

Macroscopic thermodynamics of equilibrium characterized by power-law canonical distributions

, 2000
Macroscopic thermodynamics of equilibrium is constructed for systems obeying power-law canonical distributions. With this, the connection between macroscopic thermodynamics and microscopic statistical thermodynamics is generalized.

Robustness of the second law of thermodynamics under generalizations of the maximum entropy method

, 2007
It is shown that the laws of thermodynamics are extremely robust under generalizations of the form of entropy. Using the Bregman-type relative entropy, the Clausius inequality is proved to be always valid.

A Rotating Charged Black Hole Solution in f(R) Gravity

, 2011
In the context of f(R) theories of gravity, we address the problem of finding a rotating charged black hole solution in the case of constant curvature.

Sobre el parámetro de no extensividad para algunos sistemas super-aditivos

Ingeniería y Ciencia, 2010
Este artículo propone una relación biunívoca entre el parámetro de no extensividad q y la función de densidad de probabilidad estacionaria f correspondientes a un observable u para algunos sistemas super–aditivos en los que la Entropía de Tsallis sea ...

Comportamiento de 33 accesiones de café (Coffea sp.) tipo Catimor en San Ramón, Chanchamayo, Perú

Revista de Investigación e Innovación Agropecuaria y de Recursos Naturales
El café se cultiva en el Perú, hace más de 100 años, y desde entonces, se introdujeron diversas variedades comerciales, mayormente de manera informal, aunque este accionar está cambiado en los últimos años, para bien de la caficultura nacional.

Unnormalized nonextensive expectation value and zeroth law of thermodynamics

, 2001
We show an attempt to establish the zeroth law of thermodynamics within the framework of nonextensive statistical mechanics based on the classic normalization $\texttt{Tr}\hat{\rho}=1$ and the unnormalized expectation $x=\texttt{Tr}\hat{\rho}^q\hat{x ...
