Abstract A covariant way to define the relativistic entropy of a finite object has been proposed. The energy–momentum in a finite volume is not a covariant physical entity because of the relativity of simultaneity. A way to correctly handle this situation is introduced and applied to the calculation of entropy. The result together with van Kampen–Israel theory gives simple and self-consistent relativistic thermodynamics. 
Relativistic Energy-Momentum of a Body with a Finite Volume
The problem of energy-momentum in a body with a finite volume has been causing confusion in the theory of relativity, especially in relativistic thermodynamics. Its correct understanding has beenExpand
Relativistic Statistical Mechanics vs. Relativistic Thermodynamics
Based on a covariant theory of equilibrium Thermodynamics, a Statistical Relativistic Mechanics is developed for the non-interacting case and a proposal for a Relatvistic Statistical Mechanics is exposed for the interacting case. Expand
Relativistic Statistical Mechanics with Angular Momentum
The equilibrium distribution function of a relativistic ideal gas has been derived to include the effect of angular momentum. The result agrees with the one obtained from kinetic theory, andExpand
Redefined relativistic thermodynamics based on the Nakamura formalism
By using the concept of volume introduced by Nakamura in relativistic thermodynamics, a relativistic thermodynamical theory is proposed. A comparison is presented between the new theory, the vanExpand
Relativistic Brownian Motion
Stimulated by experimental progress in high energy physics and astrophysics, the unification of relativistic and stochastic concepts has re-attracted considerable interest during the past decade.Expand
The 2.7 K black-body radiation background reference frame
This paper reports that the directional temperature is used to present a scheme for deducing the velocity of the reference frame where the black-body which produces the 2.7 K radiation background isExpand
QM theory of the thermal electron gyroradius
The average (thermal) gyroradius of charged par- ticles is re-examined from a quantum-mechanical point of view. The straight quantum-mechanical calculation clearly reproduces its conventionally usedExpand
Some considerations on quantum computing at sub-atomic scales and its impact in the future of Moore's law
The conclusion is that miniaturization is no longer a reliable answer for the future development of computer science, but instead lateralization is the correct approach and it is proposed that the predicted lateralization-driven evolution in computer science will not be based in quantum computers, but rather in classical computers.

Thermodynamics of relativistic systems
This paper will review recent progress in the covariant formulation of thermodynamics and statistical mechanics, with emphasis on two topics: (i) a consistent treatment of transient effects whichExpand
Nonstationary irreversible thermodynamics: A Causal relativistic theory
Abstract Conventional theories of irreversible thermodynamics predict instantaneous propagation of thermal and viscous effects. This defect can be traced to the omission of terms quadratic in theExpand
Lorentz Transformation of Thermodynamic Quantities
In this paper we review the recent controversy concerning relativistic thermodynamics. The diversity of viewpoints can be attributed to the numerous ways in which thermodynamic quantities areExpand
Physical Quantities in Different Reference Systems According to Relativity
The relativistic transformation of measurements from one observer S to another observer S′ is valid, of course, only when both observers are measuring the same physical quantity. What is the sameExpand
Variation of local heat energy and local temperatures under Lorentz transformations
Abstract If one defines in all inertial frames S the local heat energy Q and the local temperature T, in terms of specific collective variables which describe internal isotropic chaotic motions it isExpand
The Theory of Relativity
THE earlier portion of Dr. Carmichael's book is a reprint of the first edition, which received notice in NATURE for March 12, 1914. The later pages, which are grouped together under one large chapterExpand
