TLDR
In this article, the authors describe how the Phasenraum eines Lichtquants in bezug auf ein gegebenes Volumen wird in „Zellen“ von der Grose h3 aufgeteilt, i.e., the Zahl der moglichen Verteilungen der Lichtquanten einer makroskopisch definierten Strahlung unter diese Zellen liefert die Entropie.Abstract:
Der Phasenraum eines Lichtquants in bezug auf ein gegebenes Volumen wird in „Zellen“ von der Grose h3 aufgeteilt. Die Zahl der moglichen Verteilungen der Lichtquanten einer makroskopisch definierten Strahlung unter diese Zellen liefert die Entropie und damit alle thermodynamischen Eigenschaften der Strahlung.read more

Heuristic Derivation of Blackbody Radiation Laws using Principles of Dimensional Analysis
Gerhard Kramm,Fritz Herbert +1 more
TL;DR: In this article, a generalized form of Wien's displacement law and the blackbody radiation laws of Rayleigh and Jeans, Rayleigh, Wien and Paschen, Thiesen and Planck are derived using principles of dimensional analysis.

Boosting engine performance with Bose–Einstein condensation
TL;DR: In this paper , the performance of an endoreversible Otto cycle operating with a harmonically confined Bose gas as the working medium is analyzed in three regimes: the Bose-Einstein condensate phase, the gas phase, and the phase transition phase.

The evolution of radiation toward thermal equilibrium: A soluble model that illustrates the foundations of statistical mechanics
TL;DR: In this paper, a master equation for the probability distribution that describes the irreversible approach of a quantum model to thermal equilibrium is presented. But it is not shown that the equilibrium probability distribution is proportional to the total number of micro states for a given configuration, in accordance with Boltzmann's fundamental postulate of equal a priori probabilities.
