Plancks Gesetz und Lichtquantenhypothese
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

Integrable models for Bose?Einstein condensates in a double-well potential formulated from Holstein?Primakoff transformations
A P Tonel,L H Ymai +1 more
TL;DR: In this article, the authors presented three families of integrable models for Bose-Einstein condensates in a double-well potential which are based on the combination, two by two, of three algebraic realizations of the Lax operator: the bosonic realization and the su(2) and su(1, 1) Holstein-Primakoffrealization.

The Critical Analysis of the Foundations of Statistical Physics. II. the Theory of Photon Gas
TL;DR: In this article, a critical analysis of the generally accepted foundations of theory of photon (quantum) gas is proposed, and the principle of the unity of formal logic and of rational dialectics is the correct methodological basis of the analysis.
