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

Atomic Bose-Einstein condensation with three-body interactions and collective excitations
TL;DR: In this article, the Ginzburg-Pitaevskii-Gross (GPG) nonlinear Schrequation is extended to include an effective potential dependent on the square of the density and solved numerically for the s-wave.

Computational Multiscale Modeling of Fluids and Solids
TL;DR: In this paper, the authors provide a sound mathematical background of many abstract concepts prevalently used in physical theories, such as tensors and manifolds, which are important mathematical tools for a succinct and precise formulation of physical theories.

Fluctuations of Bose-Einstein Condensate
TL;DR: In this article, the ground state occupation number and its fluctuations for the Bose-Einstein condensate of trapped atoms using the microcanonical ensemble were analyzed using the saddle point method.
