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

Jeans instability and turbulent gravitational collapse of Bose-Einstein Condensate dark matter halos.
TL;DR: In this paper, the Jeans instability and the gravitational collapse of the rotating Bose-Einstein Condensate dark matter halos, described by the zero temperature non-relativistic Gross-Pitaevskii equation, with repulsive interparticle interactions, are considered.
Analysis of a trapped atom clock with losses
TL;DR: In this paper, the authors present a number of analytical means for the analysis of the evolution of an atom clock, emphasizing the role of many-body processes in the population and coherence loss.

D-dimensional Bose gases and the Lambert W function
TL;DR: In this paper, the Lambert W function is used to express the condensate temperature, TC, in terms of the number of particles N; in 2D and 3D Bose gases, T can be expressed in terms both P and μ through the W function.

The nonlinear Schrödinger equation: A mathematical model with its wide-ranging applications
TL;DR: The nonlinear Schrodinger equation (NLSE) as mentioned in this paper is one example of integrable systems of a nonlinear partial differential equation in $(1 + 1)$D and possesses an infinite set of conservation laws.

Towards interferometry with bright solitary waves in a ring
TL;DR: In this article, the splitting of a bright solitary wave, which is created from a 85Rb Bose-Einstein condensate in an optical waveguide, is realized through scattering from a narrow potential well formed from a tightly focussed red detuned laser beam.
