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

Frictionless decompression in minimum time of Bose-Einstein condensates in the Thomas-Fermi regime
Dionisis Stefanatos,Jr-Shin Li +1 more
TL;DR: In this paper, a fast adiabatic-like expansion of a one-dimensional Bose-Einstein condensate (BEC) in the Thomas-Fermi regime confined in a harmonic potential is studied.

What Can We Learn From Analogue Experiments
TL;DR: In 2016 Steinhauer reported the experimental observation of quantum Hawking radiation and its entanglement in a Bose-Einstein condensate analogue black hole as mentioned in this paper, which can provide evidence of novel phenomena such as black hole Hawking radiation.
1000 times closer to a continuous atom laser: Steady-state strontium with unity phase-space density
TL;DR: This thesis describes the Strontium Continuous Atom Laser (SrCAL) machine that was built and the many lessons learned, and the technical detail needed for future users of SrCAL to wield this tool with mastery.

Asymptotic description of Dirac mass formation in kinetic equations for quantum particles
TL;DR: In this article, the detailed asymptotic behavior of the solutions of a kinetic equation for quantum particles is studied and it is shown that this behaviour is sensitive not only to the total mass of the initial data but also to its precise behaviour near the origin.

Nonclassicality in an atom–molecule Bose–Einstein condensate: Higher-order squeezing, antibunching and entanglement
TL;DR: In this paper, the transient quantum statistical properties of the atoms and molecules in an atom-molecule BEC system are investigated by obtaining a third-order perturbative solution of the Heisenberg's equations of motion corresponding to the Hamiltonian of the system, where two atoms can collide to form a molecule.
