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

Coherence lifetimes of excitations in an atomic condensate due to the thin spectrum
TL;DR: In this article, the authors studied the quantum coherence properties of a finite-sized atomic condensate using a toy model and the thin spectrum model formalism, and the decoherence time of the ground state was investigated for both zero and finite temperatures.

Einstein's fluctuation formula. A historical overview
TL;DR: In this article, a historical overview on the basic results which appeared by the year 1926 concerning Einstein's fluctuation formula of black-body radiation, in the context of light-quanta and wave-particle duality, is given.
Dissertation
Theory of cold dipolar and toroidal gases
TL;DR: In this paper, a mean-field treatment for dipolar Bose and Fermi gases was proposed, in which exchange effects are described by a local effective potential, which is in excellent agreement with full Hartree-Fock calculations at zero and finite temperature.

Heteronuclear Molecules from a Quantum Degenerate Fermi-Fermi Mixture
TL;DR: In this article, the first quantum degenerate Fermi-fermi mixture with unequal masses was realized in the strongly interacting regime at a s-wave Feshbach resonance.

Bose-Einstein condensation of optically trapped cesium
TL;DR: In this paper, Bose-Einstein condensation of cesium atoms is achieved by evaporative cooling using optical trapping techniques, and the ability to tune the interactions between the ultracold atoms by an external magnetic field offers intriguing features for potential applications.
