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

Bose-Einstein Condensates in a Single Double Well Potential
TL;DR: In this article, the experimental implementation of a single bosonic Josephson junction and the discussion of the performed investigations are discussed, where two dynamical regimes can be identified, the plasma oscillation regime, where atoms tunnel back and forth between the double well potential into two matter wave packets, which are coupled coherently to each other via quantum mechanical tunneling of atoms through the barrier.

⁸⁷Rubidium Bose-Einstein condensates : machine construction and quantum Zeno experiments
TL;DR: In this article, Ketterle et al. showed that the suppression of the transition rate in the two level system was quantified for pulsed measurements with a time between pulses δt and weak continuous measurements with scattering rate γ, which is in agreement with the previously predicted value of 4.60(0.43).

TL;DR: In this article, the numerical approximation of low-energy eigenstates of the linear random Schrodinger operator was studied under oscillatory high-amplitude potentials with a sufficient degree of disorder.
