Electron Localization in Rydberg States
Jan Mostowski, Joanna Pietraszewicz
We discuss the possibility of localizing an electron in a highly excited Rydberg state. The second-order correlation of emitted photons is the tool for the determination of electro…
Wigner Function for Harmonic Oscillator and The Classical Limit
Jan Mostowski, Joanna Pietraszewicz
The Wigner function is a quantum analogue of the classical joined distribution of position and momentum. As such is should be a good tool to study quantum-classical correspondence.…
Quantum versus classical angular momentum
Jan Mostowski, Joanna Pietraszewicz
Angular momentum in classical and quantum mechanics is carried out beyond textbooks frames. We compare angular distribution of particle position with classical probabilistic approa…
A semiclassical field theory that is freed of the ultraviolet catastrophe
Piotr Deuar, Joanna Pietraszewicz
A more accurate semiclassical theory for ultracold gases is derived, in which the occupation of high energy modes is dynamically constrained to the Bose-Einstein distribution. This…
Complex wave fields in the interacting one-dimensional Bose gas
J. Pietraszewicz, P. Deuar
We study the temperature regimes of the 1d interacting gas to determine when the matter wave (c-field) theory is, in fact, correct and usable. The judgment is made by investigating…
Mesoscopic density grains in the 1d interacting Bose gas from the exact Yang-Yang solution
Joanna Pietraszewicz, Piotr Deuar
Number fluctuations in a one-dimensional Bose gas consist of contributions from many smaller independent localized fluctuations, the density grains. We have derived a set of extend…
