Fock State Sampling Method -- Characteristic temperature of maximal fluctuations for interacting bosons in box potentials
M. B. Kruk, T. Vibel, J. Arlt +3
We study the statistical properties of a gas of interacting bosons trapped in a box potential in two and three dimensions. Our primary focus is the characteristic temperature $\tch…
Microcanonical and Canonical Fluctuations in Bose-Einstein Condensates -- Fock state sampling approach
Maciej Bartłomiej Kruk, Dawid Hryniuk, Mick Kristensen +4
The fluctuations of the atom number between a Bose-Einstein condensate and the surrounding thermal gas have been the subject of a long standing theoretical debate. This discussion…
Breathing Mode of a Bose-Einstein Condensate Immersed in a Fermi Sea
Piotr T. Grochowski, Tomasz Karpiuk, Mirosław Brewczyk +1
By analyzing breathing mode of a Bose-Einstein condensate repulsively interacting with a polarized fermionic cloud, we further the understanding of a Bose-Fermi mixture recently re…
Collective oscillations of a two-component Fermi gas on the repulsive branch
Tomasz Karpiuk, Piotr T. Grochowski, Mirosław Brewczyk +1
We calculate frequencies of collective oscillations of two-component Fermi gas that is kept on the repulsive branch of its energy spectrum. Not only is a paramagnetic phase explore…
Many-body soliton-like states of the bosonic ideal gas
Rafał Ołdziejewski, Wojciech Górecki, Krzysztof Pawłowski +1
We study the lowest energy states for fixed total momentum, i.e. yrast states, of bosons moving on a ring. As in the paper of A. Syrwid and K. Sacha \cite{syrwid2015} , we comp…
Bose statistics and classical fields
Emilia Witkowska, Mariusz Gajda, Kazimierz Rzążewski
Classical fields counterpart of the ideal Bose gas statistics in a trap is investigated by performing calculations in the canonical ensemble. There exists the optimal cut-off which…
