Lee-Huang-Yang dynamics emergent from a direct Wigner representation
King Lun Ng, Maciej Bartłomiej Kruk, Piotr Deuar
We demonstrate how the beyond-mean-field Lee-Huang-Yang (LHY) corrections and its related physics can be naturally incorporated into the representation of an ultracold Bose gas usi…
On the fluctuations of the number of atoms in the condensate
Maciej B. Kruk, Piotr Kulik, Malthe F. Andersen +6
Bose-Einstein condensation represents a remarkable phase transition, characterized by the formation of a single quantum subsystem. As a result, the statistical properties of the co…
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…
Observation of Microcanonical Atom Number Fluctuations in a Bose-Einstein Condensate
M. B. Christensen, T. Vibel, A. J. Hilliard +6
Quantum systems are typically characterized by the inherent fluctuation of their physical observables. Despite this fundamental importance, the investigation of the fluctuations in…
Statistical properties of cold bosons in a ring trap
Maciej Kruk, Maciej Łebek, Kazimierz Rzążewski
A study of an interacting system of bosons in a ring trap at a finite temperature is presented. We consider a gas with contact and long-range dipolar interactions within a framewor…
