Quantum Bose-Bose droplets at a dimensional crossover
Paweł Ziń, Maciej Pylak, Tomasz Wasak +2
We study a liquid quantum droplets in a mixture of two-component Bose-Einstein condensates under a variable confinement introduced along one or two spatial dimensions. Despite the…
The influence of interaction between quasiparticles on parametric resonance process in Bose-Einstein condensates
Paweł Ziń, Maciej Pylak
We analyze the uniform system of weakly interacting bosonic gas undergoing periodic oscillation of interaction constant. This, within Bogoliubov approximation, leads to creation of…
Second order quantum phase transition of a homogeneous Bose gas with attractive interactions
P. Ziń, B. Oleś, M. Trippenbach +1
We consider a homogeneous Bose gas of particles with an attractive interaction. Mean field theory predicts for this system a spontaneous symmetry breaking at a certain value of the…
On the infimum of the energy-momentum spectrum of a homogeneous Bose gas
H. D. Cornean, J. Dereziński, P. Ziń
We consider second quantized homogeneous Bose gas in a large cubic box with periodic boundary conditions, at zero temperature. We discuss the energy-momentum spectrum of the Bose g…
