On Bose-Einstein condensation in one-dimensional noninteracting Bose gases in the presence of soft Poisson obstacles
Maximilian Pechmann
We study Bose-Einstein condensation (BEC) in one-dimensional noninteracting Bose gases in Poisson random potentials on with single-site potentials that are nonnegative,…
On a condition for type-I Bose-Einstein condensation in random potentials in dimensions
Joachim Kerner, Maximilian Pechmann, Wolfgang Spitzer
In this paper we discuss Bose-Einstein condensation (BEC) in systems of pairwise non-interacting bosons in random potentials in dimensions. Working in a rather general framewor…
On Bose-Einstein condensation in the Luttinger-Sy model with finite interaction strength
Joachim Kerner, Maximilian Pechmann, Wolfgang Spitzer
We study Bose-Einstein condensation (BEC) in the Luttinger-Sy model. Here, Bose point particles in one spatial dimension do not interact with each other, but, through a positive (r…
Bose--Einstein condensation in the Luttinger--Sy model with contact interaction
Joachim Kerner, Maximilian Pechmann, Wolfgang Spitzer
We study bosons on the real line in a Poisson random potential (Luttinger--Sy model) with contact interaction in the thermodynamic limit at absolute zero temperature. We prove that…
