On the asymptotic behavior of the spectral gap for discrete Schrödinger operators
Matthias Hofmann, Joachim Kerner, Maximilian Pechmann
In this note we elaborate on the asymptotic behavior of the spectral gap of a class of discrete Schrödinger operators defined on a path graph in the limit of infinite volume. We co…
On Bose-Einstein condensation in interacting Bose gases in the Kac-Luttinger model
Chiara Boccato, Joachim Kerner, Maximilian Pechmann
We study interacting Bose gases of dimensions at zero temperature in a random model known as the Kac-Luttinger model. Choosing the pair-interaction between t…
Bose--Einstein condensation for particles with repulsive short-range pair interactions in a Poisson random external potential in
Joachim Kerner, Maximilian Pechmann
We study Bose gases in dimensions, , with short-range repulsive pair interactions, at positive temperature, in the canonical ensemble and in the thermodynamic limit. W…
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 the effect of repulsive interactions on Bose-Einstein condensation in the Luttinger-Sy model
Joachim Kerner, Maximilian Pechmann
In this paper we investigate the effect of repulsive pair interactions on Bose-Einstein condensation in a well-established random one-dimensional system known as the Luttinger-Sy m…
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…
