On the spectral gap of one-dimensional Schrödinger operators on large intervals
Joachim Kerner, Matthias Täufer
We study the effect of non-negative potentials on the spectral gap of one-dimensional Schrödinger operators in the limit of large intervals. In particular, we derive upper and lowe…

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…
