Instability of Bose-Einstein condensation on quantum graphs under repulsive perturbations
Jens Bolte, Joachim Kerner
In this Note we investigate Bose-Einstein condensation in interacting quantum many-particle systems on graphs. We extend previous results obtained for particles on an interval and…

Bose-Einstein condensation on quantum graphs
Jens Bolte, Joachim Kerner
We present results on Bose-Einstein condensation (BEC) on general compact quantum graphs, i.e., one-dimensional systems with a (potentially) complex topology. We first investigate…
