Thermal Area Law for Lattice Bosons
Marius Lemm, Oliver Siebert
A physical system is said to satisfy a thermal area law if the mutual information between two adjacent regions in the Gibbs state is controlled by the area of their boundary. Therm…

Bose-Einstein condensation on hyperbolic spaces
Marius Lemm, Oliver Siebert
A well-known conjecture in mathematical physics asserts that the interacting Bose gas exhibits Bose-Einstein condensation (BEC) in the thermodynamic limit. We consider the Bose gas…
