Ground-state energy and depletions for a dilute binary Bose gas
Andre Eckardt, Christoph Weiss, Martin Holthaus
When calculating the ground-state energy of a weakly interacting Bose gas with the help of the customary contact pseudopotential, one meets an artifical ultraviolet divergence whic…
Ground state energy of a homogeneous Bose-Einstein condensate beyond Bogoliubov
Christoph Weiss, Andre Eckardt
The standard calculations of the ground-state energy of a homogeneous Bose gas rely on approximations which are physically reasonable but difficult to control. Lieb and Yngvason [P…
Factorising numbers with a Bose-Einstein condensate
Christoph Weiss, Steffen Page, Martin Holthaus
The problem to express a natural number N as a product of natural numbers without regard to order corresponds to a thermally isolated non-interacting Bose gas in a one-dimensional…
Asymptotics of the number partitioning distribution
C. Weiss, M. Holthaus
The number partitioning problem can be interpreted physically in terms of a thermally isolated non-interacting Bose gas trapped in a one-dimensional harmonic oscillator potential.…
