Ground state energy of a dilute two-dimensional Bose gas from the Bogoliubov free energy functional
arXiv:1903.09268 · doi:10.1063/1.5096987
Abstract
We extend the analysis of the Bogoliubov free energy functional to two dimensions at very low temperatures. For sufficiently weak interactions, we prove two term asymptotics for the ground state energy.
