The Excitation Spectrum of the Bose Gas in the Gross-Pitaevskii Regime
arXiv:2001.00497 · doi:10.1142/S0129055X20600065
Abstract
We consider a gas of interacting bosons trapped in a box of side length one in the Gross-Pitaevskii limit. We review the proof of the validity of Bogoliubov's prediction for the ground state energy and the low-energy excitation spectrum. This note is based on joint work with C. Brennecke, S. Cenatiempo and B. Schlein.
