SUMMARY:Bogoliubov Excitations of dilute Bose-Einstein Condensates - Benja
 min Schlein (Universität Zürich)

DESCRIPTION:We consider systems of N bosons confined in a box with volume 
 one and interacting through a potential with <br>short scattering length o
 f the order 1/N (Gross-Pitaevskii regime). We determine the low-energy spe
 ctrum\, i.e. the <br>ground state energy and low-lying excitations\, up to
  errors that vanishes in the limit of large N\, confirming <br>the validit
 y of Bogoliubov&rsquo\;s predictions. This talk is based on joint work wit
 h C. Boccato\, C. Brennecke\, S. Cenatiempo.
