DESCRIPTION:Title: <a href="https://researchseminars.org/talk/PSMQFT/13/">
 A new approach to the hard-core Bose gas</a>\nby Morris Brooks (University
  of Zürich) as part of Probability\, Statistical Mechanics and Quantum Fi
 elds\n\n\nAbstract\nIn this talk I will present a recent result on the gro
 und-state energy of a Bosonic quantum gas with hard-core interactions (bil
 liard balls)\, which proves the missing upper bound in the Lee-Huang-Yang 
 formula. While this result settles a substantial open problem in the field
 \, I want to put an emphasize on the genuinely novel methods used within. 
 In the proof\, we are naturally led to the study of a classical gas\, whos
 e probability distribution we characterize using the language of second qu
 antization. In particular\, I want to provide a perspective on the impact 
 of our result beyond the boundaries of quantum mechanics.\n
