How Many is Different? Ideal Bose gas revisited
Jeong-Hyuck Park (Sogang University, Seoul)
Thursday 05 July 2012 14:00 -  Tours -  Salle 1180 (Bât E2)

Résumé :
We revisit the ideal Bose gas confined in a cubic box, which is discussed in most of statistical physics textbooks as the simplest bosonic system. We report that, the isobar of the ideal gas zigzags on the temperature-volume plane provided the number of particles is finitely large enough. This may demonstrate for the first time, how finite systems can feature mathematical singularities, realizing the notion of `Emergence'.
