Maths HEP Lunchtime Seminars: How Many is Different? Ideal Bose gas revisited

Presented by Jeong-Hyuck Park , Sogang University

6 July 2011 11:00 in E102

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 gas zigzags on the
temperature-volume plane provided the number of particles is finitely large
enough. This demonstrates for the first time, how finite systems can feature
mathematical singularities. The talk is based on papers: Phys. Rev. A 81
063636 (2010) and New J. Phys. 13 (2011) 033003.
