Critical point influenced by Bose-Einstein condensation

A system of bosons studied within the mean-field framework has two fascinating phenomena: a liquid-gas first order phase transition and Bose-Einstein condensation. Interplay between these two phenomena is being investigated. Depending on the mean-field potential parameters one can observe two types of critical points, called Boltzmann and Bose, that belong to different universality classes with distinct sets of critical exponents. As examples of Bose and Boltzmann CPs pion and alpha matter are considered, respectively. In general, the phase diagram can have one of the CPs or both of them.

Automated summary

A system of bosons studied within the mean-field framework exhibits two fascinating phenomena: a first order liquid-gas phase transition and Bose-Einstein condensation. The interplay between these two phenomena is currently being investigated, with the existence of two types of critical points, called Boltzmann and Bose, depending on the mean-field potential parameters. These critical points belong to different universality classes and have distinct sets of critical exponents. Pion and alpha matter are considered as examples of Boltzmann and Bose critical points, respectively. Generally, the phase diagram can have either one or both of these critical points.
