# Non Perturbative Renormalization Group and Bose-Einstein Condensation

@article{Blaizot2007NonPR, title={Non Perturbative Renormalization Group and Bose-Einstein Condensation}, author={J. P. Blaizot}, journal={arXiv: Statistical Mechanics}, year={2007} }

These lectures are centered around a specific problem, the effect of weak repulsive interactions on the transition temperature $T_c$ of a Bose gas. This problem provides indeed a beautiful illustration of many of the techniques which have been discussed at this school on effective theories and renormalization group. Effective theories are used first in order to obtain a simple hamiltonian describing the atomic interactions: because the typical atomic interaction potentials are short range, and…

Critical Behavior of a Trapped Interacting Bose Gas

- PhysicsScience
- 2007

The phase transition of Bose-Einstein condensation was studied in the critical regime, where fluctuations extend far beyond the length scale of thermal de Broglie waves, and matter-wave interference was used to measure the correlation length as a function of temperature.

Renormalization group flow equations with full momentum dependence

- PhysicsPhilosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences
- 2011

A particular truncation of the hierarchy of flow equations that allows for the determination of the full momentum of the n-point functions is discussed, to critical O(N) models, to Bose–Einstein condensation and to finite-temperature field theory.
