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…

Fermion interactions and universal behavior in strongly interacting theories
The theory of the strong interaction, quantum chromodynamics (QCD), describes the generation of hadronic masses and the state of hadronic matter during the early stages of the evolution of the
Functional renormalization group approach for tensorial group field theory: a rank-6 model with closure constraint
• Mathematics

We develop the functional renormalization group formalism for a tensorial group field theory with closure constraint, in the case of a just renormalizable model over U ( 1 ) ⨂ 6 , with quartic

First-order phase transitions in spinor Bose gases and frustrated magnets

We show that phase transitions in spin-1 Bose gases and stacked triangular Heisenberg antiferromagnets—an example of frustrated magnets with competing interactions—are described by the same
Critical Behavior of a Trapped Interacting Bose Gas
• Physics
Science
• 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.

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.
