On the Convergence of the Linear Delta Expansion for the Shift in T_c for Bose-Einstein Condensation

Eric Braaten, Eugeniu Radescu

The leading correction from interactions to the transition temperature T_c for Bose-Einstein condensation can be obtained from a nonperturbative calculation in the critical O(N) sc…
