Informal Pizza SeminarInteraction Corrections to Atomic Bose-Einstein Condensation TemperatureGuy MooreMcGillThe relation between number density and condensation temperature, for a non-interacting gas of Bose particles, has been known since the 1920's. The first corrections in scattering length, in the limit of small a/λ T (`a' the s-channel scattering length, `λ T' the thermal deBroglie wavelength), was found by us in 2001. (This is the regime relevant for atomic Bose-Einstein condensation.) In this talk I will show how effective field theory techniques and lattice methods, developed for relativistic field theory, could be applied to this very different problem.
