PHYSICAL MATHEMATICS SEMINAR
TOPIC: TOWARD A GENERAL THEORY
OF BOSE-EINSTEIN CONDENSATION
SPEAKER: DR. DIONISIOS MARGETIS

ABSTRACT:
An exciting recent advance in physics is the first experimental
observation of Bose-Einstein condensation in dilute atomic gases. In
these experiments, a trap is used to keep the atoms together for
evaporative cooling below the phase transition. It is the purpose of this
talk to describe a theory that treats systematically the effect of such an
external potential on Bose-Einstein condensation. An essential element of
this theory is the consideration of atoms excited in pairs from the
macroscopic state. The talk also provides an explicit example of
non-perturbative effects in quantum field theory.
