Title: Finite Temperature Scaling Theory for the Collapse of Bose-Einstein Condensate
Speaker: Shyamal Biswas (IACS, Kolkata)
Abstract: We show how to apply the scaling theory in an inhomogeneous system like harmonically trapped Bose condensate at finite temperatures. We calculate the temperature dependence of the critical number of particles by a scaling theory within the Hartree-Fock approximation and find that there is a dramatic increase in the critical number of particles as the condensation point is approached. Our results support the experimental result which was obtained well below the condensation temperature.
