Calculation of mode coupling for quadrupole excitations in a Bose-Einstein condenstate
Physical Review A Atomic Molecular and Optical Physics 65:3 B (2002) 033612/9
Abstract:
A simple model describing the nonlinear coupling of quasiparticle amplitudes of two modes is derived. The model, in particular, can be used to study squeezing effects that are directly related to the matrix element governing the coupling process. This paper demonstrates how to calculate this matrix element analytically and focuses on the quadrupole excitations.Double-well magnetic trap for Bose-Einstein condensates

Abstract:
A magnetic trapping scheme for neutral atoms for studying the behavior of Bose-Einstein condensates in double-well potentials was presented. The trapping scheme was based on a hybrid of Ioffe-Pritchard and time-averaged orbital potential traps. The double-well magnetic potential obtained using the scheme was found to have readily controllable barrier height and well separation. © Oxford University Press 2002.Direct observation of irrotational flow and evidence of superfluidity in a rotating Bose-Einstein condensate
