Momentum Distribution for an Inhomogeneous Bose Fluid atT= 0 with Both Confinement and Particle Interactions Modelled as Harmonic
Norman Henry March, M. P. Tosi
Because of experimental interest in the effects of particle interactions in Bose condensates, such as a dilute atomic vapour of 87Rb, we have worked out the momentum distribution in an N-Boson many-body assembly at T = 0, for which both confinement and interbosonic interactions are modelled as purely harmonic. The half-width of the Gaussian momentum distribution is displayed as a function of N and of the strength and sign of the harmonic interactions. The bosonic kinetic energy is finally treated.
