The experimental realisation of Bose–Einstein condensates of dilute atomic vapours has
generated immense interest and activity in this field. Here, we present a review of recent …

Stimulated small-angle light scattering was used to measure the structure factor of a Bose-
Einstein condensate in the phonon regime. The excitation strength for phonons was found to …

We present a detailed theoretical analysis of Bragg spectroscopy from a Bose-Einstein
condensate at T= 0 K. We demonstrate that within the linear-response regime, both a …

We study the quantum field theory of light-matter interactions for quantum degenerate atomic
gases at low light intensity. We argue that the contact interactions between atoms emerging …

We calculate the spectrum of the scattered light from quantum degenerate atomic gases
obeying Bose-Einstein statistics. The atoms are assumed to occupy two ground states …

Impressive pictures of moving Bose-Einstein condensates have been taken using phase-
contrast imaging [MR Andrews et al., Science 273, 84 (1996)]. We calculate the quantum …

We consider a trapped quasi-two-dimensional dipolar Bose-Einstein condensate with a
polarization tilted into the plane of motion. We show that by tilting the polarization axis, the …

In this article, we focus on describing the inelastic particle scattering by quantum scatterers
in a rotating harmonic trap with the presence of delta potential. We have obtained an …

The Bogoliubov equations of the quasiparticle excitations in a weakly interacting trapped
Bose condensate are solved in the WKB approximation in an isotropic harmonic trap …

The WKB approximation for the Bogoliubov equations of the quasiparticle excitations in
Bose gases with a condensate is worked out in the case of spherically symmetric trap …
