Bragg spectroscopy of discrete axial quasiparticle modes in a cigar-shaped degenerate Bose gas
Tarun Kanti Ghosh
We propose an experiment in which long wavelength discrete axial quasiparticle modes can be imprinted in a 3D cigar-shaped Bose-Einstein condensate by using two-photon Bragg scatte…
Quantized Hydrodynamic Theory of One-Dimensional Hard Core Bosons
Tarun Kanti Ghosh
We present a quantized hydrodynamic theory and its applications of one-dimensional hard-core bosons in a harmonic trap. Quantizing the Hamiltonian of a trapped hard-core bosons and…
Quasi-one dimensional degenerate Bose gas
Tarun Kanti Ghosh
Motivated by the MIT experiment [Gorlitz {\em et al.}, Phys. Rev. Lett. {\bf 87}, 130402 (2001)], we analytically study the effect of density and phase fluctuations on various obse…
Vortex formation in a slowly rotating Bose-Einstein condensate confined in a harmonic-plus-gaussian laser trap
Tarun Kanti Ghosh
Motivated by the recent experiment at ENS [ V. Bretin, S. Stock, Y. Seurin and, J. Dalibard, Phys. Rev. Lett. {\bf 92}, 050403 (2004)], we study a rotating (non-)interacting atomic…
Vortex formation in a fast rotating Bose-Einstein condensate
Tarun Kanti Ghosh
We study rotational motion of an interacting atomic Bose-Einstein condensate confined in a quadratic-plus-quartic potential. We calculate the lowest energy surface mode frequency a…
Collective excitation frequencies and vortices of a Bose-Einstein condensed state with gravity-like interatomic attraction
Tarun Kanti Ghosh
We study the collective excitations of a neutral atomic Bose-Einstein condensate with gravity-like interatomic attraction induced by electromagnetic wave. Using the time-dep…
