Quantized circulation in dilute Bose–Einstein condensates
We compute using a microscopic mean-field theory the structure and the quasiparticle excitation spectrum of a dilute, trapped Bose–Einstein condensate penetrated by an axisymmetric vortex line. The Gross–Pitaevskii equation for the condensate and the coupled Hartree–Fock–Bogoliubov–Popov equations describing the elementary excitations are solved self-consistently using finite-difference methods...

متن کاملQuantized Vortex States and Dynamics in Bose-einstein Condensates
In this thesis, we analytically and numerically study quantized vortex states aswell as their dynamics in rotating Bose-Einstein condensate at extremely low tem-perature.We present an efficient method–gradient flow with discrete normalization tofind the stationary solutions of the Gross-Pitaevskii equation and coupled Gross-Pitaevskii equations. We give a mathematical justif...
متن کاملManipulating Bose-Einstein condensates with laser light
A dilute gas Bose-Einstein condensate was probed and manipulated by off-resonant laser beams. Spontaneous and stimulated off-resonant light scatterings were studied experimentally. Stimulated, two-photon Bragg scattering was used for spectroscopic measurement of the mean-field energy and of the intrinsic momentum uncertainty of the condensate. The high momentum and energy resolution of this met...
متن کاملArbitrary coherent superpositions of quantized vortices in Bose-Einstein condensates via orbital angular momentum of light
We recently proposed a scheme for the creation of coherent superpositions of vortex states in Bose-Einstein condensates BECs using orbital angular momentum OAM states of light Phys. Rev. Lett. 95, 173601 2005 . Here we discuss further technical details of the proposal, provide an alternative, time-reversalsymmetric scheme for transfer of a superposition of OAM states of light to the BEC via a p...
