Coherent States of the Creation Operator from Fully Developed Bose-Einstein Condensates
نویسنده
چکیده
A fully developed Bose-Einstein condensate, containing macroscopically large number of bosons can under certain conditions be considered as a generalized vacuum state. Applying the annihilation operator to the condensate hole states can be defined. Infinite ladders of such hole states can be considered as generalized coherent states of the creation operator. Dedicated to the memory of Professor V. N. Gribov.

Arbitrary 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...
متن کاملSolitons for nearly integrable bright spinor Bose-Einstein condensate
Using the explicit forms of eigenstates for linearized operator related to a matrix version of Nonlinear Schrödinger equation, soliton perturbation theory is developed for the $F=1$ bright spinor Bose-Einstein condensates. A small disturbance of the integrability condition can be considered as a small correction to the integrable equation. By choosing appropriate perturbation, the soli...
متن کاملStability of atomic–molecular coherent states of hybrid Bose–Einstein condensates
We study the stability of coherent atomic–molecular states of hybrid Bose–Einstein condensates in the framework of the parametrically coupled Gross–Pitaevskii equations with a weak ‘short-correlated’ noise, also taking into account the self-interaction effects described by the cubic nonlinearity. We show that the stationary states of the hybrid atomic–molecular condensates are much more robust ...
متن کاملSagnac Effect in superpositions of vortex states in Bose-Einstein Condensates
Creation and manipulation of macroscopic superposition as well as entangled Bose-Einstein condensates (BEC) with all-optical means has become feasible over the years and corresponds to a mature technology with important applications to quantum information. In an entirely different area of optical manipulations, tremendous progress has been made in creating, manipulating and measuring orbital an...
متن کاملProposal for the creation and optical detection of spin cat states in Bose-Einstein condensates.
We propose a method to create "spin cat states," i.e., macroscopic superpositions of coherent spin states, in Bose-Einstein condensates using the Kerr nonlinearity due to atomic collisions. Based on a detailed study of atom loss, we conclude that cat sizes of hundreds of atoms should be realistic. The existence of the spin cat states can be demonstrated by optical readout. Our analysis also inc...
