Stability in Bose-Einstein Condensates
نویسنده
چکیده
In this work the validity of an analytic approximation expression [1] for the critical number of atoms that a Bose-Einstein Condensate can hold before collapsing when the interaction between them is attractive is checked. In order to do this the system is treated in a more precise way by numerically solving the Gross-Pitaevskii equation. One finds that the variational approach underestimates the number of atoms that can fit in a Bose-Einstein Condensate before it collapses.

Stability 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 کاملStudy on the Stabilization of Attractive Bose-einstein Condensates Using Projection Operator Method
We study the stability of Bose-Einstein condensates (BECs) with attractive twoand three-body interactions by analyzing the nonlinear, cubic quintic Gross-Pitaevskii equation (CQGPE). By employing a projection operator method we discuss the stabilization of an attractive BEC by varying the strength of the trapping potential. Our analysis suggests that the reduction in strength of the external tr...
متن کاملStability of dark solitons in three dimensional dipolar Bose-Einstein condensates.
The dynamical stability of dark solitons in dipolar Bose-Einstein condensates is studied. For standard short-range interacting condensates, dark solitons are unstable against transverse excitations in two and three dimensions. On the contrary, due to its nonlocal character, the dipolar interaction allows for stable 3D stationary dark solitons, opening a qualitatively novel scenario in nonlinear...
متن کاملVortices in atomic-molecular Bose–Einstein condensates
The structure and stability of vortices in hybrid atomic-molecular Bose–Einstein condensates is analysed in the framework of a two-component Gross–Pitaevskii-type model that describes the stimulated Raman-induced photoassociation process. New types of topological vortex states are predicted to exist in the coherently coupled two-component condensates even without a trap, and their nontrivial dy...
متن کاملLocalized breathing oscillations of Bose-Einstein condensates in periodic traps
We demonstrate the existence of localized oscillatory breathers for quasi-one-dimensional Bose-Einstein condensates confined in periodic potentials. The breathing behavior corresponds to position oscillations of individual condensates about the minima of the potential lattice. We deduce the structural stability of the localized oscillations from the construction. The stability is confirmed nume...
متن کاملVariational methods with coupled Gaussian functions for Bose-Einstein condensates with long-range interactions. I. General concept
The variational method of coupled Gaussian functions is applied to Bose-Einstein condensates with long-range interactions. The time dependence of the condensate is described by dynamical equations for the variational parameters. We present the method and analytically derive the dynamical equations from the time-dependent Gross-Pitaevskii equation. The stability of the solutions is investigated ...
