Abstract

We study theoretically a generation of vortices by phase imprinting in trapped Bose-Einstein condensates. Phase imprinting is achieved by passing a short off-resonance laser pulse through an appropriately designed absorption plate, and impinging it on a condensate. We answer the fundamental question how the circulation and the vortex are introduced into the system. We discuss the possibility of multiple vortex arrays creation. Using multiple absorption plates we show that genuine vortex arrays and vortex-antivortex configurations can be created in a controlled way. We discuss vortex dynamics and interactions in such configurations. Various methods of vortex detection based on interference combined with Bragg scattering technique are also analyzed.

Optical generation of vortices in trapped Bose-Einstein condensates

Ł. Dobrek, Mariusz Gajda, Maciej Lewenstein +3 more

We demonstrate numerically the efficient generation of vortices in Bose-Einstein condensates (BECs) by using a ``phase imprinting'' method. The method consists of passing a far-off-resonant laser pulse through an absorption plate with an azimuthally dependent absorption coefficient, imaging the laser beam onto a BEC, and thus creating the corresponding nondissipative Stark-shift potential and condensate phase shift. In our calculations we take into account experimental imperfections. We also propose an interference method to detect vortices by coherently pushing part of the condensate using optically induced Bragg scattering.

Engineering vortex rings and systems for controlled studies of vortex interactions in Bose-Einstein condensates

Janne Ruostekoski, Zachary Dutton

We study controlled methods of preparing vortex configurations in atomic Bose-Einstein condensates and their use in the studies of fundamental vortex scattering, reconnection processes, and superfluid sound emission. We explore techniques of imprinting vortex rings by means of coherently driving internal atomic transitions with electromagnetic fields which exhibit singular phase profiles. In particular, we show that a vortex ring can be prepared by two focused co-propagating Gaussian laser beams. More complex vortex systems may also be imprinted by directly superposing simpler field configurations or by programming their phase profiles on optical holograms. We analyze specific examples of two merging vortex rings in a trapped two-species $^{87}\mathrm{Rb}$ gas. We calculate the radiated sound energy in the reconnection process and show that the vortex relaxation and the redistribution of sound energy can be controlled by the imprinting process. As another creation technique, we study engineering pairs of two-dimensional point vortices in the condensates using a `light roadblock' in ultraslow light propagation. We show how this can be used to study vortex collisions in compressible superfluids and how these collisions result in energy dissipation via phonons and, sometimes, annihilation of vortex pairs.

Vortices in Bose-Einstein Condensates: Some Recent Developments

Kevrekidis, Panos, R. Carretero-González, D. J. Frantzeskakis +1 more

In this brief review we summarize a number of recent developments in the study of vortices in Bose-Einstein condensates, a topic of considerable theoretical and experimental interest in the past few years. We examine the generation of vortices by means of phase imprinting, as well as via dynamical instabilities. Their stability is subsequently examined in the presence of purely magnetic trapping, and in the combined presence of magnetic and optical trapping. We then study pairs of vortices and their interactions, illustrating a reduced description in terms of ordinary differential equations for the vortex centers. In the realm of two vortices we also consider the existence of stable dipole clusters for two-component condensates. Last but not least, we discuss mesoscopic patterns formed by vortices, the so-called vortex lattices and analyze some of their intriguing dynamical features. A number of interesting future directions are highlighted.

Inducing Vortices in a Bose-Einstein Condensate Using Holographically Produced Light Beams

Brachmann, Johannes, Waseem Bakr, Jonathon I. Gillen +2 more

In this paper we demonstrate a technique that can create non-equilibrium vortex configurations with almost arbitrary charge and geometry in a Bose-Einstein condensate. We coherently transfer orbital angular momentum from a holographically generated light beam to a 87Rb condensate using a two-photon stimulated Raman process. Using matter wave interferometry, we verify the phase pattern imprinted onto the atomic wave function for a single vortex and a vortex-antivortex pair. In addition to their phase winding, the vortices created with this technique have an associated hyperfine spin texture.
