Symmetry Breaking and a Dynamical Property of a Dipolar Bose–Einstein Condensate in a Triple-Well Potential

Abstract

We investigate the properties of a three-dimensional (3D) dipolar Bose–Einstein condensate (BEC) in a triple-well potential. Symmetry breaking and self-trapping (SBST) phenomena are demonstrated for 52Cr atoms in the 3D triple-well potential using numerical solutions of the Gross–Pitaevskii (GP) equation. The results show that the ground-state density distributions are affected markedly by the long-range nature and anisotropy of the dipolar interaction and the isotropic s-wave contact interaction. In addition, the dynamical picture of the SBST induced by a gradual transformation of the single-well potential into a triple-well one is also illustrated. SBST phenomena are also presented by adjusting the height of the middle potential well when the dipole orientation is aligned in the dipole axis.

Symmetry breaking and tunneling dynamics of a dipolar Bose–Einstein condensate in a double-well potential

Yuan Sheng Wang, Ping Long, Bo Zhang +1 more

We investigate the properties of a three-dimensional (3D) dipolar Bose–Einstein condensate (BEC) in a double-well potential (DWP). Symmetry breaking and tunneling dynamics phenomena are demonstrated for 164Dy atoms in the 3D DWP using an effective two-mode model. The results show that the symmetry properties of the dynamics are affected markedly by the long-range nature and anisotropy of the dipolar interaction and the isotropic contact interaction.

Tunneling Dynamics of a Dipolar Bose–Einstein Condensate in a Double-Well Potential

Yuan-Sheng Wang, Qiuping Yang, Jing Wang

We investigate the tunneling dynamics of a three-dimensional (3D) cigar-shaped dipolar Bose–Einstein condensate (BEC) of 52Cr atoms in an axially-symmetric double-well potential (DWP). By introducing asymmetric basis functions, we improve the effective two-mode model. The results obtained by numerical solutions of the 3D Gross–Pitaevskii (GP) equation and the 3D two-mode approximation methods are basically in accordance with each other at different polarization angles.

Dipolar Bose-Einstein condensate in a ring or in a shell

Sadhan K. Adhikari

We study properties of a trapped dipolar Bose-Einstein condensate (BEC) in a circular ring or a spherical shell using the mean-field Gross-Pitaevskii equation. In the case of the ring-shaped trap we consider different orientations of the ring with respect to the polarization direction of the dipoles. In the presence of long-range anisotropic dipolar and short-range contact interactions, the anisotropic density distribution of the dipolar BEC in both traps is discussed in detail. The stability condition of the dipolar BEC in both traps is illustrated in a phase plot of dipolar and contact interactions. We also study and discuss the properties of a vortex dipolar BEC in these traps.

Nonlinear dynamics of Rydberg-dressed Bose-Einstein condensates in a triple-well potential

Gary McCormack, Rejish Nath, Weibin Li

We study nonlinear dynamics of Rydberg-dressed Bose-Einstein condensates (BECs) trapped in a triple-well potential in the semiclassical limit. The Rydberg-dressed BECs experience a long-range soft-core interaction, giving rise to strong nearest- and next-nearest-neighbor interactions in the triple-well system. Using mean-field Gross-Pitaevskii (GP) equations, we show that lower branches of the eigenspectra exhibit loops and level crossings when the soft-core interaction is strong. The direct level crossings eliminate the possibility of adiabatic Landau-Zener transitions when tilting of the triple-well potential. We demonstrate that the long-range interaction allows for self-trapping in one, two, or three wells, in a far more controllable manor than BECs with short-range or dipolar interactions. Exact quantum simulations of the three-well Bose-Hubbard model indicate that self-trapping and nonadiabatic transition can be observed with less than a dozen bosons. Our study is relevant to current research into collective excitation and nonlinear dynamics of Rydberg-dressed atoms.

Mean-field description of dipolar bosons in triple-well potentials

D Peter, Krzysztof Pawłowski, Tilman Pfau +1 more

We investigate the ground-state properties of a polarized dipolar Bose–Einstein condensate trapped in a triple-well potential. By solving the dipolar Gross–Pitaevskii equation numerically for different geometries we identify states which reveal the non-local character of the interaction. Depending on the strength of the contact and dipolar interaction we depict the stable and unstable regions in parameter space.

Formation of vortices in a three-dimensional dipolar Bose-Einstein condensate

Yuan Sheng Wang, Shen Tong Ji, Yue E. Luo +1 more

We investigate the vortex formation properties of a three-dimensional (3D) dipolar Bose-Einstein condensate (BEC) of 52 Cr atoms in an optical lattice potential through numerical simulations of the time-dependent Gross-Pitaevskii equation with a dissipation term. The mechanisms that influence the dipole-dipole interaction and the repulsive contact interaction between atoms during vortex formation are analyzed. We find that the stability of the vortices weakens with increasing attractive dipolar strength and that the repulsive contact interaction between atoms can increase the number of vortices.
