چکیده

We investigate the quench dynamics of quasi-one and two dimensional dipolar Bose-Einstein condensates (dBEC) $^{164}$Dy atoms under influence a fast rotating magnetic field. The field thus controls both magnitude sign potential. account for quantum fluctuations, critical to formation exotic droplet supersolid phases in extended Gross-Pitaevskii formalism, which includes so-called Lee-Huang-Yang (LHY) correction. An analytical variational ansatz allows us obtain phase diagrams superfluid phases. crossover from single arrays is probed with particle number interaction. strength tuned by subsequent effects on boundaries. Following interaction quenches across aforementioned phases, we monitor dynamical clusters or lattices. include losses due three-body recombination over regime, where rate coefficient scales fourth power scattering length ($a_s$) dipole ($a_{dd}$). For fixed values dimensionless parameter, $\epsilon_{dd} = a_{dd}/a_s$, tuning anisotropy leads an enhancement lifetimes.

Strongly dipolar Bose-Einstein condensate of dysprosium.

We report the Bose-Einstein condensation (BEC) of the most magnetic element, dysprosium. The Dy BEC is the first for an open f-shell lanthanide (rare-earth) element and is produced via forced evaporation in a crossed optical dipole trap loaded by an unusual, blue-detuned and spin-polarized narrowline magneto-optical trap. Nearly pure condensates of 1.5 × 10(4) (164)Dy atoms form below T = 30 nK...

Dynamical instability of a rotating dipolar Bose-Einstein condensate.

We analyze the hydrodynamic solutions for a dilute Bose-Einstein condensate with long-range dipolar interactions in a rotating, elliptical harmonic trap. The static solutions and their regimes of dynamical instability vary nontrivially with the strength of the dipolar interactions. We comprehensively map out this behavior, and, in particular, examine the experimental routes toward unstable dyna...

Exact hydrodynamics of a trapped dipolar Bose-Einstein condensate.

We present exact results in the Thomas-Fermi regime for the statics and dynamics of a harmonically trapped Bose-Einstein condensate that has dipole-dipole interactions in addition to the usual s-wave contact interactions. Remarkably, despite the nonlocal and anisotropic nature of the dipolar interactions, the density profile in a general time-dependent harmonic trap is an inverted parabola. The...

How Does a Dipolar Bose-Einstein Condensate Collapse?

We emphasize that the macroscopic collapse of a dipolar Bose-Einstein condensate in a pancake-shaped trap occurs through local density fluctuations, rather than through a global collapse to the trap center. This hypothesis is supported by a recent experiment in a chromium condensate. Based on an invited talk in Seminar 6, Physics of Cold Trapped Atoms, at the 17th International Laser Physics Wo...

Spin Hall effect in a spinor dipolar Bose-Einstein condensate

We theoretically show that the spin Hall effect arises in a Bose-Einstein condensate (BEC) of neutral atoms interacting via the magnetic dipole-dipole interactions (MDDIs). Since the MDDI couples the total spin angular momentum and the relative orbital angular momentum of two colliding atoms, it works as a spin-orbit coupling. Thus, when we prepare a BEC in a magnetic sublevel m = 0, thermally ...
