Symmetry Breaking in Bose-Einstein Condensates

A gaseous Bose-Einstein condensate (BEC) offers an ideal testing ground for studying symmetry breaking, because a trapped BEC system is in a mesoscopic regime, and situations exist under which symmetry breaking may or may not occur. Investigating this problem can explain why mean-field theories have been so successful in elucidating gaseous BEC systems and when manybody effects play a significa...

Stability and Collapse Dynamics of Dipolar Bose-Einstein Condensates in One-Dimensional Optical Lattices

The subject of this thesis is the investigation of the stability and the collapse dynamics of a dipolar 52Cr Bose-Einstein condensate (BEC) in a one-dimensional (1D) optical lattice potential. In this work, it is experimentally shown that the stability of the dipolar BEC is strongly modified when increasing the modulation depth of the sinusoidal potential landscape: a cross-over from dipolar de...

Effective field theory for spinor dipolar Bose Einstein condensates

We show that the effective theory of long wavelength low energy behavior of a dipolar BoseEinstein condensate(BEC) with large dipole moments (treated as a classical spin) can be modeled using an extended Non-linear sigma model (NLSM) like energy functional with an additional non-local term that represents long ranged anisotropic dipole-dipole interaction. Minimizing this effective energy functi...

Dimension reduction for dipolar Bose-Einstein condensates in the strong interaction regime

We study dimension reduction for the three-dimensional GrossPitaevskii equation with a long-range and anisotropic dipole-dipole interaction modeling dipolar Bose-Einstein condensation in a strong interaction regime. The cases of disk shaped condensates (confinement from dimension three to dimension two) and cigar shaped condensates (confinement to dimension one) are analyzed. In both cases, the...

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...
