Talk

Abstract: In this talk I will describe our recent experiments studying spin-dependent quantum transport/collision as well as chemical reactions in a Bose-Einstein condensate (BEC) of ultracold (87Rb) atoms subject to optically-generated “synthetic” spin-orbit coupling (SOC). By performing a “quantum quench” (suddenly reducing the optical Raman coupling that generates the synthetic SOC and...

Talk

We trace the perturbative refinement of the two-boson interaction -- which augments an initial, unitary description by a finite effective range -- up to the six-boson system. Hereby, we expose a significant dependence of the predicted ground-state energies of tetra-, penta-, and hexameres on details of the interaction which is resolved at distances much smaller than the effective range. We...

Talk

Elastic scattering of three bosons at low energy is a fundamental problem in the many-body description of ultracold Bose gases, entering via the three-body scattering hypervolume $D$. We study this quantity for identical bosons that interact via a pairwise finite-range potential. Our calculations cover the regime from strongly repulsive potentials towards attractive potentials supporting...

Talk

On the three-body kinematics, the author proposed a $general$ $particle$ $\it{transfer}$ (GPT) potential which appears, not only at the three-body break-up threshold, but also at the quasi two-body threshold.The new potential represents a Yukawa-type potential for shorter range,but a $1/r^n$-type potential for longer range. The longer range part of the GPT potential for $n=1$ indicates an...
