Spin current generation and relaxation in a quenched spin-orbit-coupled Bose-Einstein condensate
Chuan-Hsun Li, Chunlei Qu, Robert J. Niffenegger +9
Understanding the effects of spin-orbit coupling (SOC) and many-body interactions on spin transport is important in condensed matter physics and spintronics. This topic has been in…
Tunable Landau-Zener transitions in a spin-orbit coupled Bose-Einstein condensate
Abraham J. Olson, Su-Ju Wang, Robert J. Niffenegger +3
The Landau-Zener (LZ) transition is one of the most fundamental phenomena in quantum dynamics. It describes nonadiabatic transitions between quantum states near an avoided crossing…
Optimizing the efficiency of evaporative cooling in optical dipole traps
Abraham J. Olson, Robert J. Niffenegger, Yong P. Chen
We present a combined computational and experimental study to optimize the efficiency of evaporative cooling for atoms in optical dipole traps. By employing a kinetic model of evap…
Effects of magnetic dipole-dipole interactions in atomic Bose-Einstein condensates with tunable s-wave interactions
Abraham J. Olson, Daniel L. Whitenack, Yong P. Chen
The s-wave interaction is usually the dominant form of interactions in atomic Bose-Einstein condensates (BECs). Recently, Feshbach resonances have been employed to reduce the stren…
