Nonlinear multi-state tunneling dynamics in a spinor Bose-Einstein condensate
Z. N. Hardesty-Shaw, Q. Guan, J. O. Austin-Harris +3
We present an experimental realization of dynamic self-trapping and non-exponential tunneling in a multi-state system consisting of ultracold sodium spinor gases confined in moving…
Temperature-Dependent Contact of Weakly Interacting Single-Component Fermi Gases and Loss Rate of Degenerate Polar Molecules
Xin-Yuan Gao, D. Blume, Yangqian Yan
Motivated by the experimental realization of single-component degenerate Fermi gases of polar ground state KRb molecules with intrinsic two-body losses [L. De Marco, G. Valtolina,…
Mean-field spin-oscillation dynamics beyond the single-mode approximation for a harmonically trapped spin-1 Bose-Einstein condensate
Jianwen Jie, Q. Guan, S. Zhong +2
Compared to single-component Bose-Einstein condensates, spinor Bose-Einstein condensates display much richer dynamics. In addition to density oscillations, spinor Bose-Einstein con…
Rabi oscillations and Ramsey-type pulses in ultracold bosons: Role of interactions
Q. Guan, T. M. Bersano, S. Mossman +2
Double-well systems loaded with one, two, or many quantum particles give rise to intriguing dynamics, ranging from Josephson oscillation to self-trapping. This work presents theore…
Spinor Bose-Einstein Condensate Interferometer within the Undepleted Pump Approximation: Role of the Initial State
Jianwen Jie, Q. Guan, D. Blume
Most interferometers operate with photons or dilute, non-condensed cold atom clouds in which collisions are strongly suppressed. Spinor Bose-Einstein condensates (BECs) provide an…
Electric-field induced helium-helium resonances
Qingze Guan, Doerte Blume
The tunability of the helium-helium interaction through an external electric field is investigated. For a static external field, electric-field induced resonances and associated el…
