Dynamical mean-field driven spinor condensate physics beyond the single-mode approximation
J. Jie, S. Zhong, Q. Zhang +7
Na spin-1 Bose-Einstein condensates are used to experimentally demonstrate that mean-field physics beyond the single-mode approximation can be relevant during the non-equili…
Tailored generation of quantum states in an entangled spinor interferometer to overcome detection noise
Q. Guan, G. W. Biedermann, A. Schwettmann +1
We theoretically investigate how entangled atomic states generated via spin-changing collisions in a spinor Bose-Einstein condensate can be designed and controllably prepared for a…
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…
FPGA-Controlled Versatile Microwave Source for Cold Atom Experiments
Isaiah Morgenstern, Shan Zhong, Qimin Zhang +4
We present a microwave source that is controlled by a commercially available field programmable gate array (FPGA). Using an FPGA allows for precise control of the time dependent mi…
Quantum Interferometry with Microwave-dressed F=1 Spinor Bose-Einstein Condensates: Role of Initial States and Long Time Evolution
Qimin Zhang, Arne Schwettmann
We numerically investigate atomic interferometry based on spin-exchange collisions in spinor Bose-Einstein condensates in the regime of long evolution times , where…
A spinor Bose-Einstein condensate phase-sensitive amplifier for SU(1,1) interferometry
J. P. Wrubel, A. Schwettmann, D. P. Fahey +6
The SU(1,1) interferometer was originally conceived as a Mach-Zehnder interferometer with the beam-splitters replaced by parametric amplifiers. The parametric amplifiers produce st…
