Echo-Ramsey Interferometry with Motional Quantum States
D. Hu, L. X. Niu, S. J. Jin +4
Ramsey interferometers (RIs) using internal electronic or nuclear states find wide applications in science and engineering. We develop a matter wave Ramsey interferometer for motio…
Observation of quantum dynamical oscillations of ultracold atoms in the F and D bands of an optical lattice
Zhongkai Wang, Baoguo Yang, Dong Hu +4
We report the observation of quantum dynamical oscillations of ultracold atomic gases in the F and D bands of a single-well optical lattice. We are able to control the Bragg reflec…
Long-time nonlinear dynamical evolution for P-band ultracold atoms in an optical lattice
Dong Hu, Linxiao Niu, Baoguo Yang +4
We report the long-time nonlinear dynamical evolution of ultracold atomic gases in the P-band of an optical lattice. A Bose-Einstein condensate (BEC) is fast and efficiently loaded…
Excitation of atoms in an optical lattice driven by polychromatic amplitude modulation
Linxiao Niu, Dong Hu, Shengjie Jin +3
We investigate the mutiphoton process between different Bloch states in an amplitude modulated optical lattice. In the experiment, we perform the modulation with more than one freq…
