Soliton Atom Laser with Quantum State Transfer Property

Xiong-Jun Liu, Hui Jing, Mo‐Lin Ge

We propose a scheme to obtain soliton atom laser with nonclassical atoms based on quantum state transfer process from light to matter waves in nonlinear case, which may find novel applications in, e.g., an atom interferometer. The dynamics of the atomic gray solitons and the accompanied frequency chirp effect are discussed.

Soliton Atom Laser with Quantum State Transfer Property

Xiong-Jun Liu, Jing Hui, Mo‐Lin Ge

We study the nonlinear effects in the quantum states transfer technique from photons to matter waves in the three-level case, which may provide the formation of a soliton atom laser with nonclassical atoms. The validity of quantum transfer mechanism is confirmed in the presence of the intrinsic nonlinear atomic interactions. The accompanied frequency chirp effect is shown to have no influence on the grey solitons formed by the output atom laser and the possible quantum depletion effect is also briefly discussed.We study the nonlinear effects in the quantum states transfer technique from photons to matter waves in the three-level case, which may provide the formation of a soliton atom laser with nonclassical atoms.

Soliton Atom Laser via Quantum State Transfer Process

Xiong-Jun Liu, Hui Jing, Mo‐Lin Ge

We theoretically examine quantum state transfer from light to an interacting atomic beam, focusing on generation of soliton atom laser in the output state. This problem is an extension of the Fleischhauer-Gong scheme [M. Fleischhauer and S. Gong, Phys. Rev. Lett. 88, 070404 (2002)] by including the role of nonlinear atomic interactions. The transfer process of quantum state is, however, from photons to created atomic gray-soliton whose dynamics is free of the accompanied frequency chirp effect, indicating a novel scheme for soliton atom laser with nonclassical state.We theoretically examine quantum state transfer from light to an interacting atomic beam, focusing on generation of soliton atom laser in the output state.
