Title: | Controlling the ratchet effect for cold atoms | Authors: | Kenfack, A. Gong, J. Pattanayak, A.K. |
Issue Date: | 31-Jan-2008 | Citation: | Kenfack, A., Gong, J., Pattanayak, A.K. (2008-01-31). Controlling the ratchet effect for cold atoms. Physical Review Letters 100 (4) : -. ScholarBank@NUS Repository. https://doi.org/10.1103/PhysRevLett.100.044104 | Abstract: | Low-order quantum resonances manifested by directed currents have been realized with cold atoms. Here we show that by increasing the strength of an experimentally achievable delta-kicking ratchet potential, quantum resonances of a very high order may naturally emerge and can induce larger ratchet currents than low-order resonances, with the underlying classical limit being fully chaotic. The results offer a means of controlling quantum transport of cold atoms. © 2008 The American Physical Society. | Source Title: | Physical Review Letters | URI: | http://scholarbank.nus.edu.sg/handle/10635/96101 | ISSN: | 00319007 | DOI: | 10.1103/PhysRevLett.100.044104 |
