|Title:||Controlling the ratchet effect for cold atoms||Authors:||Kenfack, A.
|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|
