|Title:||Chaos and correspondence in classical and quantum Hamiltonian ratchets: A Heisenberg approach||Authors:||Pelc, J.
|Issue Date:||16-Jun-2009||Citation:||Pelc, J., Gong, J., Brumer, P. (2009-06-16). Chaos and correspondence in classical and quantum Hamiltonian ratchets: A Heisenberg approach. Physical Review E - Statistical, Nonlinear, and Soft Matter Physics 79 (6) : -. ScholarBank@NUS Repository. https://doi.org/10.1103/PhysRevE.79.066207||Abstract:||Previous work motivates this study as to how asymmetry-driven quantum ratchet effects can persist despite a corresponding fully chaotic classical phase space. A simple perspective of ratchet dynamics, based on the Heisenberg picture, is introduced. We show that ratchet effects are in principle of common origin in classical and quantum mechanics, although full chaos suppresses these effects in the former but not necessarily the latter. The relationship between ratchet effects and coherent dynamical control is noted. © 2009 The American Physical Society.||Source Title:||Physical Review E - Statistical, Nonlinear, and Soft Matter Physics||URI:||http://scholarbank.nus.edu.sg/handle/10635/95946||ISSN:||15393755||DOI:||10.1103/PhysRevE.79.066207|
