Issue Date: | Feb-2006 | Citation: | Kwek, L.C., Tong, D.M., Chen, J.L., Du, J.F., Choo, K.W., Ravishankar, R., Kaszlikowski, D., Oh, C.H. (2006-02). Geometric phase for mixed states. Laser Physics 16 (2) : 398-401. ScholarBank@NUS Repository. | Abstract: | We present a kinematic approach for obtaining the geometric phase of a mixed state under nonunitary evolution. This phase is gauge-invariant and measurable and leads to well-known results for unitary evolution. © Nauka/Interperiodica 2006. | Source Title: | Laser Physics | URI: | http://scholarbank.nus.edu.sg/handle/10635/114336 | ISSN: | 1054660X |
