Phys. Rev. A 73, 064101 (2006) [3 pages]Conserved current in Markovian open-quantum systemsReceived 30 March 2006; published 19 June 2006 We reexamine the Markovian approximation of local current in open quantum systems, discussed recently by Gebauer and Car. Our derivation is more transparent; the proof of the current conservation becomes explicit and easy. © 2006 The American Physical Society URL:
