Phys. Rev. A 64, 042111 (2001) [4 pages]Quantum Zeno-like effect due to competing decoherence mechanismsReceived 12 February 2001; published 18 September 2001 We propose a self-consistent quantum mechanical approach to study the dynamics of a two-level system subject to random time evolution. This randomness gives rise to competing effects between dissipative and nondissipative decoherence with a consequent slowdown of the atomic decay rate. © 2001 The American Physical Society URL:
