Quantum Zeno and anti-Zeno Effects: An Exact Model
T. C. Dorlas, R. F. O'Connell
Abstract
Recent studies suggest that both the quantum Zeno (increase of the natural lifetime of an unstable quantum state by repeated measurements) and anti-Zeno (decrease of the natural lifetime) effects can be made manifest in the same system by simply changing the dissipative decay rate associated with the environment. We present an exact calculation confirming this expectation.
