Quantum Zeno and Anti-Zeno Effects in the Dynamics of Non-Degenerate Hyper-Raman Processes Coupled to Two Linear Waveguides
-Raman processes is studied in terms of quantum Zeno and anti-Zeno effects as quantum Zeno (anti-Zeno) effect. This study considers the two probe waveguides that quantum Zeno (an...

A product formula related to quantum zeno dynamics
We prove a product formula which involves the unitary group generated by a semibounded self-adjoint operator and an orthogonal projection P on a separable Hilbert space H, with the convergence in L-loc(2)(R; H). It gives a partial answer to the quest...

On Relations Between Stable and Zeno Dynamics in a Leaky Graph Decay Model
We use a caricature model of a system consisting of a quantum wire and a finite number of quantum dots, to discuss relation between the Zeno dynamics and the stable one which governs time evolution of the dot state...

Linear and nonlinear quantum Zeno and anti-Zeno effects in a nonlinear optical coupler
Quantum Zeno and anti-Zeno effects are studied in a symmetric nonlinear optical generation. However, to study quantum Zeno and anti-Zeno effects one of them, and this dependence is considered as <...

Quantum Zeno effect in cascaded parametric down-conversion with losses
Quantum Zeno effect is considered in parametric down-conversion with losses. In the optical region and for room temperatures quantum noise influences are not substantial for observation. Quantum losses in signal be...

Unstable System Dynamics: Do We Understand It Fully?
We review some recent results in the theory of decaying quantum systems related to the Zeno and anti-Zeno effects. We also give an example showing that contrary to common belief the decay law can be a rather irregular funct...

Sufficient conditions for the anti-zero effect
The ideal anti-Zeno effect means that a perpetual observation leads to an immediate disappearance of the unstable system. We present a straightforward way to derive sufficient conditions under which such a situation occurs expressed in terms...

Quantum Zeno effect in Raman scattering
Zeno and inverse Zeno effects are demonstrated in Raman (Brillouin) scattering of strong coherent as well as quantum pump beams including phase mismatches. Raman coupler is used to control optical beams involved by means of...
