Zeno Hall Effect

Quantum Anti–Zeno Effect

The interplay between quantum dynamics and quantum measuments continues to attract attention of physicists since the birth of quantum physics [1]. One of the classic examples of such an interplay is the, so called, quantum Zeno effect [2]. It consists in modifying the quantum evolution by the repeated measurments. The essence of the quantum Zeno effect is that repeated interrogation if the syst...

A relativistic Zeno effect

A Zenonian supertask involving an infinite number of identical colliding balls is generalized to include balls with different masses. Under the restriction that the total mass of all the balls is finite, classical mechanics leads to velocities that have no upper limit. Relativistic mechanics results in velocities bounded by that of light, but energy and momentum are not conserved, implying inde...

Quantum Zeno and Anti-Zeno Effect without Rotating Wave Approximation

The effect of the anti-rotating terms on the short-time evolution and the quantum Zeno (QZE) and anti-Zeno (AQZE) effects is studied for a two-level system coupled to a bosonic environment. A unitary transformation and perturbation theory are used to obtain the electron self-energy, energy shift and the enhanced QZE or the AQZE, simultaneously. The calculated Zeno time depends on the atomic tra...

Understanding the quantum Zeno effect

The quantum Zeno effect consists in the hindrance of the evolution of a quantum system that is very frequently monitored and found to be in its initial state at every single measurement. On the basis of the correct formula for the survival probability, i.e. the probability of finding the system in its initial state at every single measurement, we critically analyze a recent proposal and experim...
