If frequent measurements ascertain whether a quantum system is still in its initial state,
transitions to other states are hindered and the quantum Zeno effect takes place. However …

Quantum transients are temporary features of matter waves before they reach a stationary
regime. Transients may arise after the preparation of an unstable initial state or due to a …

The quantum Zeno effect is recast in terms of an adiabatic theorem when the measurement
is described as the dynamical coupling to another quantum system that plays the role of …

We analyze and compare three different strategies, all aimed at controlling and eventually
halting decoherence. The first strategy hinges upon the quantum Zeno effect, the second …

A series of frequent measurements on a quantum system (Zeno-like measurements) is
shown to result in the “purification” of another quantum system in interaction with the former …

A quantum Zeno dynamics can be obtained by means of frequent measurements, frequent
unitary kicks or a strong continuous coupling and yields a partition of the total Hilbert space …

We investigate what happens if an Anderson localized system is coupled to a small bath,
with a discrete spectrum, when the coupling between system and bath is specially chosen …

e− tA/2ne− tB/ne− tA/2n) n} n≥ 1 are called the symmetric (or symmetrised) products (or
approximants) for Lie product formulæ (1) and (2). Extension of the Lie-type product formulæ …

A method of purification, purification through Zeno-like measurements [H. Nakazato, T.
Takazawa, and K. Yuasa, Phys. Rev. Lett. 90, 060401 (2003)], is discussed extensively and …

We carry out a decoherent-histories analysis of the arrival-time problem, taking advantage of
a recently demonstrated connection between time-ordered strings of projection operators …
