Slow relaxation, confinement, and solitons
L. S. Schulman, E. Mihokova, A. Scardicchio +4
Millisecond crystal relaxation has been used to explain anomalous decay in doped alkali halides. We attribute this slowness to Fermi-Pasta-Ulam solitons. Our model exhibits confine…
Quantum Zeno phenomena: pulsed versus continuous measurement
P. Facchi, S. Pascazio
The time evolution of an unstable quantum mechanical system coupled with an external measuring agent is investigated. According to the features of the interaction Hamiltonian, a qu…
Mesoscopic interference
P. Facchi, A. Mariano, S. Pascazio
We analyze a double-slit experiment when the interfering particle is "mesoscopic" and one endeavors to obtain Welcher Weg information by shining light on it. We derive a compact ex…
Quantum Zeno effects with "pulsed" and "continuous" measurements
P. Facchi, S. Pascazio
The dynamics of a quantum system undergoing measurements is investigated. Depending on the features of the interaction Hamiltonian, the decay can be slowed (quantum Zeno effect) or…
Zeno dynamics yields ordinary constraints
P. Facchi, S. Pascazio, A. Scardicchio +1
The dynamics of a quantum system undergoing frequent measurements (quantum Zeno effect) is investigated. Using asymptotic analysis, the system is found to evolve unitarily in a pro…
