Direct experimental evidence of free fermion antibunching
M. Iannuzzi, A. Orecchini, F. Sacchetti +2
Fermion antibunching was observed on a beam of free noninteracting neutrons. A monochromatic beam of thermal neutrons was first split by a graphite single crystal, then fed to two…
Optimization of a Neutron-Spin Test of the Quantum Zeno Effect
Paolo Facchi, Yoichi Nakaguro, Hiromichi Nakazato +3
A neutron-spin experimental test of the quantum Zeno effect (QZE) is discussed from a practical point of view, when the nonideal efficiency of the magnetic mirrors, used for filter…
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…
Quantum chaos induced by measurements
P. Facchi, S. Pascazio, A. Scardicchio
We study the dynamics of a "kicked" quantum system undergoing repeated measurements of momentum. A diffusive behavior is obtained for a large class of Hamiltonians, even when the d…
Wigner function and coherence properties of cold and thermal neutrons
P. Facchi, A. Mariano, S. Pascazio
We analyze the coherence properties of a cold or a thermal neutron by utilizing the Wigner quasidistribution function. We look in particular at a recent experiment performed by Bad…
