Signal velocity is calculated in a medium with negative group delay (NGD). By accounting for the medium and the detector noise sources, the time varying probability of error at the detector [ Pe ( t ) ] is evaluated in the NGD channel and a normal di

A numerical model of spontaneous decay continuously monitored by a distant detector of emitted particles is constructed. It is shown that there is no quantum Zeno effect in such quantum measurement if the interaction between emitted particle and dete

We consider the loophole due to detector inefficiency in Cabello's argument on Bell's theorem without inequalities for the three-qubit system. It is shown that detectors with low efficiencies can be employed in physical tests. In addition, the mixed

In muon spin relaxation studies on the S = 12 double chain system KCuCl3, which is thought to have a spin singlet ground state with a finite spin gap, we found that the muon spin becomes strongly depolarized below 20 K. Under a longitudinal magnetic

The nonlinear propagation of an intense neutrino flux in an electron-positron plasma with equilibrium density and magnetic field inhomogeneities is considered. It is found that the neutrinos are nonlinearly coupled with electrostatic and electromagne

The nonlinear scattering of an intense flux of neutrinos by plasma oscillations is formulated in terms of the ponderomotive force description. Starting with the refractive index of electron neutrinos we show that the neutrinos exert a force on the el

A method to detect 8B solar neutrinos is proposed using the charge current reaction νe19F with a hexafluorobenzene scintillation detector. The main advantage of the detector is the possibility of identifying neutrino events by a delayed coincidence

We propose that the intense neutrino flux emitted by the core of a supernova generates parametric decay instabilities (neutrinos generate plasma waves and lower energy neutrinos) in the surrounding stellar envelope. The process is analogous to the st

We show how, in the Bohm model, the significance to be attached to the readings of a detector depends on the context in which it is used.

The conversion of electron neutrinos into either a tau or muon neutrino in a dense plasma, such as in the solar interior, is shown to be described by the Weber equation. We show that the problem is related to propagation through a potential barrier a
