For a class of mixed two -qubit states we show that it is not possible to discriminate between states violating or non - violating Bell - CHSH inequalities, knowing only their entanglement and mixedness. For a large set of possible values of these qu

In this paper, we have studied tunneling effect of the spin-2 Bose condensate driven by external magnetic field. We find that the population transfers among spin-0 and spin-$\pm1$, spin-0 and spin-$\pm2$ exhibit the step structure under the external

The frequency spectrum of surface waves propagating on a semibounded non-relativistic magnetized plasma jet in the ion-acoustic frequency region is obtained. In addition, the effect of an external magnetic field on the modulation of a non-relativisti

We present the experimental results of measurements of the overlap of both pure and mixed polarization states of photons. The fidelity and purity of mixed states were also measured. The experimental apparatus exploits the fact that a beam splitter ca

A classical fluid description is used to investigate nonlinear interactions between an electron-type neutrino beam and a relativistic collisionless unmagnetized electron–positron plasma. It is shown that during the interaction a large amplitude wak

The frequency spectra and damping rate of surface waves propagating along a plasma jet are obtained in both of high and low frequency region. Finally, the penetration of the static field in the plasma jet and filamentation of a subsonic plasma jet is

Bell's inequality violation is related to the breakdown of symmetry of photonic field states. The states allowing the violation are characterized by a parameter γ associated with the interaction of the nonlinear medium and radiation. The violation i

The ionization with temperature of weakly bound muonium atoms in undoped CdS has been studied using the technique of muon spin relaxation in a transverse magnetic field of 10 mT. For this atom the Coulomb binding energy between the muon and the elect

We explore a new type of optical bistability (OB) based on electromagnetically induced grating (EIG) and discuss the factors that affect the instability of this system. The stability of each branch of the solution is analyzed.

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
