Designing quantum protocols with unit success probability is highly desirable from a viewpoint of the overall resource cost. In this work, we propose a new deterministic protocol for joint remote preparation of the most general two-qubit state using the s... see more

Starting with the generalized electromagnetic (and gravi-magnetic) fields of dyons (and grvito-dyons), the octonion generalization of U(1)×SU(2)U(1)\times SU(2) gauge theories of dyons (and grvito-dyons) has been developed in a consistent way. The resembl... see more

The neutrality effects on the phase structure of the linear sigma model with the non-standard symmetry breaking term is systematically studied by means of the Cornwall-Jackiw-Tomboulis effective potential. The latter quantity is calculated in the improved... see more

The half-filled isotropic degenerate two-band Hubbard model is studied within coherent potential approximation. The model is characterized by an Ising-type Hund’s exchange coupling, intra- and inter-orbital Coulomb parameters. We found that the band de... see more

The undoped and transition metal (Co, Ni)-doped TiO2_{2} nanowires were synthesized by simple and low cost solvothermal method and their microstructure and optical properties were investigated based on the fixed doping concentration of 1 at.%. T... see more

Based on the nonlinearity of the nonlinear optical coupler (NOC) and the amplifying capacity of the backward Raman fiber amplifier (PBRFA), a new optical system to compress the optical pulse (optical pulse self-compressor: OPSC) is proposed. Using the exp... see more

Prototype double-sided silicon strip detectors (DSSDss) of 300 µ\mu m thickness produced at PTI St. Petersburg (Russia) were tested for the use as position sensitive, ?E\Delta E and E detectors for tracking and particle identification in the EXL (EXoti... see more

Back-scattering gamma-rays have been extensively used for years as a nondestructive tool for inspecting the materials in different fields of the economy. The intensities of Compton scattering gamma-rays from the scattering medium strongly depend on its el... see more

Study of nuclear reactions using radioactive beams at low energy plays an important role in nuclear astrophysics and nuclear structure. The trajectory of particle beams can be obtained by using an active gas target, multiple-sampling and tracking proporti... see more
