There are no abnormal solutions of the Bethe−-Salpeter equation in the static model

The four-point Green's function of static QED, where a fermion and an antifermion are located at fixed space positions, is calculated in covariant gauges. The bound state spectrum does not display any abnormal state corresponding to excitations of the relative time. The equation that was established by Mugibayashi in this model and which has abnormal solutions does not coincide with the Bethe$-$Salpeter equation. Gauge transformation from the Coulomb gauge also confirms the absence of abnormal solutions in the Bethe$-$Salpeter equation.Comment: 11 pages, late

Formation of two-dimensional weak localization in conducting Langmuir-Blodgett films

We report the magnetotransport properties up to 7 T in the organic highly conducting Langmuir-Blodgett(LB) films formed by a molecular association of the electroactive donor molecule bis(ethylendioxy)tetrathiafulvalene (BEDO-TTF) and stearic acid CH$_3$(CH$_2$)$_{16}$COOH. We show the logarithmic decrease of dc conductivity and the negative transverse magnetoresistance at low temperature. They are interpreted in the weak localization of two-dimensional (2D) electronic system based on the homogeneous conducting layer with the molecular size thickness of BEDO-TTF. The electronic length with phase memory is given at the mesoscopic scale, which provides for the first time evidence of the 2D coherent charge transport in the conducting LB films.Comment: 5 pages, 1 Table and 5 figure

Bell-states diagonal entanglement witnesses for relativistic and non-relativistic multispinor systems in arbitrary dimensions

Two kinds of Bell-states diagonal (BSD) entanglement witnesses (EW) are constructed by using the algebra of Dirac $\gamma$ matrices in the space-time of arbitrary dimension $d$, where the first kind can detect some BSD relativistic and non-relativistic $m$-partite multispinor bound entangled states in Hilbert space of dimension $2^{m\lfloor d/2\rfloor}$, including the bipartite Bell-type and iso-concurrence type states in the four-dimensional space-time ($d=4$). By using the connection between Hilbert-Schmidt measure and the optimal EWs associated with states, it is shown that as far as the spin quantum correlations is concerned, the amount of entanglement is not a relativistic scalar and has no invariant meaning. The introduced EWs are manipulated via the linear programming (LP) which can be solved exactly by using simplex method. The decomposability or non-decomposability of these EWs is investigated, where the region of non-decomposable EWs of the first kind is partially determined and it is shown that, all of the EWs of the second kind are decomposable. These EWs have the preference that in the bipartite systems, they can determine the region of separable states, i.e., bipartite non-detectable density matrices of the same type as the EWs of the first kind are necessarily separable. Also, multispinor EWs with non-polygon feasible regions are provided, where the problem is solved by approximate LP, and in contrary to the exactly manipulatable EWs, both the first and second kind of the optimal approximate EWs can detect some bound entangled states.

DEFECT CLUSTER FORMATION IN NEUTRON IRRADIATED SUS316 AND JPCA DOPED WITH ^<10>B

A SUS316 and a JPCA were irradiated at 643, 793 and 873K to 30 dpa in FFTF (Fast Flux Test Facility)/MOTA (Material Open Test Assembly) during its cycle 11 operation to investigate the effect of high helium generation rate on cavity formation under neutron irradiation. In FFTF/MOTA, (n, α) reaction of boron isotope can produce a large amount of helium atoms in SUS316 and JPCA. In all of temperature conditions, cavities were observed in both alloys with different contens of ^B. In view of number density, size distribution and mean size of cavity in the alloys, the effect of helium generation rate on the nuclation and the growth of cavity is discussed

Einstein-Podolsky-Rosen correlation in gravitational field

For quantum communication in a gravitational field, the properties of the Einstein-Podolsky-Rosen (EPR) correlation are studied within the framework of general relativity. Acceleration and gravity are shown to deteriorate the perfect anti-correlation of an EPR pair of spins in the same direction, and apparently decrease the degree of the violation of Bell's inequality. To maintain the perfect EPR correlation and the maximal violation of Bell's inequality, observers must measure the spins in appropriately chosen different directions. Which directions are appropriate depends on the velocity of the particles, the curvature of the spacetime, and the positions of the observers. Near the event horizon of a black hole, the appropriate directions depend so sensitively on the positions of the observers that even a very small uncertainty in the identification of the observers' positions leads to a fatal error in quantum communication, unless the observers fall into the black hole together with the particles.Comment: 22 pages, 3 figures, several minor revisions are mad
