Abstract: We show that the entropy of entanglement is sensitive to the coherent quantum phase transition between normal and super-radiant regions of a system of a finite number of three-level atoms interacting in a dipolar approximation with a one-mode electromagnetic field. The atoms are treated as semi-distinguishable using different cooperation numbers and representations of SU(3), variables...

New paradigms for optical physics emerge from atoms trapped in one and two-dimensional dielectric waveguides [1,2]. Photons propagating in the guided modes of the waveguides can mediate long-range atom-atom interactions. In a complimentary fashion, photon-photon interactions can arise by way of the underlying lattice of atoms. This new future of atom nanophotonics has the potential to provide t...

We extend our analysis of the effects of the interplay of quantum phases and nonlinearity to address saturation effects in small quantum systems. We find that initial phases dramatically control the dependence of self-trapping on initial asymmetry of quasiparticle population and can compete or act with nonlinearity as well as saturation effects. We find that there is a minimum finite saturation...

objectives: the present study was carried out to investigate the relationship between different lunar phases and the occurrence of overdose attempted suicide. method: the study was carried out for a period of three lunar years (shaban 1416 to shaban 1419) with patients admitted to the intoxication emergency clinic at imam reza hospital in mashad. in this research, 13422 cases of suicide attempt...

this new method which is worked out in isfahan university of technology, makes it possible to analyze the phases quantitatively in minerals and powdered materials by x ray diffraction and without any reference material. to identify n unknown phases, n different combinations of phases, from fine and coarse fractions, or etc., must be obtained. amorphous phases should not exist. intensity ratios ...

α-Na3NpO4 and α-Na3PuO4 exhibit an orthorhombic structure (Z = 8), in space group Fmmm, with lattice parameters a = 13.352(2) Å, b = 9.629(2) Å, and c = 6.673(2) Å for the neptunium compound, and a = 13.302(2) Å, b = 9.634(2) Å, and c = 6.651(2) Å for the plutonium analogue. The corresponding structure has been solved ab initio as no structural analogue could be found in the literature. The pen...

We propose a entanglement generating set for a general multipartite state based on the of concurrence. In particular, we show that concurrence for general multipartite states can be constructed by different classes of local operators which are defined by complement of positive operator valued measure on quantum phases. The entanglement generating set consists of different classes of entanglemen...

M phase induction in eukaryotic cell cycles is associated with a burst of protein phosphorylation, primarily at serine or threonine followed by proline (S/TP motif). The mitotic phosphoprotein antibody MPM-2 recognizes a significant subset of mitotically phosphorylated S/TP motifs; however, the required surrounding sequences of and the key kinases that phosphorylate these S/TP motifs remain to ...

The Aharonov-Anandan phase is introduced from a physical point of view. Without reference to any dynamical equation, this phase is formulated by defining an appropriate connection on a specific fibre bundle. The holonomy element gives the phase. By introducing another connection, the Pancharatnam phase formula is derived following a different procedure.
