The exclusive production of one μ+μ− pair in collisions of two ultra-relativistic nuclei is considered. We present the simple method for calculation of the Born cross section for this process. Then we found that the Coulomb corrections to this cross section (which correspond to multi-photon exchange of the produced μ with nuclei) are small while the unitarity corrections are large. This is in s...

The purpose of this paper is to introduce the unitary limit as applied in systems cold atoms into collective states heavy and even-even nuclei identify a related physical example. This accompanied by determination observables conformal symmetry nuclear structure. A Hamiltonian defined that governs scattering process an incident pair two slow neutrons onto heavy, target nucleus framework Interac...

In this paper we present a novel technique for integrating lexical-semantic knowledge in systems for learning textual entailment recognition rules: the typed anchors. These describe the semantic relations between words across an entailment pair. We integrate our approach in the cross-pair similarity model. Experimental results show that our approach increases performance of cross-pair similarit...

Electrons on the liquid helium surface form an extremely clean two dimensional system where different plasmon-excitations can coexist. Under a magnetic field time reversal symmetry is broken and all bulk magneto-plasmons become gaped at frequencies below cyclotron resonance while chiral one edge appear perimeter. We theoretically show that presence of homogeneous density gradient in electron ga...

We investigate two-color photon correlations in the light emitted by two strongly driven, interacting two-level emitters. The are interpreted introducing collective dressed states picture, which allows us to describe both bunching and antibunching based on allowed prohibited transitions. At odds from weakly emitters, strong interaction lifts degeneracy of energy differences between different st...
