Interaction of Coupled Higher Order Nonlinear SCHR\"Odinger Equation Solitons

The novel inelastic collision properties of two-soliton interaction for an $n$-component coupled higher order nonlinear Schr\"odinger equation are studied. Some interesting features of three soliton interactions, related to the integrability of the $n$-component coupled higher order nonlinear Schr\"odinger equation are also discussed.Comment: 6 pages, 4 figures, revtex

QCD phase transition in rotaing neutron star, Neutrino beaming and Gamma-ray bursters

We have studied the emission of neutrinos from a rotating hybrid star. We find that the emission is predominantly confined to a very small angle, provided the core of the star is in a mixed phase of quarks and hadrons and the size of such a mixed phase is small. Annihilation of neutrinos to produce gamma rays has been discussed. The estimated duration of the burst is found to be within the observational range.Comment: Modified manuscript with 9 pages including 3 ps figures, Accepted for publication in Phys. Lett.
