    The smooth and nonsmooth travelling wave solutions in a nonlinear wave equation

    The travelling wave solutions (TWS) in a class of P.D.E. is studied. The travelling wave equation of this P.D.E. is a planar cubic polynomial system in three-parameter space. The study for TWS became the topol...

    Laser-assisted electron capture by a fast proton from a hydrogen atom

    The first Born approximation is used to study the laser-assisted electron capture by a fast proton from a hydrogen atom. The laser modification on differential cross section peaks sharply in the forward direct...

    A new description of field: the pseudo-Hamiltonian description

    A new description of field, the pseudo Hamilton description, is proposed. To a physical field, we may introduce the pseudoconjugate momentum tensor and the pseudo-Hamiltonian. The pseudo-Hamiltonian is a scala...
