By decomposing SU(2) gauge potential in four-dimensional Euclidean SU(2) Yang-Mills theory in a new way,we find that the instanton number related to the isospin
We propose a new multiparty simultaneous quantum direct communication scheme based on Green-Hoe-Zeilinger(GHZ)states and dense coding.For achieving high efficie
We investigate the multi-symplectic Euler-box scheme for the nonlinear Schr(o)dinger equation.Two new simple semi-explicit scheme are derived.A composition sche
