Quintic Nonlinear Schrödinger Equation

The coupled cubic-quintic nonlinear Schrödinger (CQNLS) equation is a universal mathematical model describing many physical situations, such as nonlinear optics and Bose–Einstein condensate. In this paper, in order to simplify the process of similar analysis with different forms of the coupled CQNLS equation, this dynamic system is extended to a time-space scale based on the Lax pair and zero curvature equation. Furthermore, Darboux transformation of the coupled CQNLS dynamic system on a time-space scale is constructed, and the N-soliton solution is obtained. These results effectively combine the theory of differential equations with difference equations and become a bridge connecting continuous and discrete analysis.

Approach Zero

The difference between intensity interferometry and measurements of two-particle momentum correlations in heavy-ion collisions is discussed. These approaches are generally used to estimate the time-space scale of fireballs produced in heavy-ion collisions. It is inferred that the C(q inv ) function will increase with the decrease of q inv for both bosons and fermions, if q inv does not approach zero.
