Abstract:In coherent-state representation, we introduce a concise approach to dealwith the Jaynes-Cummings(JC)model, in which the purely quantum mechanical problem is reduced to the solution of some differential equations. It is shown that this ap-proach can not o
Abstract:In this paper, a universal complex number solution of incompressiblefluid Navier-Stokes equations was derived by introducing universal complex numbervariable,i.e., the velocity field and pressure field indicated with the universal complexnumber variable.
