Criteria for existence and stability of soliton solutions of the cubic-quintic nonlinear Schrodinger equation
A subset of the soliton solutions of the cubic-quintic nonlinear Schrodinger equation (NLSE) is presented in analytical form. General criteria for existence are expressed in terms of the parameters of the NLSE. The normalized momentum entering the stability criterion is evaluated explicitly.
