Adiabatic phase variation for optical Gaussons

This paper studies the adiabatic phase variation of optical Gaussons in the presence of perturbation terms. The modified conservation law of phase variation is used to carry out this analysis.

► The nonlinear Schrodinger's equation with log law nonlinearity is studied.
► The perturbation terms are taken into consideration.
► The phase conservation law is taken into consideration.
► The adiabatic phase variation in the presence of perturbation terms is obtained.
