Ermakov-Lewis angles for one-parameter supersymmetric families of Newtonian free damping modes.
We apply the Ermakov-Lewis procedure to the one-parameter damped modes y recently introduced by Rosu and Reyes, which are related to the common Newtonian free damping modes y by the general Riccati solution [H. C. Rosu and M. Reyes, Phys. Rev. E 57, 4850 (1998)]. In particular, we calculate and plot the angle quantities of this approach that can help to distinguish these modes from the common y modes.
