Hc. Rosu et Pb. Espinoza, Ermakov-Lewis angles for one-parameter supersymmetric families of Newtonian free damping modes - art. no. 037603, PHYS REV E, 6303(3), 2001, pp. 7603
We apply the Ermakov-Lewis procedure to the one-parameter damped modes (y)
over tilde 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 calcu
late and plot the angle quantities of this approach that can help to distin
guish these modes from the common y modes.
