Comment on Demystifying the constancy of the Ermakov-Lewis invariant for a time-dependent oscillator

Abstract

We show that a simple modification of the Lagrangian proposed by Padmanabhan in the paper [Mod. Phys. Lett. A 33, 1830005 (2018), arXiv:1712.07328] leads to the most general dynamical invariant in [Ray and Reid, Phys. Lett. A 71, 317 (1979)]
