Ermakov-Lewis invariant in Koopman-von Neumann mechanics
Published 11 Jun 2020 in quant-ph and physics.class-ph | (2006.06489v1)
Abstract: In the paper Sci. Rep. 8, 8401 (2018), among other things, the Ermakov-Lewis invariant was constructed for the time dependent harmonic oscillator in Koopman-von Neumann mechanics. We point out that there is a simpler method that allows one to find this invariant.
