Abstract

Abstract Quantum energies for Caldirola–Kanai Hamiltonian systems with and without a singular perturbation are investigated in coherent states on the basis of invariant operator theory. Our results are compared with those of several different approaches from various angles. Further, the advantages of our method over that adopted in the previous researches are addressed in detail.
