Quantum mechanical perturbation theory in terms of characteristic functions
A quantum mechanical perturbation theory, for finite dimensional cases, based not on the perturbed Hamiltonian operator itself, but on the characteristic function f(z,λ) = det|z-H(λ)| is developed. A perturbation hierarchy in terms of derivatives of the characteristic function is constructed. From t...
