Abstract

The classical Coriolis force finds its quantum analogue in the difference Σ(t)=H(t)G(t)\Sigma(t)=H(t)-G(t) where the ``true'', observable Hamiltonian H(t)H(t) represents the instantaneous energy. The other, ``false'' Hamiltonian G(t)G(t) generates the time-evolution of wave functions. Whenever Σ(t)0\Sigma(t)\neq 0, quantum mechanics acquires an interaction-picture form. Then, the time-evolution of every observable is generated by the Coriolis operator Σ(t)\Sigma(t) ({\it alias} ``Heisenberg'' Hamiltonian) itself. In the paper a sequence of alternative formulae for Σ(t)\Sigma(t) is derived under the assumption of an NN-term factorization of the Dyson-map operator Ω(t)\Omega(t) (defined as converting a preselected quasi-Hermitian H(t)H(t) into its conventional self-adjoint avatar). It is shown that in the resulting innovative formalism called ``factorization-based non-Hermitian interaction picture'' (FNIP) one has a choice between N+1N+1 alternative forms of the description of quantum dynamics, one of which may prove, for the underlying quantum system, optimal. For illustration, the ``wrong-sign'' anharmonic oscillator model is recalled.
