In this second of a series of articles, a pair of quantized free oscillators is transformed into a resonant system of coupled oscillators by analytic continuation which is performed algebraically by the group of complex symplectic transformations, creating dynamical representations of numerous semi-groups from the Hamiltonian free system. The free oscillators are the quantum analogue of action angle variable solutions for the coupled oscillators and quantum resonances, including Breit-Wigner resonances. Among the exponentially decaying Breit-Wigner resonances are hamiltonian systems in which energy transfers from one oscillator to the other. There are significant mathematical constraints in order that complex spectra be accommodate in a wel...
