Generalized Wavefunctions for Correlated Quantum Oscillators III: Chaos, Irreversibility

In this third of a series of four articles, we continue the study of the representations of the dynamical transformations of systems of correlated quantized oscillators. By including generalized wave function solutions to Schrödinger’s equation (belonging to a rigged Hilbert space), and by considering the algebra of observables as a whole, the presence of Devaney chaos, hyperbolic quasi-invariant measures, torus actions, ergodicity and entropy generation associated to the non-invertible decay of Gamow vectors and their associated to Breit-Wigner resonances is shown. A weak (local) form of the second law of thermodynamics is demonstrated through the decay of resonances. Both coherence formation and decoherence (decay) are associated with irreversibility and may be associated with entropy growth, which is due to the dynamical time evolution of resonances. Hilbert space is the manifold of stationary states. There is a fractal structure associated with dynamical time evolution of resonances in the space of generalized states, and the statistical nature of the exponential decay may be identified with quasi-trapping. Equilibrium states may be regarded as strange attractors with respect to dynamical time evolution.
