Previous calculations of stretched exponential decay in disordered systems have been extended to cover situations where there is backtransfer and leakage in the relaxation channels. Results are obtained for the relaxation of the macroscopic parameter in situations where the channels are governed...

The new scheme employed (throughout the “thermodynamic phase space”), in the statistical thermodynamic investigation of classical systems, is extended to quantum systems. Quantum Nearest Neighbor Probability Density Functions (QNNPDF's) are formulated (in a manner analogous to the classical...
