 For interacting quantum systems, Schrödinger’s equation is no longer valid and one typically turns to so-called master equations to describe evolution (Davies 1976). Such equations typically have nonseparable Hamiltonians. In general, the time evolution of the components of such interacting systems is not unitary meaning that there is no formal prohibition against SDIC. Moreover, an important contrast between isolated and interacting quantum systems is that while the former have discrete energy spectra, the latter have continuous spectra. A continuous energy spectrum is characteristic of classical systems. Nevertheless, work in interacting quantum systems largely has only uncovered the same kinds of universal statistical characteristics of energy spectra and fluctuations as found in isolated systems (e.g., Guhr, Müller-Groeling and Weidenmüller 1998; Ponomarenko, et al. 2008; Filikhin, Matinyan and Vlahovic 2011).
