Dynamical quantum phase transitions (DQPTs) represent a counterpart innon-equilibrium quantum time evolution of thermal phase transitions atequilibrium, where real time becomes analogous to a control parameter such astemperature. In quenched quantum systems, recently the occurrence of DQPTs hasbeen demonstrated, both with theory and experiment, to be intimately connectedto changes of topological properties. Here, we contribute to broadening thesystematic understanding of this relation between topology and DQPTs tomulti-orbital and disordered systems. Specifically, we provide a detailedergodicity analysis to derive criteria for DQPTs in all spatial dimensions, andconstruct basic counter-examples to the occurrence of DQPTs in multi-bandtopological insulator models. As a numerical case study illustrating ourresults, we report on microscopic simulations of the quench dynamics in theHarper-Hofstadter model. Furthermore, going gradually from multi-band todisordered systems, we approach random disorder by increasing the (super) unitcell within which random perturbations are switched on adiabatically. Thisleads to an intriguing order of limits problem which we address by extensivenumerical calculations on quenched one-dimensional topological insulators andsuperconductors with disorder.
