Quantum motion of electrons in topologically distorted crystals
... of the ideal lattice and consequently leads to a breakdown of the Bloch theorem for electronic quantum states. Outside the core region of such topological defects the lattice locally looks perfect but globally is distorted at arbitrary distances from the core. One therefore expects that sufficiently ...

If, on the other hand, a coherent implementation of gain and loss is not feasible, either because of fundamental quantum limits or current technological limits, then it is important to take into account additional effects ...
