Completely Quantized Collapse and Consequences
... CQC facilitates that demonstration (which can be converted to CSL language with less transparency). Because the ensemble vector evolution in CQC is a Hamiltonian evolution, the Hamiltonian is a conserved energy associated with the ensemble. The Hamiltonian does not commute with W (x, t) since it is ...

6 Theory of the topological Anderson insulator
... We will now show that disorder can push the phase transition to positive values of m, which is the hallmark of a TAI. Qualitatively, the mechanism is as follows. Elastic scattering by a disorder potential causes states of definite momentum to decay exponentially as a function of space and time. The ...

Multiscale theory of finite-size Bose systems: Implications for collective

The QC-wide processes are either collective 共e.g., rotations, coherent density waves, or shape oscillations兲 or migrations of particlelike disturbances across the QC 共i.e., the coordinated motion of a given particle and a set of oth ...
