Lieb-Robinson correlation function for long disordered transverse-field Ising chains

Physical Review Research
The Lieb-Robinson correlation function can be used to characterize the propagation of quantum information in Ising chains. Considerable work has been done to establish bounds on this correlation function in various circumstances.
