Description:
Author(s): Norbert Schuch, Sarah K. Harrison, Tobias J. Osborne, and Jens Eisert We study the speed at which information propagates through systems of interacting quantum particles moving on a regular lattice and show that for a certain class of initial conditions there exists a maximum speed of sound at which information can propagate. Our argument applies equally to quantum sp... [Phys. Rev. A 84, 032309] Published Thu Sep 08, 2011
