We apply these bounds to a system of trapped ions and find that the propagation of spin correlations, as mediated by the phonons of the ion crystal, can be faster than the regimes currently explored in experiments. We propose a scheme to test the bounds by measuring retarded correlation functions via the crystal fluorescence. 0031-9007 10.1103/PhysRevLett.111.230404 https://hdl.handle.net/20.500.14352/33471 http://journals.aps.org/prl/pdf/10.1103/PhysRevLett.111.230404 http://www.aps.org/ http://arxiv.org/pdf/1307.1992v2.pdf Lieb-Robinson bounds for spin-boson lattice models and trapped ions
