Lieb-Robinson bounds for spin-boson lattice models and trapped ions Junemann, J. Cadarso, A. Pérez García, David Bermúdez Carballo, Alejandro García Ripoll, Juan José 517 Quantum simulation Systems Análisis matemático 1202 Análisis y Análisis Funcional We derive a Lieb-Robinson bound for the propagation of spin correlations in a model of spins interacting through a bosonic lattice field, which satisfies a Lieb-Robinson bound in the absence of spin-boson couplings. 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. Unión Europea.
