• #### New Anomalous Lieb-Robinson Bounds in Quasiperiodic XY Chains ﻿

(2014)
We announce and sketch the rigorous proof of a new kind of anomalous (or sub-ballistic) Lieb-Robinson (LR) bound for an isotropic XY chain in a quasiperiodic transversal magnetic field. Instead of the usual effective light ...
