    • New Anomalous Lieb-Robinson Bounds in Quasiperiodic XY Chains 

      Damanik, David; Lemm, Marius; Lukic, Milivoje; Yessen, William (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 ...
