Query: Search for Lorentz Violation Using High-Energy Atmospheric Neutrinos In
  IceCube   High-energy atmospheric neutrinos observed by the IceCube Neutrino
Observatory are extremely sensitive probes of Lorentz violation (LV). Here we
report the result of analyzing two years of IceCube data in the search for LV.
This analysis places some of the strongest constraints on LV when considering
high-dimensional operators.
