Lorentz violation has been shown to occur in Planck scale physics. Since neutrino oscillation experiments are natural interferometers, they may be sensitive to small space-time effect, such as Lorentz violation. The sensitivity is comparable to precision optical measurements (10E-19 GeV). Thus, neutrino oscillations may be the first place where we see Lorentz and CPT violation.

The MiniBooNE neutrino oscillation experiment published electron and anti-electron neutrino appearance oscillation results that cannot be understood within the accepted three-massive-neutrinos oscillation model.

In this talk, I will introduce Lorentz violation and Lorentz violating neutrino oscillations. And I examine whether the MiniBooNE data may be explained through a Lorentz violation model. Then, I will discuss Lorentz violation analysis results on Double Chooz reactor oscillation experiment. Finally, I will show a future prospective of the best Lorentz violation test on the neutrino sector through the astrophysical very high-energy neutrinos at IceCube.
