Query: Constraining the Violation of Equivalence Principle with IceCube
  Atmospheric Neutrino Data   The recent high-statistics high-energy atmospheric neutrino data collected by
IceCube open a new window to probe new physics scenarios that are suppressed in
lower energy neutrino experiments. In this paper we analyze the IceCube
atmospheric neutrino data to constrain the Violation of Equivalence Principle
(VEP) in the framework of three neutrinos with non-universal gravitational
couplings. In this scenario the effect of VEP on neutrino oscillation
probabilities can be parametrized by two parameters $\Delta \gamma_{21}\equiv
\gamma_2-\gamma_1$ and $\Delta\gamma_{31}\equiv \gamma_3-\gamma_1$, where
$\gamma_i$'s denote the coupling of neutrino mass eigenstates to gravitational
field. By analyzing the latest muon-tracks data sets of IceCube-40 and
IceCube-79, besides providing the 2D allowed regions in
$(\phi\Delta\gamma_{21},\phi\Delta\gamma_{31})$ plane, we obtain the upper
limits $|\phi\Delta\gamma_{21}| < 9.1\times 10^{-27}$ (at 90\% C.L.) which
improves the previous limit by $\sim4$ orders of magnitude and
$|\phi\Delta\gamma_{31}| \lesssim 6\times 10^{-27}$ (at 90\% C.L.) which
improves the current limit by $\sim1$ order of magnitude. Also we discuss in
detail and analytically the effect of VEP on neutrino oscillation
probabilities.
