Abstract Among the information provided by high energy neutrinos, a promising possibility is to analyze effects of Violation Equivalence Principle (VEP) on neutrino oscillations. We recently released IceCube data atmospheric fluxes under assumption VEP and obtain updated constraints parameter space with benchmark choice that neutrinos different masses couple strengths gravitational field. In th...

We give a general overview of various flavours the equivalence principle in classical and quantum physics, with special emphasis on so-called weak principle, contrast its validity mechanics versus field theory. also discuss generalisation to theory gravity. Our analysis suggests that only strong can be considered fundamental enough generalised gravity context since all other hold approximately ...

We describe a geometric and symmetry-based formulation of the equivalence principle in non-relativistic physics. It applies both on classical quantum levels states that Newtonian potential can be eliminated favor curved time-dependent spatial metric. is this requirement forces gravitational mass to equal inertial mass. identify symmetry responsible for as remnant time-reparameterization relativ...
