Abstract: I will introduce a non-relativistic limit of physics in AdS, retaining a harmonic Newtonian gravitational potential from the AdS curvature, and relate it to the spectrum and correlation functions of a dual CFT. This allows non-perturbative control for studying interesting subjects including the flat spacetime limit and resonances. Finally we will study the CFT Lorentzian inversion formula in this limit, obtaining a novel dispersion relation in non-relativistic quantum mechanics.
