Threshold between short and long-range potentials for non-local Schr\"odinger operators

Abstract

We develop scattering theory for non-local Schr\"odinger operators defined by functions of the Laplacian that include its fractional power (Δ)ρ(-\Delta)^\rho with 0<ρ10<\rho\leqslant1. In particular, our function belongs to a wider class than the set of Bernstein functions. By showing the existence and non-existence of the wave operators, we clarify the threshold between the short and long-range decay conditions for perturbational potentials.
