For periodic and approximately periodic systems, the answer is yes, as we show in this work. Our analytical approach, which we call the Quantum Spectral Method, is based on a novel application of Bohr's correspondence principle, obtaining non-perturbative classical dynamics as the classical limit of quantum matrix elements. A major application of our method is the calculation of self-force as the classical limit of atomic radiative transitions. We demonstrate this by calculating an adiabatic electromagnetic inspiral, along with its associated radiation, at all orders in the multipole expansion.

Abstract

Abstract: Can classical systems be described analytically at all

orders in their interaction strength? For periodic and approximately

periodic systems, the answer is yes, as we show in this work. Our

analytical approach, which we call the Quantum Spectral Method, is

based on a novel application of Bohr's correspondence principle,

obtaining non-perturbative classical dynamics as the classical limit

of quantum matrix elements. A major application of our method is the

calculation of self-force as the classical limit of atomic radiative

transitions. We demonstrate this by calculating an adiabatic

electromagnetic inspiral, along with its associated radiation, at all

orders in the multipole expansion.
