Space-adiabatic Decoupling to All Orders
Gianluca Panati, Herbert Spohn, Stefan Teufel
A systematic perturbation scheme is developed for approximate solutions to the time-dependent Schroedinger equation with a space-adiabatic Hamiltonian. For a particular isolated en…

Space-Adiabatic Perturbation Theory
Gianluca Panati, Herbert Spohn, Stefan Teufel
We study approximate solutions to the Schrödinger equation $i\epsi\partialψ_t(x)/\partial t = H(x,-i\epsi\nabla_x) ψ_t(x)$ with the Hamiltonian given as the Weyl quantization of th…
