On the exit statistics theorem of many particle quantum scattering
Detlef Duerr, Stefan Teufel
We review the foundations of the scattering formalism for one particle potential scattering and discuss the generalization to the simplest case of many non interacting particles. W…
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…
Quantum spacetime without observers: ontological clarity and the conceptual foundations of quantum gravity
Sheldon Goldstein, Stefan Teufel
We explore the possibility of a Bohmian approach to the problem of finding a quantum theory incorporating gravitational phenomena. The major conceptual problems of canonical quantu…
