Asymptotic Observables in the N-Body Quantum Long Range Scattering
- 152 Downloads
Certain observables converge in the Heisenberg picture to a limit as time goes to ±∞. These limits, which may be called asymptotic observables, are especially interesting in the context of long range N-body Schrödinger operators. By studying certain natural classes of asymptotic observables one can get a lot of insight in the quantum N-body scattering.
