Scattering Theory for Open Quantum Systems

J. Behrndt, M. M. Malamud, H. Neidhardt

Quantum systems which interact with their environment are often modeled by maximal dissipative operators or so-called Pseudo-Hamiltonians. In this paper the scattering theory for s…

Scattering matrices and Weyl functions

Jussi Behrndt, Mark M. Malamud, Hagen Neidhardt

For a scattering system ${A_{Θ}, A_{0}}$ consisting of selfadjoint extensions $A_{Θ}$ and $A_{0}$ of a symmetric operator $A$ with finite deficiency indices, the scattering matrix $\{S_\g…
