Spin interaction of non-relativistic neutrons with an ultrashort laser pulse
Peter Christian Aichelburg, Christian Spreitzer
The non-relativistic Pauli equation is used to study the interaction of slow neutrons with a short magnetic pulse. In the extreme limit, the pulse is acting on the magnetic moment…

Modeling Schrödinger equation diffraction with generalized function potentials and initial values
Günther Hörmann, Ljubica Oparnica, Christian Spreitzer
We discuss spectral properties of a regularization approach to a Schrödinger equation set-up for the diffraction of a quantum particle at almost planar patterns. Physically meaning…

Green Operators in Low Regularity Spacetimes and Quantum Field Theory
Guenther Hoermann, Yafet Sanchez Sanchez, Christian Spreitzer +1
In this paper we develop the mathematics required in order to provide a description of the observables for quantum fields on low-regularity spacetimes. In particular we consider th…
