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…
Generalized solutions and distributional shadows for Dirac equations
Guenther Hoermann, Christian Spreitzer
We discuss the application of recent results on generalized solutions to the Cauchy problem for hyperbolic systems to Dirac equations with external fields. In further analysis we f…
Wave equations and symmetric first-order systems in case of low regularity
Clemens Hanel, Günther Hörmann, Christian Spreitzer +1
We analyse an algorithm of transition between Cauchy problems for second-order wave equations and first-order symmetric hyperbolic systems in case the coefficients as well as the d…
Symmetric hyperbolic systems in algebras of generalized functions and distributional limits
Guenther Hoermann, Christian Spreitzer
We study existence, uniqueness, and distributional aspects of generalized solutions to the Cauchy problem for first-order symmetric (or Hermitian) hyperbolic systems of partial dif…
