Generalised Point Interactions for the Radial Schrodinger Equation via Unitary Dilations
C. J. Fewster
We present an inverse scattering construction of generalised point interactions (GPI) -- point-like objects with non-trivial scattering behaviour. The construction is developed for…

Unitarity of Quantum Theory and Closed Time-Like Curves
C. J. Fewster, C. G. Wells
Interacting quantum fields on spacetimes containing regions of closed timelike curves (CTCs) are subject to a non-unitary evolution . Recently, a prescription has been proposed,…
