Abstract: It is known that, in the thermodynamic limit, the Chern number of a translationally invariant system cannot change under unitary time evolutions that are smooth in momentum space. Yet a real-space counterpart of the Chern… read more here.

DOI: 10.1103/physrevc.104.024612
Abstract: This paper concerns the theory of direct A(d, p)B reactions and how practical 3-body models of them are related to the optical model potentials describing the interaction of the deuterons constituents and the target A.… read more here.

DOI: 10.1103/physrevc.97.034619
Abstract: Background: The nuclear optical potential is a successful tool for the study of nucleon-nucleus elastic scattering and its use has been further extended to inelastic scattering and other nuclear reactions. The nuclear density of the… read more here.

DOI: 10.1103/physrevc.99.044608
Abstract: Earlier work showed how a nucleon optical model wave function could be defined as a projection of a many-nucleon scattering state within a translationally invariant second quantised many-body theory. In this paper an optical potential… read more here.
