DOI: 10.1007/s10701-019-00313-8
Abstract: Spin is a fundamental and distinctive property of the electron, having far-reaching implications. Yet its purely formal treatment often blurs the physical content and meaning of the spin operator and associated observables. In this work… read more here.

DOI: 10.1007/s10955-018-2121-y
Abstract: In this paper, we study the truncated two-particle correlation function in particle systems with long range interactions. For Coulombian and soft potentials, we define and give well-posedness results for the equilibrium correlations. In the Coulombian… read more here.
