The Correlation Energy of the Electron Gas in the Mean-Field Regime
Martin Ravn Christiansen, Christian Hainzl, Phan Thà nh Nam
We prove a rigorous lower bound on the correlation energy of interacting fermions in the mean-field regime for a wide class of singular interactions, including the Coulomb potentia…

A Correlational Bound for Eigenvalues of Fermionic 2-Body Operators
Martin Ravn Christiansen
We prove that the eigenvalues of a 2-body operator $γ_{2}^Ψ$ associated to a fermionic -particle state are highly constrained by the structure of the corresponding eigenv…

Probing small neutron skin variations in isotope pairs by hyperon-antihyperon production in antiproton--nucleus interactions
Falk Schupp, Josef Pochodzalla, Michael Bölting +4
We propose a new method to study the evolution of the neutron periphery between different isotopes by considering antiproton--nucleus interactions close to the production threshold…
