Revisiting the Equation-of-Motion Method: A Universal Framework for Correlated Quantum Systems
Andrea Porro
A general implementation of the equation-of-motion (EOM) formalism for correlated many-body states is presented and applied to the description of collective excitations in atomic n…
Nuclear giant resonances from first principles
Sonia Bacca, Francesco Marino, Andrea Porro
This chapter presents an ab initio perspective on giant resonances in atomic nuclei and surveys the principal theoretical frameworks that aim to describe these collective excitatio…
Ab initio calculations of monopole sum rules: From finite nuclei to infinite nuclear matter
Francesca Bonaiti, Andrea Porro, Sonia Bacca +2
We compute moments of the isoscalar monopole response of N = Z closed-shell nuclei based on chiral nucleon-nucleon plus three-nucleon interactions. We employ the random phase appro…
Impact of ground-state correlations on the multipole response of nuclei: Ab initio calculations of moment operators
Andrea Porro, Achim Schwenk, Alexander Tichai
We develop a framework that allows to calculate integrated properties of the nuclear response from first principles. Using the ab initio in-medium similarity renormalization group…
