Parquet-like equations for the Hedin three-leg vertex
Friedrich Krien, Angelo Valli
Taking the competition and the mutual screening of various bosonic fluctuations in correlated electron systems into account requires an unbiased approach to the many-body problem.…
Synergy between Hund-driven correlations and boson-mediated Superconductivity
Laura Fanfarillo, Angelo Valli, Massimo Capone
Multiorbital systems such as the iron-based superconductors provide a new avenue to attack the longstanding problem of superconductivity in strongly correlated systems. In this wor…
Single-boson exchange decomposition of the vertex function
Friedrich Krien, Angelo Valli, Massimo Capone
We present a decomposition of the two-particle vertex function of the single-band Anderson impurity model which imparts a physical interpretation of the vertex in terms of the exch…
Quantum interference assisted spin filtering in graphene nanoflakes
Angelo Valli, Adriano Amaricci, Valentina Brosco +1
We demonstrate that hexagonal graphene nanoflakes with zigzag edges display quantum interference (QI) patterns analogous to benzene molecular junctions. In contrast with graphene s…
Inducing and controlling magnetism in the honeycomb lattice through harmonic trapping potential
Karla Baumann, Angelo Valli, Adriano Amaricci +1
We study strongly interacting ultracold spin-1/2 fermions in a honeycomb lattice in the presence of a harmonic trap. Tuning the strength of the harmonic trap we show that it is pos…
