Variational formulation of dynamical electronic response functions in presence of nonlocal exchange interactions
Giovanni Caldarelli, Alberto Guandalini, Francesco Macheda +1
We consider the dynamical electronic response function in theoretical frameworks that include nonlocal exchange interactions, such as the Bethe-Salpeter equation with the frequency…
Lattice thermal conductivity in the anharmonic overdamped regime
Đorđe Dangić, Giovanni Caldarelli, Raffaello Bianco +2
In crystalline materials, low lattice thermal conductivity is often associated with strong anharmonicity, which can cause significant deviations from the expected Lorentzian linesh…
High- and low-energy many-body effects of graphene in a unified approach
Alberto Guandalini, Giovanni Caldarelli, Francesco Macheda +1
We show that the many-body features of graphene band structure and electronic response can be accurately evaluated by applying many-body perturbation theory to a tight-binding (TB)…
