Variational Minimization of Orbital-dependent Density Functionals
Cheol-Hwan Park, Andrea Ferretti, Ismaila Dabo +2
Functionals that strive to correct for such self-interaction errors, such as those obtained by imposing the Perdew-Zunger self-interaction correction or the generalized Koopmans' c…
On a conjecture of Oguiso about rational curves on Calabi-Yau threefolds
Simone Diverio, Andrea Ferretti
Let X be a Calabi-Yau threefold. We show that if there exists on X a non-zero nef non-ample divisor then X contains a rational curve, provided its second Betti number is greater th…
Transport properties of molecular junctions from many-body perturbation theory
T. Rangel, A. Ferretti, P. E. Trevisanutto +2
The conductance of single molecule junctions is calculated using a Landauer approach combined to many-body perturbation theory MBPT) to account for electron correlation. The mere c…
