Plasmon assisted superconductivity in LiTiO
Francesco Petocchi, Viktor Christiansson, Ryotaro Arita +1
We combine plus extended dynamical mean field theory (+EDMFT) with the density functional theory for superconductors (SCDFT) framework to study the electronic properties o…

The long-range origin of the black hole entropy
Andrea Solfanelli, Francesco Petocchi, Nicolò Defenu
The Sachdev-Ye-Kitaev (SYK) model, has emerged as a powerful tool for exploring the quantum nature of black holes, particularly their residual entropy at zero temperature. In this…

Fermion quartets on the square lattice
Dionys Baeriswyl, Francesco Petocchi, Philipp Werner
We study a microscopic model for four spinless fermions on the square lattice which exhibits a quartet bound state in the strong coupling regime. The four-particle quantum states a…
