Resonating Valence Bond wave function: from lattice models to realistic systems
Michele Casula, Seiji Yunoki, Claudio Attaccalite +1
Although mean field theories have been very successful to predict a wide range of properties for solids, the discovery of high temperature superconductivity in cuprates supported t…
Correlated geminal wave function for molecules: an efficient resonating valence bond approach
M. Casula, C. Attaccalite, S. Sorella
We show that a simple correlated wave function, obtained by applying a Jastrow correlation term to an Antisymmetrized Geminal Power (AGP), based upon singlet pairs between electron…
d-wave pairing in lightly doped Mott insulators
Evgeny Plekhanov, Federico Becca, Sandro Sorella
We define a suitable quantity that measures the pairing strength of two electrons added to the ground state wave function by means of the anomalous part of the one-particle G…
Variational description of Mott insulators
Manuela Capello, Federico Becca, Michele Fabrizio +2
The Gutzwiller wave function for a strongly correlated model can, if supplemented with a long-range Jastrow factor, provide a proper variational description of Mott insulators, so…
