Resonating valence bond wave function with molecular orbitals: Application to first-row molecules
M. Marchi, S. Azadi, M. Casula +1
We introduce a method for accurate quantum chemical calculations based on a simple variational wave function, defined by a single geminal that couples all the electrons into single…
A consistent description of the iron dimer spectrum with a correlated single-determinant wave function
Michele Casula, Mariapia Marchi, Sam Azadi +1
We study the iron dimer by using an accurate ansatz for quantum chemical calculations based on a simple variational wave function, defined by a single geminal expanded in molecular…
Variational wave functions for frustrated magnetic models
Federico Becca, Luca Capriotti, Alberto Parola +1
Variational wave functions containing electronic pairing and suppressed charge fluctuations (i.e., projected BCS states) have been proposed as the paradigm for disordered magnetic…
From magnetism to one-dimensional spin liquid in the anisotropic triangular lattice
Dariush Heidarian, Federico Becca, Sandro Sorella
We investigate the anisotropic triangular lattice that interpolates from decoupled one-dimensional chains to the isotropic triangular lattice and has been suggested to be relevant…
