Accuracy of Restricted Boltzmann Machines for the one-dimensional Heisenberg model
Luciano Loris Viteritti, Francesco Ferrari, Federico Becca
Neural networks have been recently proposed as variational wave functions for quantum many-body systems [G. Carleo and M. Troyer, Science 355, 602 (2017)]. In this work, we focus o…
Gutzwiller-projected states for the - Heisenberg model on the kagome lattice: achievements and pitfalls
Yasir Iqbal, Francesco Ferrari, Aishwarya Chauhan +3
We assess the ground-state phase diagram of the - Heisenberg model on the kagome lattice by employing Gutzwiller-projected fermionic wave functions. Within this framework…
Effects of spin-phonon coupling in frustrated Heisenberg models
Francesco Ferrari, Roser Valenti, Federico Becca
The existence and stability of spin-liquid phases represent a central topic in the field of frustrated magnetism. While a few examples of spin-liquid ground states are well establi…
Gapless spin liquids in disguise
Francesco Ferrari, Alberto Parola, Federico Becca
We show that gapless spin liquids, which are potential candidates to describe the ground state of frustrated Heisenberg models in two dimensions, become trivial insulators on cylin…
Variational wave functions for the spin-Peierls transition in the Su-Schrieffer-Heeger model with quantum phonons
Francesco Ferrari, Roser Valenti, Federico Becca
We introduce variational wave functions to evaluate the ground-state properties of spin-phonon coupled systems described by the Su-Schrieffer-Heeger model. Quantum spins and phonon…
Gapless spin liquid and valence-bond solid in the Heisenberg model on the square lattice: insights from singlet and triplet excitations
Francesco Ferrari, Federico Becca
The spin- Heisenberg model on the square lattice represents one of the simplest examples in which the effets of magnetic interactions may suppress magnetic order, ev…
