Accelerating Quantum Monte Carlo Calculations with Set-Equivariant Architectures and Transfer Learning
Manuel Gallego, Sebastián Roca-Jerat, David Zueco +1
Machine-learning (ML) ansätze have greatly expanded the accuracy and reach of variational quantum Monte Carlo (QMC) calculations, in particular when exploring the manifold quantum…

First- and second-order quantum phase transitions in the long-range unfrustrated antiferromagnetic Ising chain
VÃctor Herráiz-López, Sebastián Roca-Jerat, Manuel Gallego +4
We study the ground-state phase diagram of an unfrustrated antiferromagnetic Ising chain with longitudinal and transverse fields in the full range of interactions: from all-to-all…

Transformer Wave Function for Quantum Long-Range models
Sebastián Roca-Jerat, Manuel Gallego, Fernando Luis +2
We employ a neural-network architecture based on the Vision Transformer (ViT) architecture to find the ground states of quantum long-range models, specifically the transverse-field…
