Transformer-based operator learning framework for self-energy in strongly correlated systems
Yuanran Zhu, Peter Rosenberg, Zhen Huang +3
We introduce -Attention, a Transformer-based operator-learning framework to address a key computational challenge in correlated materials. Our approach utilizes an Encoder-Only…
Monte Carlo Methods in the Manifold of Hartree-Fock-Bogoliubov Wave Functions
Ettore Vitali, Peter Rosenberg, Shiwei Zhang
We explore the possibility to implement random walks in the manifold of Hartree-Fock-Bogoliubov wave functions. The goal is to extend state-of-the-art quantum Monte Carlo approache…
Dynamical Variational Monte Carlo as a quantum impurity solver: Application to Cluster Dynamical Mean-Field Theory
P. Rosenberg, D. Sénéchal, A. -M. S. Tremblay +1
Two of the primary sources of error in the Cluster dynamical mean-field theory (CDMFT) technique arise from the use of finite size clusters and finite size baths, which makes the d…
Fermi Arcs From Dynamical Variational Monte Carlo
P. Rosenberg, D. Sénéchal, A. -M. S. Tremblay +1
Variational Monte Carlo is a many-body numerical method that scales well with system size. It has been extended to study the Green function only recently by Charlebois and Imada (2…
Topological Superconductivity in a two-dimensional Weyl SSH model
Peter Rosenberg, Efstratios Manousakis
We study the emergence of topological superconductivity in a two-dimensional (2D) Weyl system, composed of stacked Su-Schrieffer-Heeger (SSH) chains. A previous analysis of the mod…
Weyl Nodal-Ring Semimetallic Behavior and Topological Superconductivity in Crystalline Forms of Su-Schrieffer-Heeger Chains
Peter Rosenberg, Efstratios Manousakis
We consider a three-dimensional model of coupled Su-Schrieffer-Heeger (SSH) chains. The analytically soluble model discussed here reliably reproduces the features of the band struc…
