Simulating Correlated Electrons with Symmetry-Enforced Normalizing Flows
Dominic Schuh, Janik Kreit, Evan Berkowitz +4
We present the first proof of principle that normalizing flows can accurately learn the Boltzmann distribution of the fermionic Hubbard model - a key framework for describing the e…
Fully ergodic simulations using radial updates
Finn L. Temmen, Evan Berkowitz, Anthony Kennedy +3
A sensible application of the Hybrid Monte Carlo (HMC) method is often hindered by the presence of large - or even infinite - potential barriers. These potential barriers separate…
Search for Stable States in Two-Body Excitations of the Hubbard Model on the Honeycomb Lattice
Petar Sinilkov, Evan Berkowitz, Thomas Luu +1
We present one- and two-body measurements for the Hubbard model on the honeycomb (graphene) lattice from ab-initio quantum monte carlo simulations. Of particular interest is excito…
Simulating the Hubbard Model with Equivariant Normalizing Flows
Dominic Schuh, Janik Kreit, Evan Berkowitz +4
Generative models, particularly normalizing flows, have shown exceptional performance in learning probability distributions across various domains of physics, including statistical…
Overcoming Ergodicity Problems of the Hybrid Monte Carlo Method using Radial Updates
Finn Temmen, Evan Berkowitz, Anthony Kennedy +3
Despite its many advantages, the sensible application of the Hybrid Monte Carlo (HMC) method is often hindered by the presence of large - or even infinite - potential barriers. The…
Reducing the Sign Problem with simple Contour Deformation
Christoph Gäntgen, Evan Berkowitz, Thomas Luu +2
We apply constant imaginary offsets to the path integral for a reduction of the sign problem in the Hubbard model. These simple transformations enhance the quality of results from…
Single Particle Spectrum of Doped -Perylene
Marcel Rodekamp, Evan Berkowitz, Christoph Gäntgen +4
We present a Hamiltonian Monte Carlo study of doped perylene described with the Hubbard model. Doped perylene can be used for organic light-emittin…
