Third moments of nucleon unpolarized, polarized, and transversity parton distribution functions from physical-point lattice QCD
Emilio Taggi, Michael Engelhardt, Jeremy R. Green +6
Using forward matrix elements of local leading-twist operators, we present a determination of the isovector third Mellin moments of nucleon unpolarized, polari…
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…
Exploring Group Convolutional Networks for Sign Problem Mitigation via Contour Deformation
Christoph Gäntgen, Thomas Luu, Marcel Rodekamp
The sign problem that arises in Hybrid Monte Carlo calculations can be mitigated by deforming the integration manifold. While simple transformations are highly efficient for simula…
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…
