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…
Quark orbital angular momentum in the proton from a twist-3 generalized parton distribution
M. Engelhardt, N. Hasan, S. Krieg +6
Quark orbital angular momentum in the proton is evaluated via a Lattice QCD calculation of the second Mellin moment of the twist-3 generalized parton distribution $\widetilde{E}_{2…
Moments of Nucleon Unpolarized, Polarized, and Transversity Parton Distribution Functions from Lattice QCD at the Physical Point
Marcel Rodekamp, Michael Engelhardt, Jeremy R. Green +6
The second Mellin moments of the nucleon's unpolarized, polarized, and transversity parton distribution functions (PDFs) are computed. Two lattice QCD ensembles…
