Overcoming exponential volume scaling in quantum simulations of lattice gauge theories
Christopher F. Kane, Dorota M. Grabowska, Benjamin Nachman +1
Real-time evolution of quantum field theories using classical computers requires resources that scale exponentially with the number of lattice sites. Because of a fundamentally dif…
Analytic expansions of two- and three-particle excited-state energies
Dorota M. Grabowska, Maxwell T. Hansen
The last years have seen significant developments in methods relating two- and three-particle finite-volume energies to scattering observables. These relations hold for both weakly…
A Chiral Solution to the Ginsparg-Wilson Equation
Dorota M. Grabowska, David B. Kaplan
We present a chiral solution of the Ginsparg-Wilson equation. This work is motivated by our recent proposal for nonperturbatively regulating chiral gauge theories, where five-dimen…
Nonperturbative Regulator for Chiral Gauge Theories?
Dorota M. Grabowska, David B. Kaplan
We propose a nonperturbative gauge invariant regulator for d-dimensional chiral gauge theories on the lattice. The method involves simulating domain wall fermions in d + 1 dimensio…
Elucidating the sign problem through noise distributions
Amy N. Nicholson, Dorota Grabowska, David B. Kaplan
Due to the presence of light pions in the theory, lattice QCD at finite densities suffers from issues with noise in both grand canonical and canonical formulations. We study two di…
Sign problems, noise, and chiral symmetry breaking in a QCD-like theory
Dorota Grabowska, David B. Kaplan, Amy N. Nicholson
The Nambu-Jona-Lasinio model reduced to 2+1 dimensions has two different path integral formulations: at finite chemical potential one formulation has a severe sign problem similar…
