Scaling and Luescher Term in a non-Abelian (2+1)d SU Quantum Link Model
Paul Ludwig, Timo Jakobs, Carsten Urbach
We investigate a non-Abelian SU quantum link model in dimensions on a hexagonal lattice using tensor network methods. We determine the static quark potential for a wide…

A Finite-Volume Scheme for the Continuum Extrapolation of Lattice Step-Scaling in (2+1)D Hamiltonian U(1) Gauge Theory
Alessio Negro, Emil Otis Rosanowski, Lena Funcke +4
We propose a finite-volume scheme to perform controlled continuum extrapolations of the lattice step-scaling function, a key ingredient for determining the running coupling in a Ha…

Dynamics in Hamiltonian Lattice Gauge Theory: Approaching the Continuum Limit with Partitionings of SU
Timo Jakobs, Marco Garofalo, Tobias Hartung +4
In this paper, we investigate a digitised SU lattice gauge theory in the Hamiltonian formalism. We use partitionings to digitise the gauge degrees of freedom and show how to d…
