Description
While real-time simulation of Quantum Chromodynamics remains technologically out of reach, simplified models for studying elements of QCD phenomenology abound. This work aims to add a spin-1 truncation of 1+1D scalar electrodynamics represented on a chain of qutrit sites to the collection of models considered to demonstrate confinement and string breaking accessible to current simulation methods. We study the spectrum of the effective string model using DMRG methods on the order of 100 sites. We demonstrate that an added chemical potential, playing a role analogous to external charges, permits parameter-dependent measurements of physical features of interest like the string tension and effective meson mass. Varying the chemical potential also permits a characterization of string stability not assessed in prior studies of confining lattice models.
