Quantum simulation of the Schwinger model: A study of feasibility
TL;DR: A feasibility study of quantum simulation of lattice gauge models is performed in this paper, showing rapid convergence with increasing number of dimensions of the chosen representation, robustness to noise, and the possibility of adiabatic preparation of the ground state.

Efficient Basis Formulation for (1+1)-Dimensional SU(2) Lattice Gauge Theory: Spectral calculations with matrix product states
TL;DR: In this article, an explicit formulation of the physical subspace for a (1+1)-dimensional SU(2) lattice gauge theory is proposed, where the gauge degrees of freedom are integrated out.

Non-Abelian string breaking phenomena with Matrix Product States
TL;DR: In this paper, the authors explore the phenomenology of string breaking in a non-Abelian lattice gauge theory, namely 1+1 dimensional SU(2), using matrix product states.
Variational study of U(1) and SU(2) lattice gauge theories with Gaussian states in 1 + 1 dimensions
TL;DR: A method is introduced to investigate the static and dynamic properties of both Abelian and non-Abelian lattice gauge models in $1+1$ dimensions by identifying a set of transformations that disentangle different degrees of freedom, and applying a simple Gaussian variational ansatz to the resulting Hamiltonian.
