Quivers, Lattice Gauge Theories, and Fractons

Physical Review Letters, 2022
We argue that quiver gauge theories with $SU(N)$ gauge groups give rise to lattice gauge theories with matter possessing fractonic properties, where the lattice is the quiver itself. This idea extends a recent proposal by Razamat. This class of theories exhibit a $\mathbb{Z}_N$ 1-form global symmetry that can be used to classify their phases. The order

Dynamics of a lattice 2-group gauge theory model

Journal of High Energy Physics, 2021
We study a simple lattice model with local symmetry, whose construction is based on a crossed module of finite groups. Its dynamical degrees of freedom are associated both to links and faces of a four-dimensional lattice.

Quantum simulation of gauge theory via orbifold lattice

Journal of High Energy Physics, 2021
We propose a new framework for simulating U(k) Yang-Mills theory on a universal quantum computer. This construction uses the orbifold lattice formulation proposed by Kaplan, Katz, and Unsal, who originally applied it to supersymmetric gauge theories. Our

On lattice chiral gauge theories [PDF]

Physics Letters B, 1991
Abstract We consider the Smit-Swift-Aoki formulation of a lattice chiral gauge theory, in which the Wilson and other non-invariant terms in the action are made gauge-invariant by the coupling with a non-linear auxiliary scalar field, Ω. We show that Ω decouples from the physical states only if appropriate parameters are tuned so as to satisfy a set ...

Anomaly inflow, dualities, and quantum simulation of Abelian lattice gauge theories induced by measurements

Physical Review Research
Previous work [SciPost Phys. 14, 129 (2023)2542-465310.21468/SciPostPhys.14.5.129] has demonstrated that quantum simulation of Abelian lattice gauge theories (Wegner models including the toric code in a limit) in general dimensions can be achieved by ...

Fractional Wannier Orbitals and Tight-Binding Gauge Fields in Kitaev Honeycomb Superlattices with Flat Majorana Bands

Physical Review X
Fractional excitations hold immense promise for both fundamental physics and quantum technologies. However, constructing lattice models for their dynamics under gauge fields remains a formidable challenge due to inherent obstructions.

Tensor Networks for Lattice Gauge Theories with Continuous Groups

Physical Review X, 2014
We discuss how to formulate lattice gauge theories in the tensor-network language. In this way, we obtain both a consistent-truncation scheme of the Kogut-Susskind lattice gauge theories and a tensor-network variational ansatz for gauge-invariant states ...

Z_{N} lattice gauge theory in a ladder geometry

Physical Review Research, 2021
Under the perspective of realizing analog quantum simulations of lattice gauge theories, ladder geometries offer an intriguing playground, relevant for ultracold atom experiments. Here, we investigate Hamiltonian lattice gauge theories defined in two-leg

From square plaquettes to triamond lattices for SU(2) gauge theory

Communications Physics
Lattice gauge theory should be able to address significant new scientific questions when implemented on quantum computers. In practice, error-mitigation techniques have already allowed encouraging progress on small lattices.
