Nematic confined phases in the U(1) quantum link model on a triangular lattice: near-term quantum computations of string dynamics on a chip
The U⁡(1) quantum link model on the triangular lattice has two rotation-symmetry-breaking nematic confined phases. Static external charges are connected by confining strings consisting of individual strands with fractionalized electric flux. The two phases are separated by a weak first-order phase transition with an emergent, almost exact SO⁡(2) symmetry. We construct a quantum circuit on a chip to facilitate near-term quantum computations of the nontrivial string dynamics.

Abstract

The U⁡(1) quantum link model on the triangular lattice has two rotation-symmetry-breaking nematic confined phases. Static external charges are connected by confining strings consisting of individual strands with fractionalized electric flux. The two phases are separated by a weak first-order phase transition with an emergent, almost exact SO⁡(2) symmetry. We construct a quantum circuit on a chip to facilitate near-term quantum computations of the nontrivial string dynamics.
