Fractionalized holes in one-dimensional ${\mathbb{Z}}_2$ gauge theory coupled to fermion matter -- deconfined dynamics and emergent integrability

Aritra Das, Umberto Borla, Sergej Moroz

We investigate the interplay of quantum one-dimensional discrete ${\mathbb{Z}}_2$ gauge fields and fermion matter near full filling in terms of deconfined fractionalized hole excitat…
