Topological order in higher composites
arXiv:2401.02551 · doi:10.1103/PhysRevResearch.6.L032034
Abstract
We introduce the concept of composite topological order in multicomponent systems. In such a state topological order appears only in higher-than-usual composites, with no topological order in elementary fields. We propose that such a state can be realized in Bose-Fermi mixtures in ultracold atoms.
