Generalized Model Fractional Quantum Hall States on Lattices

Abstract

Model wave functions are essential for studying fractional quantum Hall phases, yet lattice model states have so far been limited to bosonic systems with on-site interactions. In this work, by combining analytical and numerical methods, we systematically construct lattice model states for the Laughlin, Moore--Read, and general $\mathbb{Z}_k$ Read--Rezayi series. Our lattice-specific states are characterized by their idealized energy and entanglement features and are distinguished from their continuum counterparts by a modified clustering behavior. Our theory advances the understanding of the stability of topologically ordered phases and illustrates the organizing principles of the conformal Hilbert space on lattices. Practically, this work paves the way for further studying lattice-specific excitations and offers a constructive route for engineering topological orders within density interactions, with potential immediate implications for cold-atom and synthetic flat-band platforms.
