Paired Parton Trial States for the Superfluid-Fractional Chern Insulator Transition

Author(s): Tevž Lotrič and Steven H. Simon We consider a model of hard-core bosons on a lattice half-filling a Chern band such that the system has a continuous transition between a fractional Chern insulator (FCI) and a superfluid state (SF) depending on the bandwidth to bandspacing ratio. We construct a parton-inspired trial wave function A… [Phys. Rev. Lett. 136, 096601] Published Tue Mar 03, 2026
