Abstract

We demonstrate characteristics of a bosonic fractional quantum H all (FQH) state in a one- dimensional extended Bose-Hubbard model (eBHM) with a stati c tilt. In the large tilt limit, quenched kinetic energy leads to emergent dipole moment conse rvation, enabling mapping to a model generating FQH st...

Highlights

-Demonstrates FQH correlations in a 1D tilted eBHM.

-Shows overlap between the ground states of the dipole-conserving model and a 2D FQH Laughlin-like parent model; entanglement signatures consistent with FQH physics.
