Realizing strongly correlated topological phases of ultracold gases is a central goal for ongoing experiments. While fractional quantum Hall states could soon be implemented in small atomic ensembles, detecting their signatures in few-particle settings remains a fundamental challenge. In this work, we numerically analyze the center-of-mass Hall drift of a small ensemble of hardcore bosons, initially prepared in the ground state of the Harper-Hofstadter-Hubbard model in a box potential.

Many-Body Chern Number from Statistical Correlations of Randomized Measurements.
This work uses the statistical correlations of randomized measurements to infer the many-body Chern number of a wave function, and its results apply to disklike geometries that are more amenable to current quantum simulator architectures. Expand
Bosonic Pfaffian state in the Hofstadter-Bose-Hubbard model

Charge Excitation Dynamics in Bosonic Fractional Chern Insulators.
This model contrasts the behavior of single particle models with counterpropagating edge states, such as the noninteracting Harper-Hofstadter model, where the chirality is manifest only for weak perturbations. Expand
Detecting Fractional Chern Insulators in Optical Lattices through Quantized Displacement.
It is shown that for a ν=1/2 FCI state realized in the lowest band of a Harper-Hofstadter model of interacting bosons confined by a harmonic trapping potential, the fractionally quantized Hall conductivity σ_{xy} can be accurately determined by the displacement of the atomic cloud under the action of a constant force which provides a suitable experimentally measurable signal for detecting the topological nature of the state.

Interferometric measurements of many-body topological invariants using mobile impurities
