## Contribution

It introduces an experimentally feasible model for the Haldane phase with bosons and details how to detect its non-local order and topological features.

## Key findings

- Haldane phase can be realized with bosons in optical lattices
- Quantum gas microscopy can detect non-local string order and edge states
- Supersolid correlations are possible but challenging to observe experimentally

## Abstract

We analyze an experimentally realizable model of bosons in a zig-zag optical lattice, showing that by rapidly modulating the magnetic field one can tune interaction parameters and realize an analog of the Haldane phase. We explain how quantum gas microscopy can be used to detect this phase's non-local string order and its topological edge states. We model the detection process. We also find that this model can display supersolid correlations, but argue that they only occur at parameter values which would be challenging to realize in an experiment.
