Charged particles in a two-dimensional lattice behave like a Chern topological insulator when subject to a perpendicular magnetic field. Here, the authors propose a realistic scheme to use neutral atoms in optical lattices to simulate the effect of the magnetic field and to study transport in the strong field regime, which is not accessible when working with conventional materials. Importantly, the topological behavior of these so-called magnetic quantum walks extends even beyond the Chern insulator model because they are periodically driven in time,. Magnetic quantum walks may open a new route to studying topological properties of charged particles in strong magnetic fields.
