Extended Data Fig. 1: Localization at various synthetic electric field strengths.

The dynamics of a particle in an 11-site one-dimensional chain after being initialized at the central site. Dynamics at various synthetic electric field strengths are shown; field strengths are indicated at top in units of the coupling strength J. Experimental data are accompanied by simulations of the actual experiment and of an idealized model with a linear potential. When the synthetic electric field is zero, the particle propagates to the edges of the chain and reflects. As the electric field approaches J per site, Wannier-Stark localization of the particle becomes apparent: the particle does not reach the edges of the chain. At higher electric fields, the localization length decreases and the particle’s dynamics are tightly confined around its initial position.
