The one-dimensional lattice Schwinger model has recently been realized by using bosons in optical lattices. This contains both confinement and deconfinement phases, whose phase diagram is controlled the mass of matter field topological angle. Since varying straightforward experimentally, we propose how to tune angle, allowing accessing entire diagram. We that direct experimental evidence can be obtained measuring whether a physical charge localized around fixed gauge screen it. also discuss PXP Rydberg atoms array, which equivalent when all local charges are as zero. Although fixed, alternatively probe studying relative motion pair an anti-charge. Our scheme directly implemented these two relevant platforms ultracold atom quantum simulators.
