Realization of uniform synthetic magnetic fields by periodically shaking an optical square lattice.

Shaking a lattice system, by modulating the location of its sites periodically in time, is a powerful method to create effective magnetic fields in engineered quantum systems, such as cold gases trapped in optical lattices. However, such schemes are typically associated with space-dependent effectiv...
