Quantum simulation of lattice gauge theories
Lattice gauge theories are central to our understanding of the standard model of particle physics and also capture emergent phenomena in strongly correlated systems, such as quantum spin liquids. Realizing these theories controllably in a quantum simulator would allow us to overcome key limitations of classical simulations. In our work, we have proposed implementations of lattice gauge theories on platforms including cold atoms in optical lattices and Rydberg atom arrays, and explored their rich and exotic dynamical behaviors.
