The many-body problem is ubiquitous in the theoretical description of physical phenomena, ranging from the behaviour of elementary particles to the physics of electrons in solids. Most of our understanding of many-body systems comes from analysing the symmetric properties of Hamiltonian and states: the most striking examples are gauge theories such as quantum electrodynamics, where a local symmetry strongly constrains the microscopic dynamics. The physics of such gauge theories is relevant for…

Observation of gauge invariance in a 71-site Bose-Hubbard quantum simulator.
The quantum simulation of an extended U(1) lattice gauge theory is reported, and the degree to which Gauss's law is violated is measured by extracting probabilities of locally gauge-invariant states from correlated atom occupations, providing a way to explore gauge symmetry in the interplay of fundamental particles using controllable large-scale quantum simulators.
