Multipartite entanglement and quantum criticality of Rydberg atoms trapped in a two-dimensional optical lattice

We investigate the multipartite entanglement and quantum criticality of neutral atoms on a two-dimensional square lattice, interacting via laser excitation to atom Rydberg states. It is found that the first derivative of residual entanglement with respect to detuning has peaks near the critical poin...
