We pursued the project Engineering Exotic Topological Matter and Complex Entanglement Patterns in Atomic, Molecular, and Optical Systems along several directions. The project was very successful resulting in numerous publications. For example, we proposed ways to generate exotic topological states with photons, dipoles, ultracold bosonic atoms, and spinsqubits. We have also studied the effects of long-range interactions on topological phases, on continuous symmetry breaking, on causality and quantum criticality, on the rate of entanglement generation, on the amount of entanglement in ground states, on thermalization rates, and on dynamical phase transitions. One particularly relevant example is a protocol for using long-range interactions to quickly create states specified by a MERA multiscale entanglement renormalization ansatz. Such MERA circuits are among the most promising approaches for quickly preparing topological states in AMO systems. Another particularly relevant example is a protocol for efficiently preparing integer quantum Hall states with alkaline-earth atoms.
