Quantum spin systems can exhibit novel quantum phases that do not have any classical analog and thus cannot be understood using conventional field theories. The same reason that makes these phases fascinating, makes them experimentally hard to detect: they lack symmetry breaking and are characterized by their non-local entanglement. In this project, we plan to use a combination of analytically tractable models, novel numerical methods as well as machine learning tools to obtain and characterize dynamical response functions for a range of experimentally relevant quantum spin systems.
