I also discuss how broken symmetries in space and space-time provide the opportunity to induce topological order in metamaterials. Another class of metamaterials based on broken symmetries are parity-time symmetric media, which are asymmetric in space, but symmetric upon parity and time inversion, and can enhance the exotic response of metamaterials beyond the limitations of passive systems. In the talk, I will discuss the impact of these concepts from basic science to technology, from classical waves to quantum phenomena.
