Photons and polaritons in a broken-time-reversal nonplanar resonator
Photons and polaritons in a broken-time-reversal nonplanar resonator
The combination of twisted resonators with Rydberg polaritons is experimentally explored to simultaneously break inversion and time-reversal symmetries. Besides showing how to design a low-loss optical isolator, the work provides tools for the exploration of topological many-body physics from light.
