Spatial Kramers-Kronig relation and unidirectional light reflection induced by Rydberg dipole-dipole interactions
Di-Di Zheng, Yan Zhang, Yi-Mou Liu +2
Kramers-Kronig (KK) relation between the dispersion and absorption responses of a signal field can be mapped from the frequency domain into the space domain via the dipole-dipole i…
