Strong coupling and non-reciprocity in the dynamics of a V-atom placed near an anisotropic metasurface

摘要

In this work we focus on studying the temporal dynamics of a V-type quantum emitter with two excited states, which allows to observe an interplay between different spontaneous emission channels. We show that the presence of an anisotropic metasurface enables an interaction between the two active transitions and makes it possible to achieve a strong coupling regime. We also show that if the rotation plane of the transition dipole moments is arbitrarily oriented with respect to the metasurface interface, it is possible to observe a non-reciprocal behavior.
