Theory of Subradiant States of a One-Dimensional Two-Level Atom Chain
Yu-Xiang Zhang, Klaus Mølmer
Recently, the subradiant states of one-dimensional two-level atom chains coupled to light modes were found to have decay rates obeying a universal scaling, and an unexpected fermio…
Surface plasmon launching by polariton superradiance
Yu-Xiang Zhang, Yuan Zhang, Klaus Mølmer
The condition of phase matching prohibits the transfer of excitation from free-space photons to surface plasmon polaritons (SPP). We propose and analyze a scheme that excites an en…
Monte-Carlo Simulations of Superradiant Lasing
Yuan Zhang, Yu-Xiang Zhang, Klaus Mølmer
We present simulations of the superradiant dynamics of ensembles of atoms in the presence of collective and individual atomic decay processes. We unravel the density matrix with Mo…
Dicke Phase Transition in a Disordered Emitter-Graphene Plasmon System
Yu-Xiang Zhang, Yuan Zhang, Klaus Mølmer
We study the Dicke phase transition in a disordered system of emitters coupled to the plasmonic modes of a graphene monolayer. This system has unique properties associated with the…
