Photonic Bound States and Scattering Resonances in Waveguide QED
Bastian Bakkensen, Yu-Xiang Zhang, Johannes Bjerlin +1
We study the emergence of two types of two-photon bounds states in waveguides of any chirality. Specifically, we present a systematic way of analytically determining the eigenstate…
Subradiant emission from regular atomic arrays: universal scaling of decay rates from the generalized Bloch theorem
Yu-Xiang Zhang, Klaus Mølmer
The Hermitian part of the dipole-dipole interaction in infinite periodic arrays of two-level atoms yields an energy band of singly excited states. In this Letter, we show that a di…
Magnon Accumulation in Chirally Coupled Magnets
Tao Yu, Yu-Xiang Zhang, Sanchar Sharma +2
We report strong chiral coupling between magnons and photons in microwave waveguides that contain chains of small magnets on special lines. Large magnon accumulations at one edge o…
Subradiant Dimer Excitations of Emitter Chains Coupled to a 1D Waveguide
Yu-Xiang Zhang, Chuan Yu, Klaus Mølmer
This Letter shows that chains of optical or microwave emitters coupled to a 1D waveguide support subradiant states with close pairs of excited emitters, which have longer lifetimes…
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…
