Abstract
AbstractWe study the interaction of a single photon in a surface plasmon polariton mode with multiple atoms. We propose a system of two atoms to achieve a tunable scattering from subscattering to superscattering regimes by changing the angle of the incident photon. We also demonstrate a perfect electromagnetically-induced transparency using two atoms with two-level structures. The proposed framework is efficiently scalable to a system with a large number of atoms and opens up the possibility of designing novel atom-based optical devices. We design an atomically thin parabolic mirror to focus single photons and form a quantum mirage in a cavity built from atoms.

We presented a general model for the scattering of surface plasmon polariton (SPP) mode by a single atom without making the usual dipole approximation [15]
Summary
Photon–atom interaction is an important subject with considerable theoretical and practical interests [1,2,3]. In recent years there have been numerous studies investigating the coherent scattering of a few photon Fock states by an atom [7,8,9,10,11,12,13,14,15,16] Most of these studies, are concerned with a single or a few atoms coupled to one. We achieve a perfect atom cloaking with zero scattering at a certain frequency between the resonant frequency of the two atoms This is different from the usual electromagnetically-induced transparency (EIT) which is based on interference between the transition paths in an atom with at least a three-level structure [1, 19,20,21]. We further explore the possibilities of designing novel atom-based optical devices to manipulate single photons and demonstrate multiple atoms based single photon focusing and the formation of quantum mirage in a 2D cavity like system
