Resonator-assisted single-photon frequency convertion in a conventional waveguide with a giant V-type atom
Ge Sun, Hongzheng Wu, Jing Lu +1
We propose a scheme to achieve efficient frequency conversion for a single photon propagating in a 1D conventional waveguide by exploiting the quantum interference induced by the s…

Tunable single-photon frequency converter in a waveguide with a giant V-type atom
Hongzheng Wu, Ge Sun, Jing Lu +1
We study the single-photon scattering in a one-dimensional (1D) waveguide coupled to one transition of a -type giant atom (GA), whose other transition is coherently driven by an…

Bound states and the collective dynamics of Distant Quantum Emitters coupled to a chiral waveguide
Meng Qian Wu, Ge Sun, Jing Lu +1
We consider two two-level quantum emitters (QEs) with separations on the order of the wavelength which are chirally coupled to a one-dimensional (1D) waveguide, and the electromagn…
