Controlling radiative dynamics of a giant -type atom via interference induced by the vacuum of a waveguide
Ci-Ming Deng, Ge Sun, Jing Lu +1
We investigate the dynamics of a -type giant atom (GA) whose both transition coupled to the guided modes of a one-dimensional (1D) waveguide at two spatially separated points w…
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…
Cavity Modified Oscillating Bound States with a -type giant emitter in a linear waveguide
Ge Sun, Ya Yang, Jing Li +2
We study a system composed by a three-level giant atom (3GA), a waveguide initially in the vacuum state, and a single-mode cavity. The 3GA-cavity system is in a strong-coupling reg…
Emergent Oscillating bound states in a semi-infinite linear waveguide with a point-like -type quantum emitter driven by a classical field
YuPing He, Ge Sun, Jing Li +3
An oscillating bound state is a phenomenon where excitations mediated by the continuum modes oscillate persistently. Although it is generated by the superposition of two bound stat…
