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…
