Beating the Bad-Cavity Limit via Auxiliary-Emitter Linewidth Squeezing
Youke Xu, Zeyang Liao, Xue-hua Wang
The paper proposes adding two detuned auxiliary emitters to a low‑Q cavity to create a subradiant mode that narrows the effective cavity linewidth, enabling strong‑coupling phenome…
Theory of the Collective Many-body Subradiance in Waveguide Quantum Electrodynamics
Xin Wang, Junjun He, Zeyang Liao
We present an analytical theory for the most subradiant modes in a finite one-dimensional emitter array coupled to either an ideal or a nonideal waveguide. Using an effective non-H…
Super-Heisenberg-limited Sensing via Collective Subradiance in Waveguide Quantum Electrodynamics
Xin Wang, Zeyang Liao
We explore the quantum-metrological potential of subwavelength-spaced emitter arrays coupled to a one-dimensional nanophotonic waveguide. In this system, strong dipole--dipole inte…
Tunable ultrahigh reflection with broadband via collective atom-atom interaction in waveguide-QED system
Xin Wang, Junjun He, Zeyang Liao +1
We present a scheme for achieving broadband complete reflection by constructing photonic bandgap via collective atom-atom interaction in a one-dimensional (1D) waveguide quantum el…
