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…

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…

Entropy Engineered Middle-In Synthesis of Dual Single-Atom Compounds for Nitrate Reduction Reaction
Yao Hu, Haihui Lan, Junjun He +5
Despite the immense potential of Dual Single-Atom Compounds (DSACs), the challenges in their synthesis process, including complexity, stability, purity, and scalability, remain pri…
