Bound state in the continuum and dynamics via phase modulation in giant-atom waveguide setups
Ji Qi, Xiaojun Zhang, Honngwei Yu +1
Giant atoms, which couple to a waveguide through multiple spatially separated connection points beyond the dipole approximation, provide a versatile route for quantum information p…

Giant emitter magnetometer
Xiaojun Zhang, Xiang Guo, Zhihai Wang
Leveraging the sensitive dependence of a giant atom's radiation rate on its frequency [A. F. Kockum, ., Phys. Rev. A 90, 013837 (2014)], we propose an effective magnetometer…

Rabi oscillation and fractional population via the bound states in the continuum in a giant atom waveguide QED setup
Hongwei Yu, Xiaojun Zhang, Zhihai Wang +1
We study the dynamics of two giant atoms interacting with a coupled resonator waveguide (CRW) beyond the Markovian approximation. The distinct atomic configurations determine the n…
