Bound state in the continuum and multiple atom state transfer applications in a waveguide QED setup
Xiang Guo, Xiaojun Zhang, Mingzhu Weng +5
Bound states in the continuum (BICs) have been extensively exploited to enhance light--matter interactions in metamaterials, yet their emergence and utility in multi-atom waveguide…
Engineering atomic superradiance scaling in cavity QED system with collective and individual emission channels
Ruijin Sun, Xiang Guo, Andreas Ruschhaupt +1
The coherent emission of multiple atoms gives rise to superradiance, a cornerstone phenomenon in quantum optics with wide-ranging applications in quantum information processing and…
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…
Controllable superradiance scaling in photonic waveguide
Xiang Guo, Zhihai Wang
We investigate the superradiance of two-level target atoms (TAs) coupled to a photonic waveguide, demonstrating that the scaling of the superradiance strength can be controlled on…
