Enhancement of signal-to-noise ratio at a high-order exceptional point of coherent perfect absorption
Zi-Qi Wang, Yi-Ming Sun, Yao-Dong Hu +4
Exceptional points (EPs) in non-Hermitian systems offer a remarkably strong response to weak perturbations, but the nonorthogonal nature of the corresponding eigenvectors causes no…
Unidirectional exceptional point of reflectionless states in a magnonic mirror array
Zi-Qi Wang, Yuan-Peng Peng, Yi-Pu Wang +1
Exceptional points (EPs) in non-Hermitian systems are singularities where both eigenvalues and eigenvectors coalesce. In scattering systems, EPs correspond to the merging of scatte…
Synthetically enhanced sensitivity using higher-order exceptional point and coherent perfect absorption
Yao-Dong Hu, Yi-Pu Wang, Rui-Chang Shen +3
Sensors play a crucial role in advanced apparatuses and it is persistently pursued to improve their sensitivities. Recently, the singularity of a non-Hermitian system, known as the…
Giant spin ensembles in waveguide magnonics
Zi-Qi Wang, Yi-Pu Wang, Jiguang Yao +6
The dipole approximation is usually employed to describe light-matter interactions under ordinary conditions. With the development of artificial atomic systems, `giant atom' physic…
