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…

Entangling cavity-magnon polaritons by interacting with phonons
Xuan Zuo, Zhi-Yuan Fan, Hang Qian +2
We show how to entangle two cavity-magnon polaritons (CMPs) formed by two strongly coupled microwave cavity and magnon modes. This is realized by introducing vibration phonons, via…
