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…
Time-Varying Strong Coupling and Its Induced Time Diffraction of Magnon Modes
Jinwei Rao, Yi-Pu Wang, Zhijian Chen +7
Time-varying media break the temporal translation symmetry of wave propagation in materials, enabling advanced wave manipulations. However, this novel phenomenon has been rarely ex…
Gain-Loss Coupled Systems
Chunlei Zhang, Mun Kim, Yi-Hui Zhang +7
Achieving oscillations with small dimensions, high power, high coherence, and low phase noise has been a long-standing goal in wave physics, driving innovations across classical el…
