Manipulating spectral transitions and photonic transmission in a non-Hermitian optical system through nanoparticle perturbations

Bo-Wang Zhang, Cheng Shang, J. Y. Sun +2

In recent years, extensive research has been dedicated to the study of parity-time ($\mathcal{P}\mathcal{T}$) symmetry, which involves the engineered balance of gain and loss in non-Hermitia…
