Nonreciprocal slow or fast light in anti-$\mathcal{P}\mathcal{T}$-symmetric optomechanics

Meiyu Peng, Huilai Zhang, Qian Zhang +3

Non-Hermitian systems with anti-parity-time ($\mathcal{A}\mathcal{P}\mathcal{T}$) symmetry have revealed rich physics beyond conventional systems. Here, we study optomechanics in an $\mathcal{A}\mathcal{P}\mathcal{T}$-sy…
