Anderson localization transition in a robust $\mathcal{P}\mathcal{T}$-symmetric phase of a generalized Aubry-Andre model

Sebastian Schiffer, Xia-Ji Liu, Hui Hu +1

We study a generalized Aubry-Andre model that obeys $\mathcal{P}\mathcal{T}$-symmetry. We observe a robust $\mathcal{P}\mathcal{T}$-symmetric phase with respect to system size and disorder strength, w…
