Abstract
We study a generalized Aubry-André model that obeys symmetry. We observe a robust -symmetric phase with respect to system size and disorder strength, where all eigenvalues are real despite the Hamiltonian being non-Hermitian. This robust -symmetric phase can support an Anderson localization transition, giving a rich phase diagram as a result of the interplay between disorder and symmetry. Our model provides a perfect platform to study disorder-driven localization phenomena in a -symmetric system.
