A complex phase in the quasiperiodic potential of a non-Hermitian Aubry-André chain controls whether eigenstates sit at an interface (skin effect) or near the excitation site (Anderson localization), and a topolectrical circuit reproduces this tuning in its voltage profile.

Controlled probing of localization effects in the non-Hermitian Aubry-Andr\'e model via topolectrical circuits
A complex phase in the quasiperiodic potential of a non-Hermitian Aubry-André chain controls whether eigenstates sit at an interface (skin effect) or near the excitation site (Anderson localization), and a topolectrical circuit reproduces this tuning in its voltage profile.
