We show that incommensurability can enhance superconductivity in one dimensional
quasiperiodic systems with s-wave pairing. As a parent model, we use a generalized Aubry-
Andr\'e model that includes quasiperiodic modulations both in the potential and in the
hoppings. In the absence of interactions, the model contains extended, critical and localized
phases for incommensurate modulations. Our results reveal that in a substantial region
inside the parent critical phase, there is a significant increase of the superconducting critical …
