Abstract

We investigate a generalized interpolating Aubry-Andr\'{e}-Fibonacci (IAAF) model with p-wave superconducting pairing. In the Aubry-Andr\'{e} limit, we demonstrate that the system experiences transitions from a pure phase, either extended or critical, to a variety of intermediate phases and ultimately enters a localized phase with increasing potential strength. These intermediate phases include those with coexisting extended and localized states, extended and critical states, localized and critical states and a mix of extended, critical and localized states. Each intermediate phase exhibits at least one type of mobility edge separating different states. As the system approaches the Fibonacci limit, both the extended and localized phases diminish, and the system tends towards a critical phase.
