Abstract
We study the effect of disorder in a holographic superconductor by introducing a quasiperiodic chemical potential. When the condensation of the superconductor is sufficiently small compared with the strength of disorder, we find that there exists a discontinuous phase transition from superconducting state to normal state with increasing disorder strength. For relatively large condensation, we find that disorder suppresses but does not completely destroy superconductivity.
