Abstract
We study the fermionic spectral function in a holographic superconductor model. At zero temperature, there is no horizon and hence the entropy of the system is zero after the backreaction of the condensate is taken into account. We find the system exhibits the famous peak-dip-hump lineshape with a sharp low-energy peak followed by a dip and then a hump at higher energies. This feature is widely observed in the spectrum of several high-Tc superconductors.
