Fermi arc in p-wave holographic superconductors

Abstract

Abstract We have investigated the fermionic spectral function in p-wave holographic superconductors. We show that the vector model with minimal coupling reveals a p-wave spectral function with Fermi arc. This should be contrasted with the previous investigation where p-wave arc was demonstrated in the presence of a tensor field. We study the momentum dependent order parameter, the ω-gap in the real part of the conductivity and the fermion spectral function. In addition, we juxtapose the fermionic spectral gap with the order parameter in the holographic set. We demonstrate the impact of coupling constants, temperature and chemical potential on the spectral function.
