Fermi arcs from holography

Understand

In this paper, we find mechanisms for the generation of Fermi arcs using the gauge/gravity correspondence.

• The gravity background is taken to be a charged black hole with vector hair in asymptotically AdS4 spacetime.
• The response function of fermion probes exhibits a p-wave gap in the dual superconductor.
• We couple the fermions to a charged rank-two antisymmetric field.
