Query: Holographic Fermi surfaces near quantum phase transitions   We study holographic Fermi surfaces coupled to a bosonic degree of freedom
using the gauge/gravity correspondence. The gravity background is a charged
black hole in asymptotically AdS spacetime. We introduce a neutral scalar field
with parameters such that the system is at a quantum phase transition point. We
further introduce a Dirac field and couple it to the scalar. At finite N, these
fields interact in the bulk. We compute the bulk one-loop contribution to the
boundary fermionic self-energies at various quantum phase transition points.
The results would give an embedding of the marginal Fermi liquid model by Varma
et al. into a holographic context. We comment on important issues that arise at
low energies when one wants to take the one-loop results more seriously.
