We report on a potentially new class of non-Fermi liquids in (2+1)-dimensions. They are identified via the response functions of composite fermionic operators in a class of strongly interacting quantum field theories at finite density, computed using the AdS/CFT correspondence. We find strong evidence of Fermi surfaces: gapless fermionic excitations at discrete shells in momentum space. The spectral weight exhibits novel phenomena, including particle-hole asymmetry, discrete scale invariance, and scaling behavior consistent with that of a critical Fermi surface postulated by Senthil.

Peculiar properties of a charged dilatonic black hole in AdS 5 (2009, background): “In the conventions of [5, 7], which we also adopt, energy equal to the Fermi energy corresponds to frequency equal to 0.”
Holographic Fermi surfaces and entanglement entropy (2011, methodology): “Recently, there have been exciting progresses on the holographic realizations of Fermi surfaces using the AdS/CFT such as the ones using the Reissner-Nordström black holes [2–7] and the starlike solutions, called electron stars [8–12].”
Electron stars for holographic metallic criticality (2010, unknown): “ nature of the charge carriers, such as a Fermi surface in the case of fermions. A Fermi surface appears not to be inherent to the gravitational geometry, but depends on the nature of external probes [21, 22, 23, 24, 25]. It is perhaps fortunate, therefore, that low temperature charged AdS black hol”
