General scaling arguments, and the behavior of the thermal entropy density, are shown to lead to an infrared metric holographically representing a compressible state with hidden Fermi surfaces. This metric is characterized by a general dynamic critical exponent, z, and a specific hyperscaling violation exponent, \theta. The same metric exhibits a logarithmic violation of the area law of entanglement entropy, as shown recently by Ogawa et al. (arXiv:1111.1023). We study the dependence of the entanglement entropy on the shape of the entangling region(s), on the total charge density, on temperature, and on the presence of additional visible Fermi surfaces of gauge-neutral fermions; for the latter computations, we realize the needed metric in an Einstein-Maxwell-dilaton theory. All our results support the proposal that the holographic theory describes a metallic state with hidden Fermi surfaces of fermions carrying gauge charges of deconfined gauge fields.

Improved Holographic QCD on a Curved Background: an Application of Dynamical System Theory in Holography
For the critical exponent b=b_c, IHQCD (alpha=1/2) admits only regular endpoint-type solutions at positive curvature and singular acceptable solutions at negative curvature, so the curvature-driven transition occurs at R=0.

The negativity contour: a quasi-local measure of entanglement for mixed states
The authors define a computable negativity contour via a derivative of logarithmic negativity, verify it against a Gaussian ansatz, and apply it to Fermi surfaces, holographic non-Fermi liquids, and thermalization.

Spectral weight in holography with momentum relaxation
In holographic superfluids with axion-induced momentum relaxation, the finite-momentum instability is strengthened and low-energy spectral weight, including Fermi shells, is suppressed.
