A bstractWe use holography to study the ground state of a system with interacting bosonic and fermionic degrees of freedom at finite density. The gravitational model consists of Einstein-Maxwell gravity coupled to a perfect fluid of charged fermions and to a charged scalar field which interact through a current-current interaction. When the scalar field is non-trivial, in addition to compact electron stars, the screening of the fermion electric charge by the scalar condensate allows the… 

Strongly-coupled systems in gauge/gravity duality

As an introduction, we present the original formulation of the AdS/CFT correspondence, between N = 4 Super Yang-Mills theory with gauge group SU(N) and type IIB string theory on AdS5 x S5. In a first

Exciton-driven quantum phase transitions in holography

We study phase transitions driven by fermionic double-trace deformations in gauge-gravity duality. Both the strength of the double trace deformation and the infrared conformal dimension/self-energy

Intermediate scalings in holographic RG flows and conductivities

A bstractWe construct numerically finite density domain-wall solutions which interpolate between two AdS4 fixed points and exhibit an intermediate regime of hyperscaling violation, with or without

Holographic Fermi liquids in a spontaneously generated lattice

We discuss fermions in a spontaneously generated holographic lattice background. The lattice structure at the boundary is generated by introducing a higher-derivative interaction term between a

Classical conformal blocks

We give a simple iterative procedure to compute the classical conformal blocks on the sphere to all order in the modulus.

Chiral ground states in a frustrated holographic superconductor

A bstractFrustration is an important phenomenon in condensed matter physics because it can introduce a new order parameter such as chirality. Towards understanding a mechanism of the frustration in

Spectral probes of the holographic Fermi ground state: Dialing between the electron star and AdS Dirac hair

We argue that the electron star and the anti\char21{}de Sitter (AdS) Dirac hair solution are two limits of the free charged Fermi gas in AdS. Spectral functions of holographic duals to probe fermions

Fractionalization of holographic Fermi surfaces

Zero temperature states of matter at finite charge density are holographically described by a spacetime with an asymptotic electric flux. This flux can be sourced either by explicit charged matter

Emergent quantum criticality, Fermi surfaces, and AdS2

Gravity solutions dual to d-dimensional field theories at finite charge density have a near-horizon region, which is AdS{sub 2}xR{sup d-1}. The scale invariance of the AdS{sub 2} region implies that

Stellar spectroscopy: Fermions and holographic Lifshitz criticality

Electron stars are fluids of charged fermions in Anti-de Sitter spacetime. They are candidate holographic duals for gauge theories at finite charge density and exhibit emergent Lifshitz scaling at

Electron stars for holographic metallic criticality

We refer to the ground state of a gravitating, charged ideal fluid of fermions held at a finite chemical potential as an ''electron star.'' In a holographic setting, electron stars are candidate

Competing orders in M-theory: superfluids, stripes and metamagnetism

A bstractWe analyse the infinite class of d = 3 CFTs dual to skew-whiffed AdS4 × SE7 solutions of D = 11 supergravity at finite temperature and charge density and in the presence of a magnetic field.

Holographic metals and the fractionalized fermi liquid.

There is a close correspondence between the physical properties of holographic metals near charged black holes in anti-de Sitter (AdS) space, and the fractionalized Fermi liquid phase of the lattice Anderson model, implying that certain mean-field gapless spin liquids are states of matter at nonzero density realizing the near-horizon, AdS₂ × R² physics of Reissner-Nordström black holes.

Zero temperature limit of holographic superconductors

We consider holographic superconductors whose bulk description consists of gravity minimally coupled to a Maxwell field and charged scalar field with general potential. We give an analytic argument

Compressible Quantum Phases from Conformal Field Theories in 2+1 Dimensions

Conformal field theories (CFTs) with a globally conserved U(1) charge Q can be deformed into compressible phases by modifying their Hamiltonian, H, by a chemical potential H -> H - \mu Q. We study

Dressing the electron star in a holographic superconductor

A bstractWe construct new asymptotically AdS4 solutions dual to 2+1 CFTs at finite density and zero temperature by combining the ingredients of the electron star and the holographic superconductor.
