A quantum electron star
Andrea Allais, John McGreevy, S. Josephine Suh
TL;DR
This paper develops a holographic model of a quantum electron star, where a Fermi liquid interacts with a conformal field theory, showing that quasiparticles persist in this coupled state.
Contribution
It introduces a holographic construction of a quantum electron star, combining a Fermi liquid with a CFT in a novel way that preserves quasiparticles.
Findings
The bulk solution is a quantum gas of fermions supported by electrostatic repulsion.
Quasiparticles from the Fermi liquid survive the coupling to the CFT.
The model provides insights into strongly correlated electron systems.
Abstract
We construct and probe a holographic description of state of matter which results from coupling a Fermi liquid to a relativistic conformal field theory (CFT). The bulk solution is described by a quantum gas of fermions supported from collapse into the gravitational well of AdS by their own electrostatic repulsion. In the probe limit studied here, the Landau quasiparticles survive this coupling to a CFT.
