Magnetic oscillations in a holographic liquid

TL;DR

This paper explores magnetic oscillations in strongly correlated electron systems using a holographic model, revealing differences from traditional Fermi liquid behavior through a charged fluid in an anti-de-Sitter spacetime.

Contribution

It introduces a holographic approach with a charged spin 1/2 fluid outside a black brane, avoiding probe fermions, to study magnetic oscillations in strongly correlated systems.

Findings

Magnetic oscillations are observed without probe fermions.

Oscillations differ from Fermi liquid predictions.

Back-reaction influences the dual field theory behavior.

Abstract

We present a holographic perspective on magnetic oscillations in strongly correlated electron systems via a fluid of charged spin 1/2 particles outside a black brane in an asymptotically anti-de-Sitter spacetime. The resulting back-reaction on the spacetime geometry and bulk gauge field gives rise to magnetic oscillations in the dual field theory, which can be directly studied without introducing probe fermions, and which differ from those predicted by Fermi liquid theory.
