Gravitationally dressed Fermi Liquids, Quasiunparticles and High Tc Superconductivity

TL;DR

This paper introduces the concept of gravitationally dressed Fermi liquids to describe the normal state of high Tc superconductors, distinguishing between weakly and strongly dressed types with different excitations.

Contribution

It proposes a new theoretical framework of gravitationally dressed Fermi liquids, extending Fermi liquid theory to include quasiunparticle excitations relevant for high Tc superconductivity.

Findings

Weakly dressed Fermi liquids align with canonical Fermi liquid theory.

Strongly dressed Fermi liquids generalize Luttinger liquids to higher dimensions.

The framework supports effective gravitationally dressed Landau-Ginsburg descriptions.

Abstract

We clarify the new concept of gravitationally dressed Fermi liquids we have proposed to describe the normal state of high Tc superconductors. In this note we distinguish between weakly gravitationally dressed Fermi liquids which fall in the class of the canonical Fermi liquid theory (with quasiparticle excitations), and strongly gravitationally dressed Fermi liquids (with quasiunparticle excitations) which represent the high dimensional generalization of Luttinger liquids, with specific features. Such weakly or strongly gravitationally dressed Fermi liquids lead naturally to the previously proposed effective (weak or strong) gravitationally dressed Landau-Ginsburg description of either ordinary or high Tc superconductors.
