A Fermi Sea of Heavy Electrons (a Kondo Lattice) is Never a Fermi Liquid

TL;DR

The paper argues that the Fermi surface in heavy electron metals cannot be a traditional Fermi liquid due to a fundamental contradiction related to electron occupancy.

Contribution

It introduces a contradiction in the assumption that the Fermi surface in heavy electron metals signifies a finite occupancy jump, challenging conventional Fermi liquid theory.

Findings

Fermi sea of heavy electrons cannot be a Fermi liquid

Contradiction arises from occupancy assumptions

Implications for heavy electron metal theories

Abstract

I demonstrate a contradiction which arises if we assume that the Fermi surface in a heavy electron metal represents a finite jump in occupancy.
