Electron-fluctuation interaction in a non-Fermi superconductor

TL;DR

This paper investigates how amplitude fluctuations in a non-Fermi superconductor affect the energy spectrum of a 2D Anderson non-Fermi system, revealing temperature-dependent pseudogap behavior.

Contribution

It introduces a study of classical amplitude fluctuations' impact on the energy spectrum in a non-Fermi superconductor, highlighting pseudogap formation.

Findings

Amplitude fluctuations induce a temperature-dependent pseudogap.

Classical fluctuations significantly modify the fermionic excitation spectrum.

The study provides insights into non-Fermi superconductor behavior.

Abstract

We studied the influence of the amplitude fluctuations of a non-Fermi superconductor on the energy spectrum of the 2D Anderson non-Fermi system. The classical fluctuations give a temperature dependence in the pseudogap induced in the fermionic excitations.
