Incoherent Tunneling Amplitude in High Tc Cuprates

TL;DR

This paper revises and extends previous work on tunneling spectra in high-temperature cuprate superconductors, focusing on incoherent contributions arising from quasiparticle decay processes.

Contribution

It provides corrected details and new methods for calculating the incoherent tunneling spectrum, emphasizing the role of spin-flip decay in quasiparticle dynamics.

Findings

Corrected previous spectrum calculations

Presented recipes for incoherent spectrum analysis

Highlighted the significance of spin-flip decay processes

Abstract

A 2004 paper of Anderson and Ong calculated the asymmetric coherent spectrum of point-contact tunneling into a Gutzwiller-projected superconductor. We here correct some details of that paper and present recipes for the manyquasiparticle, incoherent spectrum, the major portion of which results from the spin-flip decay of the injected quasiparticle. An illustrative example is shown.
