Phenomenological Transport Equation for the Cuprate Metals

TL;DR

This paper introduces a phenomenological transport equation for cuprate metals that explains the presence of two distinct relaxation times by considering scattering processes that differentiate between charge conjugation even and odd currents.

Contribution

It presents a novel transport equation capturing the dual relaxation times in cuprates, linking scattering processes to charge conjugation symmetry.

Findings

Two relaxation times arise from different scattering processes.

The transport equation explains experimental observations in cuprates.

Theoretical implications for charge conjugation symmetry in transport.

Abstract

We observe that the appearance of two transport relaxation times in the various transport coefficients of cuprate metals may be understood in terms of scattering processes that discriminate between currents that are even, or odd under the charge conjugation operator. We develop a transport equation that illustrates these ideas and discuss its experimental and theoretical consequences.
