Nernst effect in poor conductors and the cuprate superconductors
A. S. Alexandrov, V. N. Zavaritsky
TL;DR
This paper models the Nernst effect in disordered conductors near the mobility edge, explaining the anomalous signals in high-temperature cuprate superconductors through interference of different carrier contributions.
Contribution
It introduces a theoretical calculation of the Nernst signal considering both itinerant and localized carriers in disordered conductors, explaining experimental observations in cuprates.
Findings
Nernst signal depends strongly on temperature and magnetic field.
The model quantitatively matches the anomalous Nernst signals in high-Tc cuprates.
Interference of carrier contributions explains the observed effects.
Abstract
We calculate the Nernst signal in disordered conductors with the chemical potential near the mobility edge. The Nernst effect originates from interference of itinerant and localised-carrier contributions to the thermomagnetic transport. It reveals a strong temperature and magnetic field dependence, which describes quantitatively the anomalous Nernst signal in high-Tc cuprates.
