Possible Quasi-One-Dimensional Fermi Surface in La_{2-x}Sr_{x}CuO_4

TL;DR

This paper proposes that La_{2-x}Sr_{x}CuO_4 has a quasi-one-dimensional Fermi surface structure, explaining conflicting experimental observations from ARPES and neutron scattering by suggesting alternating q-1d directions along the c-axis.

Contribution

It introduces a novel quasi-one-dimensional Fermi surface model to reconcile different experimental findings in La_{2-x}Sr_{x}CuO_4.

Abstract

To reconcile the two experimental findings on La_{2-x}Sr_{x}CuO_4, namely, Fermi surface (FS) observed by angle-resolved photoemission spectroscopy and sharp incommensurate magnetic peaks by neutron scattering, we propose a picture that a quasi-one-dimensional FS (q-1dFS) is realized in each CuO_{2} plane whose q-1d direction alternates along the c-axis.
