TL;DR
This study uses angle-resolved photoemission to investigate the pseudogap state in La-based cuprates, revealing two opposite dispersing Fermi arcs, which are key to understanding the electronic structure near the 1/8-anomaly.
Contribution
It provides new experimental evidence of Fermi arcs in Nd-LSCO, contributing to the understanding of the pseudogap phase in cuprates.
Findings
Identification of two opposite dispersing Fermi arcs
Discussion of possible scenarios explaining the Fermi arcs
Insights into the electronic structure near the 1/8-anomaly
Abstract
We report an angle resolved photoemission study of the electronic structure of the pseudogap state in \NdLSCO ( K). Two opposite dispersing Fermi arcs are the main result of this study. The several scenarios that can explain this observation are discussed.
