Beware of the pseudogap

TL;DR

This paper clarifies the nature of the pseudogap phase in high-temperature cuprate superconductors by demonstrating that both a competing state and a precursor-to-superconductivity state coexist, resolving previous conflicting experimental evidence.

Contribution

It provides conclusive experimental evidence that both the competing state and precursor-to-superconductivity state exist simultaneously in the pseudogap phase.

Findings

Both states coexist in the pseudogap phase

Experimental evidence resolves previous conflicting interpretations

Clarifies the nature of the pseudogap in cuprate superconductors

Abstract

In the pseudogap phase of a high-temperature cuprate superconductor, conflicting evidence from different experiments points to a competing state or a precursor-to-superconductivity state. One single experiment now determines that both states exist.
