TL;DR

This paper presents an analytic self-consistent solution for a 2D mean-field model that describes coexisting pair density waves and density waves, revealing insights into high-temperature superconductor phenomena.

Contribution

It introduces a novel analytic solution for a 2D mean-field model with coexisting PDW, SDW, and CDW, matching experimental observations in high-temperature superconductors.

Findings

PDW and CDW share the same periodicity

The solution exhibits a pseudogap in the spectrum

Coexistence of multiple density waves in the ground state

Abstract

In the self-consistent approximation for the two-dimensional mean-field model we found an analytic solution for the ground state with a coexisting d-wave symmetric bond ordered pair density wave (PDW) and spin (SDW) or charge (CDW) density waves, as observed in some high-temperature superconductors. In particular, the solution gives the same periodicity for CDW and PDW, and a pseudogap in the Fermi-excitation spectrum.
