Short-ranged and short-lived charge-density-wave order and pseudogap features in underdoped cuprates superconductors

TL;DR

This paper demonstrates that the pseudogap phenomena and related features in underdoped cuprates can be explained by short-range, short-lived charge-density-wave order within the t-J model, supporting a non-superconducting origin.

Contribution

It provides a theoretical explanation for pseudogap features using the t-J model with self-energy effects near a d charge-density-wave instability, aligning with recent experimental findings.

Findings

Features of pseudogap explained by short-range charge order

Supports non-superconducting origin of pseudogap

Aligns with recent ARPES experimental results

Abstract

The pseudogap phase of high-$T_c$ cuprates is controversially attributed to preformed pairs or to a phase which coexists and competes with superconductivity. One of the challenges is to develop theoretical and experimental studies in order to distinguish between both proposals. Very recently, researchers at Stanford have reported [M. Hashimoto {\it et al.}, Nat. Phys. {\bf 6}, 414 (2010); R.-H. He {\it et al.}, Science {\bf 331}, 1579 (2011)] angle-resolved photoemission spectroscopy experiments on Pb-Bi2201 supporting the point of view that the pseudogap is distinct from superconductivity and associated to a spacial symmetry breaking without long-range order. In this paper we show that many features reported by these experiments can be described in the framework of the t-J model considering self-energy effects in the proximity to a d charge-density-wave instability.
