Correlation of pseudogap, superconducting ordering and superconducting fluctuations with electron–phonon interactions in Bi2Sr2CaCu2O8+δ

New Journal of Physics, 2022
The relationship between anomalous pseudogap and superconducting states is a fascinating but controversial subject in high temperature superconductors.

Pseudogaps in an Incoherent Metal [PDF]

Physical Review Letters, 2002
How are the properties of a metal changed by strong inelastic scattering? We investigate this question within the two-dimensional t-J model using extended dynamical mean field theory and a generalized non-crossing approximation. Short-ranged antiferromagnetic fluctuations lead to a strongly incoherent single particle dynamics, large entropy and ...

Electronic nature of the pseudogap in electron-doped Sr2IrO4

npj Quantum Materials, 2022
In high-temperature (T c) cuprate superconductors, many exotic phenomena are rooted in the enigmatic pseudogap state, which has been interpreted as consisting of preformed Cooper pairs or competing orders or a combination thereof.

Three studies in high-Tc cuprates

New Journal of Physics, 2022
We investigate three fundamental issues in the physics of high-Tc cuprates, from the perspective of a recently proposed comprehensive theory for these materials. (a) Orbital ordering × superconductivity.

Effect of Van Hove singularities in the onset of pseudogap states in Mott insulators

Physical Review Research, 2020
The Mott insulating phase of parent compounds is frequently taken as a starting point for underdoped high-T_{c} cuprate superconductors. In particular, the pseudogap state is often considered as deriving from the Mott insulator.

Scattering interference signature of a pair density wave state in the cuprate pseudogap phase

Nature Communications, 2021
The pseudogap phase in cuprate superconductors is predicted to be a pair density wave state (PDW) but experimental evidence has been lacking. Here, the authors detect the temperature evolution of energy gap modulations and scattering interference ...

Pseudogap from ARPES experiment: three gaps in cuprates and topological superconductivity [PDF]

, 2015
A term first coined by Mott back in 1968 a `pseudogap' is the depletion of the electronic density of states at the Fermi level, and pseudogaps have been observed in many systems. However, since the discovery of the high temperature superconductors (HTSC)
