Pseudogap suppression by competition with superconductivity in La-based cuprates

Physical Review Research, 2022
We carried out a comprehensive high-resolution angle-resolved photoemission spectroscopy (ARPES) study of the pseudogap interplay with superconductivity in La-based cuprates.

Low-dimensional fluctuations and pseudogap in Gaudin-Yang Fermi gases

Physical Review Research, 2020
The pseudogap is a ubiquitous phenomenon in strongly correlated systems, such as high-T_{c} superconductors, ultracold atoms, and nuclear physics. Whereas pairing fluctuations inducing the pseudogap are known to be enhanced in low-dimensional systems ...

Pseudogap in electron-doped cuprates as a thermal precursor to magnetism [PDF]

Nature Communications
We study pseudogap behavior in a metal near an antiferromagnetic instability and apply the results to electron-doped cuprates. We associate pseudogap behavior with thermal magnetic fluctuations and compute the fermionic self-energy along the Fermi ...

Fermi liquid-like behaviour of cuprates in the pseudogap phase simulated via T-dependent electron-boson spectral density [PDF]

Scientific Reports, 2023
We investigated the temperature- and frequency-dependent optical scattering rates in the pseudogap phase of cuprates using model pseudogap and electron-boson spectral density (EBSD) functions.

Fermi surface and pseudogap in highly doped Sr2IrO4 [PDF]

npj Quantum Materials
The fate of the Fermi surface in bulk electron-doped Sr2IrO4 remains elusive, as does the origin and extension of its pseudogap phase. Here, we use high-resolution angle-resolved photoelectron spectroscopy (ARPES) to investigate the electronic structure ...

Temperature-Independent Cuprate Pseudogap from Planar Oxygen NMR

Condensed Matter, 2020
Planar oxygen nuclear magnetic resonance (NMR) relaxation and shift data from all cuprate superconductors available in the literature are analyzed. They reveal a temperature-independent pseudogap at the Fermi surface, which increases with decreasing ...

The pseudogap in high-temperature superconductors: an experimental survey

Reports on Progress in Physics, 1999
We present an experimental review of the nature of the pseudogap in the cuprate superconductors. Evidence from various experimental techniques points to a common phenomenology.

Models of the pseudogap state in cuprates [PDF]

Physica C: Superconductivity, 2000
We review a certain class of ("nearly") exactly solvable models of electronic spectrum of two-dimensional systems with fluctuations of short range order of "dielectric" (e.g. antiferromagnetic) or "superconducting" type, leading to the formation of anisotropic pseudogap state on certain parts of the Fermi surface.

Effect of Magnetic field on the Pseudogap Phenomena in High-TcCuprates

Journal of the Physical Society of Japan, 2000
We theoretically investigate the effect of magnetic field on the pseudogap phenomena in High-Tc cuprates. The obtained results well explain the experimental results including their doping dependences. In our previous paper (J. Phys. Soc. Jpn.
