Hall effect and Fermi surface reconstruction via electron pockets in the high-Tc cuprates

JG Storey - Europhysics Letters, 2016 - iopscience.iop.org
The mechanism by which the Fermi surface of high-T c cuprates undergoes a dramatic
change from a large hole-like barrel to small arcs or pockets on entering the pseudogap …

Fractionalized Fermi liquid in a Kondo-Heisenberg model

AM Tsvelik - Physical Review B, 2016 - APS
The Kondo-Heisenberg model is used as a controllable tool to demonstrate the existence of
a peculiar metallic state with unbroken translational symmetry where the Fermi surface …

Underdoped cuprates as fractionalized Fermi liquids: Transition to superconductivity

EG Moon, S Sachdev - Physical Review B—Condensed Matter and Materials …, 2011 - APS
We model the underdoped cuprates using fermions moving in a background with local
antiferromagnetic order. The antiferromagnetic order fluctuates in orientation, but not in …

Subgap structures and pseudogap in cuprate superconductors: Role of density waves

S Verret, M Charlebois, D Sénéchal, AMS Tremblay - Physical Review B, 2017 - APS
In scanning tunneling microscopy conductance curves, the superconducting gap of cuprates
is sometimes accompanied by small subgap structures at very low energy. This was …

Electron pockets and pseudogap asymmetry observed in the thermopower of underdoped cuprates

JG Storey, JL Tallon, GVM Williams - Europhysics Letters, 2013 - iopscience.iop.org
We calculate the diffusion thermoelectric power of high-T c cuprates using the resonating-
valence-bond spin-liquid model developed by Yang, Rice and Zhang (YRZ). In this model …

Signatures of a momentum independent pseudogap in the electronic density of states and Raman spectroscopy of the underdoped cuprates

JPF LeBlanc - New Journal of Physics, 2014 - iopscience.iop.org
We propose a hybridization phenomenology to describe the pseudogap state of
underdoped cuprates. We show how a momentum independent pseudogap opens …

Effects of a particle-hole asymmetric pseudogap on Bogoliubov quasiparticles

JPF LeBlanc, JP Carbotte, EJ Nicol - Physical Review B—Condensed Matter …, 2011 - APS
We show that in the presence of a pseudogap, the spectral function in the superconducting
state of the underdoped cuprates exhibits additional Bogoliubov quasiparticle peaks at both …

Pseudogap in the Eliashberg approach based on electron‐phonon and electron‐electron‐phonon interaction

R Szczȩśniak, AP Durajski, AM Duda - Annalen der Physik, 2017 - Wiley Online Library
The properties of the superconducting and the anomalous normal state were described by
