Fermi surface reconstruction in underdoped cuprates: Origin of electron pockets
(American Physical Society, 2018-12-17)
A new phenomenological model is proposed to describe the evolution of the Fermi surface (FS) in a wide range of dopings. It reproduces the key features of the cuprates in the underdoped phase above the superconducting ...
Isotope effect on the superconducting critical temperature of cuprates in the presence of charge order
(Iop Publishing, 2015-11)
Using the large-N limit of the t–J model and also allowing for phonons and the electron–phonon interaction, we study the isotope effect α for coupling constants appropriate for YB2C3O y . We find that α has a minimum at ...
Spin-orbit coupling in the superconducting phase and DDW states of high-T-c cuprates
(Springer, 2010-07-01)
The effects of the spin-orbit coupling are considered for the high T (c) cuprates with asymmetric superconducting gap (SC) and the d-density wave (DDW) phase due to its vital role in the experimental determination of the ...
Competition between spin-induced charge instabilities in underdoped cuprates
(American Physical Society, 2018-12)
We study the static charge correlation function in a one-band model on a square lattice. The Hamiltonian consists of effective hoppings of the electrons between the lattice sites and the Heisenberg Hamiltonian. Approximating ...
Spin-orbit coupling in the superconducting phase and DDW states of high-T-c cuprates
(Springer, 2010-07-01)
The effects of the spin-orbit coupling are considered for the high T (c) cuprates with asymmetric superconducting gap (SC) and the d-density wave (DDW) phase due to its vital role in the experimental determination of the ...
Pseudogap in cuprates driven by d-wave flux-phase order proximity effects: A theoretical analysis from Raman and ARPES experiments
(IOP Publishing, 2014-10)
One of the puzzling characteristics of the pseudogap phase of high-Tc cuprates is the nodal-antinodal dichotomy. While the nodal quasiparticles have a Fermi liquid behaviour, the antinodal ones show non-Fermi liquid features ...
Distinguishing models for the pseudo-gap in cuprate superconductors by probing the spatial distribution of impurity states

Isotope effects in high-T-c cuprate superconductors as support for the bipolaron theory of superconductivity
