The origin of the Fermi arc phenomenon in the pseudogap phase of the underdoped cuprates is studied in the thermal phase fluctuation scenario. An XY-type lattice model with a built in d-wave structure is introduced to describe the phase fluctuation effect in the cuprates. A sharp ridge-like structure in the spectral function A(k, ω = 0) is found to emerge abruptly above the Kosterlitz-Thouless (KT) transition temperature (T(KT)) on the underlying Fermi surface. This ridge-like structure in A(k…

TLDR
It is found that the pair breaking Raman peak depends sensitively on the phase coherence of the pairing order parameter, which provides further support for the thermal phase fluctuation scenario of the pseudogap phase and the KT-type nature of the superconducting transition in underdoped cuprates.
Monte Carlo study of thermal fluctuations and Fermi-arc formation in d-wave superconductors
From the perspective of thermal fluctuations, we investigate the pseudogap phenomena in underdoped high-temperature curpate superconductors. We present a local update Monte Carlo procedure based on…

Vortex-like excitations and the onset of superconducting phase fluctuation in underdoped La2-xSrxCuO4
TLDR
Evidence for vortices (or vortex-like excitations) in La2-xSrxCuO4 at temperatures significantly above the critical temperature is reported.
Evolution of the Fermi surface of d-wave superconductors in the presence of thermal phase fluctuations.
TLDR
It is shown that the electron spectral function develops a square root singularity at low frequencies for wave vectors positioned on the bare Fermi surface and predicts a temperature dependence of the arc length that can partially account for the results of recent angle resolved photoemission experiments.
Evolution of the pseudogap from Fermi arcs to the nodal liquid
The response of a material to external stimuli depends on its low-energy excitations. In conventional metals, these excitations are electrons on the Fermi surface—a contour in momentum (k) space that…

This article reviews the physics of high-temperature superconductors from the point of view of the doping of a Mott insulator. The basic electronic structure of cuprates is reviewed, emphasizing the…
Quantum oscillations and the Fermi surface in an underdoped high-Tc superconductor
TLDR
The observation of quantum oscillations in the electrical resistance of the oxygen-ordered copper oxide YBa2Cu3O6.5 establishes the existence of a well-defined Fermi surface in the ground state of underdoped copper oxides, once superconductivity is suppressed by a magnetic field.
Spectroscopic evidence for a pseudogap in the normal state of underdoped high-Tc superconductors
IT is well known that BCS mean-field theory is remarkably successful in describing conventional superconductors. A central concept of BCS theory is the energy gap in the electronic excitation…

THE superconducting state of a metal is characterized by a complex order parameter with an amplitude and a phase. In the BCS-Eliashberg mean-field theory1, which is a very good approximation for…
Fermi arcs in the superconducting clustered state for underdoped cuprate superconductors.
TLDR
The one-particle spectral function of a state formed by superconducting (SC) clusters is studied via Monte Carlo techniques, which shows that this state is stabilized by competition with the antiferromagnetism expected to be present in the cuprates and after quenched disorder is introduced.
