Superconducting Gap Nodal Surface and Fermi Surface: their partial overlap in cuprates
An actively debated issue in the experimental study of high-Tc cuprate superconductors [1,11,16] is the symmetry and detailed k-dependence of the gap function ∆k. We suggest a form of ∆k, based on physical arguments and numerical results, which is in qualitative agreement with the available experimental results. The form that we suggest is a generalised version of an early suggestion of Anderso...
متن کاملFermi surface dichotomy of the superconducting gap and pseudogap in underdoped pnictides.
High-temperature superconductivity in iron-arsenic materials (pnictides) near an antiferromagnetic phase raises the possibility of spin-fluctuation-mediated pairing. However, the interplay between antiferromagnetic fluctuations and superconductivity remains unclear in the underdoped regime, which is closer to the antiferromagnetic phase. Here we report that the superconducting gap of underdoped...
متن کاملTheoretical Fermi-Surface Properties and Superconducting Parameters for K3C60.
Quantitative theories of superconductivity in alkali-doped C(60) require an accurate and detailed description of the Fermi surface. First-principles calculations of Fermi-surface properties and electronic parameters for K(3)C(60), the prototype fulleride-superconductor, are reported. The Fermi surface has two sheets; the first is free-electron-like, and the second is multiply-connected, forming...
متن کاملFermi surface of superconducting LaFePO determined from quantum oscillations.
We report extensive measurements of quantum oscillations in the normal state of the Fe-based superconductor LaFePO, (T(c) approximately 6 K) using low temperature torque magnetometry and transport in high static magnetic fields (45 T). We find that the Fermi surface is in broad agreement with the band-structure calculations with the quasiparticle mass enhanced by a factor approximately 2. The q...
متن کاملThe Fermi surface of underdoped high-Tc superconducting cuprates
The coexistence of π-flux state and d-wave RVB state is considered in this paper within the slave boson approach. A critical value of doping concentration δc is found, below which the coexisting π-flux and d-wave RVB state is favored in energy. The pseudo Fermi surface of spinons and the physical electron spectral function are calculated. A clear Fermi-level crossing is found along the (0,0) to...
