Evidence for a small hole pocket in the Fermi surface of underdoped YBa2Cu3Oy
In underdoped cuprate superconductors, the Fermi surface undergoes a reconstruction that produces a small electron pocket, but whether there is another, as yet, undetected portion to the Fermi surface is unknown. Establishing the complete topology of the Fermi surface is key to identifying the mechanism responsible for its reconstruction. Here we report evidence for a second Fermi pocket in und...
متن کاملSum rules and interlayer infrared response of the high temperature YBa2Cu3Oy superconductor in an external magnetic field.
We present infrared magneto-optical measurements of the c-axis conductivity of YBa2Cu3Oy in both the underdoped (y=6.67 and 6.75) and optimally doped (y=6.95) regimes. We show that modest c-axis magnetic fields radically modify the condensate formation and restore conventional BCS-like energetics. Additionally, we demonstrate the pivotal role of interplane coherence in the anomalous high-energy...
متن کاملنظریه میدان میانگین برای ابررسانایی مسی دمای بالا
Two decades ago the epoch making discovery of high Tc cuprate superconductivity by Bednorz and Müller shocked the world’s superconductivity community. However, already in 1979 and 1980, the first heavy fermion superconductor CeCu2Si2 and organic superconductor (TMTSF)2PF6 have been discovered respectively. Also we know now that all these superconductors are unconventional and nodal. Further t...
متن کاملDoping dependence of superconducting gap in YBa2Cu3Oy from universal heat transport
Thermal transport in the T → 0 limit was measured as a function of doping in high-quality single crystals of the cuprate superconductor YBa2Cu3Oy. The residual linear term κ0/T is found to decrease as one moves from the overdoped regime towards the Mott insulator region of the phase diagram. The doping dependence of the lowenergy quasiparticle gap extracted from κ0/T is seen to scale closely wi...
متن کاملDelocalized fermions in underdoped cuprate superconductors.
Low-temperature heat transport was used to investigate the ground state of high-purity single crystals of the lightly doped cuprate YBa2Cu3O6.33. Samples were measured with doping concentrations on either side of the superconducting phase boundary. We report the observation of delocalized fermionic excitations at zero energy in the nonsuperconducting state, which shows that the ground state of ...
