Temperature Dependence Of Cuprate Superconductors’ Order Parameter
A model of charged hole-pair bosons, with long range Coulomb interactions and very weak interlayer coupling, is used to calculate the order parameter Φ of underdoped cuprates. Model parameters are extracted from experimental superfluid densities and plasma frequencies. The temperature dependence Φ(T ) is characterized by a ’trapezoidal’ shape. At low temperatures, it declines slowly due to harm...
متن کاملFluctuation Effects And Order Parameter Symmetry In The Cuprate Superconductors
Effect of phase fluctuations on superconducting states with anisotropic order parameters is studied in a BCS like lattice model of cuprate superconductors. The degradation of the mean field transition temperature due to phase fluctuations is estimated within a Kosterlitz-Thouless scenario. Values of the interaction parameters for optimal doping, corresponding to a stable superconducting state o...
متن کاملTuning order in cuprate superconductors
In 1986, superconductivity—the ability to transport electrical current without significant resistance—was discovered in cuprate compounds. These materials have fascinated physicists ever since, in part because of the high critical temperatures (Tc’s) below which superconductivity is present and the consequent promise of technological applications. However, cuprate superconductivity also raises ...
متن کاملMixed state microwave resistivity of cuprate superconductors
We present a compared experimental investigation of the (a, b) plane vortex-state complex resistivity at 48 GHz in YBa2Cu3O7−δ, SmBa2Cu3O7−δ and Bi2Sr2CaCu2O8+x. In YBa2Cu3O7−δ and SmBa2Cu3O7−δ the field dependence of the response can be consistently described by a combination of flux flow and strong pair breaking due to the presence of lines of nodes in the gap. In Bi2Sr2CaCu2O8+x, by contrast...
متن کاملModel of quasiparticles coupled to a frequency-dependent charge-density-wave order parameter in cuprate superconductors.
We investigate a model where superconducting electrons are coupled to a frequency dependent charge-density wave order parameter Delta_{r}(omega). Our approach can reconcile the simultaneous existence of low-energy Bogoljubov quasiparticles and high energy electronic order as observed in scanning tunneling microscopy (STM) experiments. The theory accounts for the contrast reversal in the STM spe...
