Thermodynamic transitions in inhomogeneous d-wave superconductors
نویسندگان
چکیده
We study the spectral and thermodynamic properties of inhomogeneous d-wave superconductors within a model where the inhomogeneity originates from atomic-scale pair disorder. This assumption has been shown to be consistent with the small charge and large gap modulations observed by scanning tunneling spectroscopy on Bi2Sr2CaCu2O8+x. Here we calculate the specific heat within the same model, and show that it gives a transition width comparable to those found in experiments on this material. This suggests that nanoscale inhomogeneity is a bulk property of the Bi2Sr2CaCu2O8+x materials.

اتصال جوزفسون بین ابررساناهای دمای بالا با ضریب عبور اختیاری
In this paper, a dc Josephson junction between two singlet superconductors (d-wave and s-wave) with arbitrary reflection coefficient has been investigated theoretically. For the case of high Tc superconductors, the c-axes are parallel to an interface with finite transparency and their ab-planes have a mis-orientation. The physics of potential barrier will be demonstrated by a transparency coeff...
متن کاملRelaxation and Thermal Conductivity of Hot and Thermal Quasiparticles and Fermi Liquid Interactions in d-wave Superconductors
In this paper, we calculate theoretically the relaxation rates of hot, thermal and antinodal quasiparticles by using Fermi’s golden rule. The transition probabilities at low temperatures express in terms of Bogoliubov coefficients, singlet and triplet scattering amplitudes and dimensionless Landau parameters. The values of Landau parameters may be determined by comparison with the experimental ...
متن کاملTheory of quantum metal to superconductor transitions in highly conducting systems
We derive the theory of the quantum (zero temperature) superconductor to metal transition in disordered materials when the resistance of the normal metal near criticality is small compared to the quantum of resistivity. This can occur most readily in situations in which “Anderson’s theorem” does not apply. We explicitly study the transition in superconductor-metal composites, in an swave superc...
متن کاملGapless Fermi surfaces of anisotropic multiband superconductors in a magnetic field.
We propose that a new state with a fully gapless Fermi surface appears in quasi-2D multiband superconductors in magnetic field applied parallel to the plane. It is characterized by a paramagnetic moment caused by a finite density of states on the open Fermi surface. We calculate thermodynamic and magnetic properties of the gapless state for both s-wave and d-wave cases, and discuss the details ...
متن کاملQuantum phase transitions in d-wave superconductors
Motivated by the strong, low temperature damping of nodal quasiparticles observed in some cuprate superconductors, we study quantum phase transitions in d(x(2)-y(2)) superconductors with a spin-singlet, zero momentum, fermion bilinear order parameter. We present a complete, group-theoretic classification of such transitions into seven distinct cases (including cases with nematic order) and anal...
