Induction of non-d-wave order-parameter components by currents in d-wave superconductors [PDF]
Physical Review B, 1996 It is shown, within the framework of the Ginzburg-Landau theory for a superconductor with d_{x^2-y^2} symmetry, that the passing of a supercurrent through the sample results, in general, in the induction of order-parameter components of distinct symmetry.

Holographic d-wave superconductors [PDF]
Journal of High Energy Physics, 2013 We construct top down models for holographic d-wave superfluids in which the order parameter is a charged spin two field in the bulk. Close to the transition temperature the condensed phase can be captured by a charged spin two field in an R-charged ...

Nonnegative/Binary matrix factorization with a D-Wave quantum annealer. [PDF]
PLoS One, 2018 D-Wave quantum annealers represent a novel computational architecture and have attracted significant interest, but have been used for few real-world computations. Machine learning has been identified as an area where quantum annealing may be useful. Here,

d-wave superconductivity in the Anderson lattice [PDF]
Journal of Magnetism and Magnetic Materials, 1987 We show, within a slave-boson 1/N expansion, that the U = ∞ lattice Anderson model is unstable to d-wave superconductivity. The pairing mechanism is slave-boson exchange between heavy quasiparticles. The model is extended to include the Coulomb pseudopotential. We discuss the pressure dependence of Tc in light of our theory.

Impurity Scattering in a d-Wave Superconductor [PDF]
Modern Physics Letters B, 1997 The influence of (non-magnetic and magnetic) impurities on the transition temperature of a d-wave superconductor is studied anew within the framework of BCS theory. Pairing interaction decreases linearly with the impurity concentration. Accordingly T c suppression is proportional to the (potential or exchange) scattering rate, 1/τ, due to impurities.

Supersymmetry and d-wave superconductivity [PDF]
Physical Review B, 2002 Motivated by a recent development in the field theory of the fractional quantum Hall effect, we propose a supersymmetric field theoretical model of quantum critical d-wave and (d+id)-wave superconductors. New concept is a composite particle with the supercharge which is formed by electron (hole) and supersymmetric collective configurations of spin and ...

Macroscopic quantum tunneling and quasiparticle-tunneling blockade effect in s-wave/d-wave hybrid junctions [PDF]
, 2007 We have theoretically investigated macroscopic quantum tunneling (MQT) and the influence of nodal quasiparticles and zero energy bound states (ZES) on MQT in s-wave/ d-wave hybrid Josephson junctions.

Conductance of d-wave superconductor/normal metal/d-wave superconductor junctions
Physical review letters, 2008 We develop a theory of the conductance of superconductor/normal metal/superconductor junctions in the case where the superconducting order parameter has d-wave symmetry. At low temperature the conductance is proportional to the square root of the inelastic electron relaxation time in the bulk of the superconductor.

Superflow in d-wave superconductors [PDF]
Superlattices and Microstructures, 1999 Superflow in a phenomenological tight-binding model for the superconducting state of some High-temperature superconductors is discussed thoroughly. The formalism used is explicitly gauge-invariant and currents are computed exactly within BCS theory, going therefore beyond linear response theory.
