Quasiparticle resonant states induced by a unitary impurity in a d-wave superconductor
The quasiparticle resonant states around a single nonmagnetic impurity with unitary scattering in a d-wave superconductor is studied by solving the Bogoliubov–de Gennes equations based on a t-J model. Both the spatial variation of the order parameter and the local density of states ~LDOS! around the impurity have been investigated. We find that ~i! a particle-hole symmetric system has a single ...
متن کاملImpurity in a d-wave superconductor: Kondo effect and STM spectra.
We present a theory for recent STM studies of Zn impurities in the superconductor Bi2Sr2CaCu2O8+delta, using insights from NMR experiments which show that there is a net S = 1/2 moment on the Cu ions near the Zn. We argue that the Kondo spin dynamics of this moment is the origin of the low bias peak in the differential conductance, rather than a resonance in a purely potential scattering model....
متن کاملInfluence of impurity scattering on tunneling conductance in normal metal – d - wave superconductor junctions
Tunneling conductance spectra between a normal metal / d-wave superconductor junction under the presence of bulk impurities in the superconductor are studied. The quasiclassical theory has been applied to calculate the spatial variation of the pair potential and the effect of impurity scattering has been introduced by t-matrix approximation. The magnitude of a subdominant s-wave component at th...
متن کاملDensity of States of a d-wave Superconductor in the Presence of Strong Impurity Scatterers: a Non Perturbative Result
We present a method to compute the density of states induced by N non magnetic impurities in a d-wave superconductor, in the unitary limit of very strong scatering centers. For frequencies very small as compared to the su-perconducting gap (ω ≪ ∆ 0) the additional density of states has the leading divergence δρ(ω) ≃ n i / |2ω| ln 2 |ω/∆ 0 | + (π/2) 2. This result is non per-turbative.
متن کاملFundamental properties of a vortex in a d-wave superconductor
The vortex core structure in a d-wave superconductor is analyzed on the basis of the quasi-classical Eilenberger theory beyond the Ginzburg-Landau framework. The current and magnetic eld distributions around an isolated vortex break circular symmetry seen in s-wave pairing and show four-fold symmetry, re BLOCKINecting the internal degrees of freedom in d-wave pairing, i.e. ^ k 2 x 0 ^ k 2 y in ...
