Local density of states induced by anisotropic impurity scattering in a d-wave superconductor
P. Pisarski, G. Haran
We study a single impurity effect on the local density of states in a d-wave superconductor accounting for the momentum-dependent impurity potential. We show that the anisotropy of…
Effect of anisotropic impurity scattering on a density of states of a d-wave superconductor
A. Maciag, P. Pisarski, G. Haran
We discuss the effect of an anisotropic impurity potential on the critical temperature, local density of states in the vicinity of a single impurity, and the quasiparticle density…

We discuss the weak-coupling BCS theory of a superconductor with the impurities, accounting for their anisotropic momentum-dependent potential. The impurity scattering process is c…
The phase transition phenomena in anisotropic superconductors: effect of the orthorhombic crystal field and the potential impurity scattering
G. Haran, J. Taylor, A. D. S. Nagi
A combined effect of the orthorhombic crystal field and potential impurity scattering on several superconducting states of a tetragonal symmetry is studied within a weak-coupling m…
Comment on the anisotropic impurity scattering in superconductors
G. Haran, A. D. S. Nagi
We discuss a case of a strong anisotropic impurity scattering within the model introduced in our previous paper [Phys. Rev. B54, 15463 (1996)] and clarify our former statement abou…
Effects of Fermi Surface Anisotropy on Unconventional Superconductivity in UPt_3
G. Haran, P. J. Hirschfeld, M. Sigrist
We discuss the weak-coupling BCS theory of the heavy fermion superconductor UPt_3, accounting for that system's anisotropic, multisheeted Fermi surface by expanding the order param…
