Effect of thermal fluctuations in topological p-wave superconductors

We study the effect of thermal fluctuations on the topological stability of chiral p-wave superconductors. We consider two models of superconductors: spinless and spinful with a focus on topological properties and Majorana zero-energy modes. We show that proliferation of vortex-antivortex pairs above the Kosterlitz-Thouless temperature TKT drives the transition from a thermal Quantum Hall insul...

On Distinguishing d-wave from Highly Anisotropic s-wave Superconductors

Systematic impurity doping in the Cu-O plane of the hole-doped cuprate superconductors may allow one to decide between unconventional (”d-wave”) and anisotropic conventional (”s-wave”) states as possible candidates for the order parameter in these materials. We show that potential scattering of any strength always increases the gap minima of such s-wave states, leading to activated behavior in ...

On Possibility of Realization of d- or p-Wave Symmetry States in Anisotropic Superconductors

We consider a model of high-Tc superconductors with an anisotropic boson-mediated pairing mechanism corresponding to the nearest-neighbor interactions, and the one-particle dispersion relation characterized by 2D Fermi surface nesting. Based upon the tight-binding or t−J approaches with half-filling we show that the effective pairing potential coefficients and the dispersion relation, which can...

Chiral Correction to the Spin Fluctuation Feedback in two-dimensional p-wave Superconductors

– We consider the stability of the superconducting phase for spin-triplet p-wave pairing in a quasi-two-dimensional system. We show that in the absence of spin-orbit coupling there is a chiral contribution to spin fluctuation feedback which is related to spin quantum Hall effect in a chiral superconducting phase. We show that this mechanism supports the stability of a chiral p-wave state. Coope...

Theoretical Prediction of the Fractional ac Josephson Effect in p- and d-Wave Superconductors

For certain orientations of Josephson junctions between two px-wave or two d-wave superconductors, the subgap Andreev states produce a 4π-periodic relation between the Josephson current I and the phase difference φ: I ∝ sin(φ/2). Consequently, the ac Josephson current has the fractional frequency eV/~, where V is the dc voltage. In the tunneling limit, the Josephson current is proportional to t...
