The order parameter of bulk two-dimensional superconductors is classified as nodal, if it vanishes for a direction in momentum space, or gapful if it does not. Each class can be topologically nontrivial if Andreev bound states are formed at the edges of the superconductor. Non-magnetic impurities in the superconductor affect the formation of Andreev bound states and can drastically change the tunneling spectra for small voltages. Here, we investigate the mean current and its fluctuations for…

Finite frequency noise in a normal metal–topological superconductor junction

A topological superconductor nanowire bears a Majorana bound state at each of its ends, leading to unique transport properties. As a way to probe these, we study the finite frequency noise of a

Quasiclassical circuit theory of contiguous disordered multiband superconductors

We consider a general problem of a Josephson contact between two multiband superconductors with coexisting superconducting and magnetic phases. As a particular example, we use the quasiclassical

Subgap states in two-dimensional spectroscopy of graphene-based superconducting hybrid junctions

Several recent works have predicted that unconventional and topological superconductivity can arise in graphene, either intrinsically or by proximity effect. Then, the analysis of the spectroscopic

We theoretically describe a thermoelectric effect that is entirely due to Andreev processes involving the formation of Cooper pairs through the coupling of electrons and holes. The Andreev

Impurity-induced states in conventional and unconventional superconductors

We review recent developments in our understanding of how impurities influence the electronic states in the bulk of superconductors. Our focus is on the quasi-localized states in the vicinity of

4π-periodic Josephson supercurrent in HgTe-based topological Josephson junctions

The observation of an anomalous response to rf irradiation in a Josephson junction made of a HgTe weak link is reported, understood as due to a 4π-periodic contribution to the supercurrent, and its amplitude is compatible with the expected contribution of a gapless Andreev doublet.

Tunnelling effects on surface bound states in unconventional superconductors

Recent studies on high-Tc superconductors have aroused new interest in tunnelling effects in unconventional superconductors. Unlike in conventional s-wave superconductors, the d-wave pairing state in

A new experiment is proposed: Andreev scattering, i.e., scattering of low-energy normal quasiparticles off the spatially varying order parameter when the qu asiparticles approach a normal-metal--superconductor interface from the normal side.

Current fluctuations in mesoscopic systems with Andreev scattering.

A scattering theory approach is used to study the zero-frequency current fluctuations of the normal terminals of a phase-coherent mesoscopic structure with a superconducting region and derives an approximate formula valid in the small bias limit.

Andreev Reflection in an s-Type Superconductor Proximized 3D Topological Insulator.

This work identifies the Andreev reflection (AR) regime, which gives rise to the effective charge doubling in shot noise measurements, and suggests that this effect is related to a finite thermal conduction of the proximized, superconducting TI owing to a residual density of states at low energies.

The current theory and experimental results on chiral superconductors are discussed, focusing on two of the best-studied systems, Sr2RuO4, which is thought to be a chiral triplet p-wave superconductor, and UPt3, which has two low-temperature superconducting phases (in zero magnetic field), the lower of which is believed to be chiral doublet f-wave.
