Nonlocal quasiparticle transport in normal-superconductor-normal (NSN) hybrid structures probes sub-gap states in the proximity region and is especially attractive in the context of Majorana research. Conductance measurement provides only partial information about nonlocal response composed from both electron-like and hole-like quasiparticle excitations. In this work, we show how a nonlocal shot noise measurement delivers a missing puzzle piece in NSN InAs nanowire-based devices. We demonstrate… 

Heat-Mode Excitation in a Proximity Superconductor

Mesoscopic superconductivity deals with various quasiparticle excitation modes, only one of them—the charge-mode—being directly accessible for conductance measurements due to the imbalance in

Nonlocal measurement of quasiparticle charge and energy relaxation in proximitized semiconductor nanowires using quantum dots

The lowest-energy excitations of superconductors do not carry an electric charge, as their wave function is equally electron-like and hole-like. This fundamental property is not easy to study in

Nonlocal conductance and the detection of Majorana zero modes: Insights from von Neumann entropy

The topological origin of the zero bias conductance signatures obtained via conductance spectroscopy in topological superconductor hybrid systems is a much contended issue. Recently, nonlocal

Probing the topological character of superconductors via nonlocal Hanbury Brown and Twiss correlations

Superconductors can be classified as topological or not based on whether time-reversal symmetry (TRS), chiral symmetry, and particle-hole symmetry are preserved or not. Further, topological

Andreev rectifier: A nonlocal conductance signature of topological phase transitions

The proximity effect in hybrid superconductor-semiconductor structures, crucial for realizing Majorana edge modes, is complicated to control due to its dependence on many unknown microscopic

Non-Majorana states yield nearly quantized conductance in superconductor-semiconductor nanowire devices

Conductance at zero source-drain voltage bias in InSb nanowire/NbTiN superconductor devices exhibits peaks that are close to a quantized value of $2e^2/h$. The nearly quantized resonances evolve in

Closing of the induced gap in a hybrid superconductor-semiconductor nanowire

Hybrid superconductor-semiconductor nanowires are predicted to undergo a field-induced phase transition from a trivial to a topological superconductor, marked by the closure and re-opening of the

Three-terminal nonlocal conductance in Majorana nanowires: Distinguishing topological and trivial in realistic systems with disorder and inhomogeneous potential

We develop a theory for the three-terminal nonlocal conductance in Majorana nanowires as existing in the superconductor-semiconductor hybrid structures in the presence of superconducting proximity,

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.

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.

Detection of doubled shot noise in short normal-metal/ superconductor junctions

A shot-noise experiment using a short diffusive normal-metal superconductor contact is reported, in which the predicted noise behaviour for double charges is confirmed and measurements establish that phase coherence is not required to observe the effect.

Nonlocal Conductance Spectroscopy of Andreev Bound States: Symmetry Relations and BCS Charges.

It is found that the nonlocal elements of the conductance matrix are directly related to the local BCS charges of the bound states close to the normal probes and it is shown how the BCS charge of overlapping Majorana bound states can be extracted from experiments.
