چکیده

We present a theory for the differential shot noise, $dS/dV$, as measured via shot-noise scanning tunneling spectroscopy, and conductance, $dI/dV$, into Majorana zero modes (MZMs) in putative topological superconductor ${\mathrm{FeSe}}_{0.45}{\mathrm{Te}}_{0.55}$. demonstrate that chiral edge near domain walls, well MZMs localized vortex cores at end of defect lines, $dS/dV$ vanishes whenever $dI/dV$ reaches quantized value being equal to quantum conductance. These results are independent particular orbital path, thus establishing vanishing concomitant with universal signatures two-dimensional superconductors, irrespective material's specific complex electronic band structure.

Shot noise in negative-differential-conductance devices

Shot noise: Fluctuations of the current flowing through a device that result from the discreteness of the charge carrier. Shot noise provides information on the charge carriers and the transport mechanism in the device. The shot noise measurements in semiconductor heterostructure devices shed light on how the devices operate, beyond information provided by the electrical conductance. The shot n...

Negative differential conductance and super-Poissonian shot noise in single-molecule magnet junctions

Molecular spintroinic device based on a single-molecule magnet is one of the ultimate goals of semiconductor nanofabrication technologies. It is thus necessary to understand the electron transport properties of a single-molecule magnet junction. Here we study the negative differential conductance and super-Poissonian shot noise properties of electron transport through a single-molecule magnet w...

Statistics of Conductance and Shot-Noise Power for Chaotic Cavities

We report on an analytical study of the statistics of conductance, g, and shot-noise power, p, for a chaotic cavity with arbitrary numbers N1,2 of channels in two leads and symmetry parameter β = 1, 2, 4. With the theory of Selberg’s integral the first four cumulants of g and first two cumulants of p are calculated explicitly. We give analytical expressions for the conductance and shot-noise di...
