We study the effects of strong coupling between a superconductor and a semiconductor nanowire on the creation of the Majorana bound states, when the quasiparticle dwell time in the normal part of the nanowire is much shorter than the inverse superconducting gap. This "short-junction" limit is relevant for the recent experiments using the epitaxially grown aluminum characterized by a transparent interface with the semiconductor and a small superconducting gap. We find that the small… 

Durability of the superconducting gap in Majorana nanowires under orbital effects of a magnetic field

We analyze the superconducting gap in semiconductor/superconductor nanowires under orbital effects of a magnetic field in the weak- and strong-hybridization regimes using an universal procedure that

We consider a nanowire with the s-wave superconducting order induced as a result of the proximity effect in the presence of the Zeeman field and the Rashba interaction. For a small superconducting

Renormalization of the Majorana bound state decay length in a perpendicular magnetic field

Orbital effects of a magnetic field in a proximitized semiconductor nanowire are studied in the context of the spatial extent of Majorana bound states. We develop analytical model that explains the

Effects of Gate-Induced Electric Fields on Semiconductor Majorana Nanowires

We study the effect of gate-induced electric fields on the properties of semiconductor-superconductor hybrid nanowires which represent a promising platform for realizing topological superconductivity

Tunneling conductance in semiconductor-superconductor hybrid structures

We study the differential conductance for charge tunneling into a semiconductor wire--superconductor hybrid structure, which is actively investigated as a possible scheme for realizing topological

Renormalization effects in spin-polarized metallic wires proximitized by a superconductor: A scattering approach

Spin-polarized normal-metal wires coupled to a superconductor can host Majorana states at their ends. These decay into the bulk and are protected by a minigap in the spectrum. Previous studies have

Disorder-induced suppression of the zero-bias conductance peak splitting in topological superconducting nanowires

TLDR
It is found that the disorder can effectively lead to a reduction in the conductance peak spacings and significantly suppress the peak height, particularly for a longer nanowire, which could be reproduced by weak disorder for a finite Majorana energy splitting.

Zeeman and spin-orbit effects in the Andreev spectra of nanowire junctions

We study the energy spectrum and the electromagnetic response of Andreev bound states in short Josephson junctions made of semiconducting nanowires. We focus on the joint effect of Zeeman and

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
