We study multiband semiconducting nanowires proximity coupled with an $s$-wave superconductor and calculate the topological phase diagram as a function of the chemical potential and magnetic field. The nontrivial topological state corresponds to a superconducting phase supporting an odd number of pairs of Majorana modes localized at the ends of the wire, whereas the nontopological state corresponds to a superconducting phase with no Majoranas or with an even number of pairs of Majorana modes… 
Stability of Majorana Fermions in Proximity-Coupled Topological Insulator Nanowires
It has been shown previously that a finite-length topological insulator nanowire, proximity-coupled to an ordinary bulk s-wave superconductor and subject to a longitudinal applied magnetic field,

TLDR
This review provides an update on the current status of the search for Majorana fermions in semiconductor nanowires by focusing on the recent developments, in particular the period following the first reports of experimental signatures consistent with the realization of Majorana bound states in semiconducting nanowire-superconductor hybrid structures.
Majorana and non-Majorana modes in a nanowire in partially proximity to a superconductor
We investigate the Majorana and non-Majorana modes in a nanowire in partial proximity to a superconductor, in which the gapped superconductor will play different roles in different topological
Properties and Transport Characteristics of Majorana Fermions in Nanowires
Majorana fermions are quasiparticle excitations which are features of a two-dimensional quantum system in a so-called topological phase. Majorana fermions are non-Abelian anyons and the system
Robustness of topological order in semiconductor–superconductor nanowires in the Coulomb blockade regime
Semiconductor?superconductor hybrid systems are promising candidates for the realization of Majorana fermions and topological order, i.e. topologically protected degeneracies, in solid state devices.
Topological superconductivity in a phase-controlled Josephson junction
TLDR
This work establishes this system as a promising platform for realizing topological superconductivity and for creating and manipulating Majorana modes and probing topologicalsuperconducting phases in two-dimensional systems.
Majorana Kramers pairs in Rashba double nanowires with interactions and disorder
We analyze the effects of electron-electron interactions and disorder on a Rashba double-nanowire setup coupled to an s-wave superconductor, which has been recently proposed as a versatile platform
Flux-induced topological superconductivity in full-shell nanowires
TLDR
Evidence is presented that is consistent with the emergence of Majorana zero modes in this system, and further experimental evidence that the zero-energy states are delocalized at wire ends by investigating Coulomb blockade conductance peaks in full-shell wire islands of various lengths.
Robust topological superconductivity in weakly coupled nanowire-superconductor hybrid structures
We investigate the role of the coupling between a spin-orbit coupled semiconductor nanowire and a conventional s -wave superconductor on the emergence of the topological superconducting phase with
Effects of the electrostatic environment on superlattice Majorana nanowires
Finding ways of creating, measuring and manipulating Majorana bound states (MBSs) in superconducting-semiconducting nanowires is a highly pursued goal in condensed matter physics. It was recently
