چکیده
F i g . 1 . ( a) Proximitised Rashba nanowire of finite length with gate-tunable Fermi energy and under a parallel Zeeman field Vz. (b) Bound charges ρb arise in the dielectric surroundings, which interact with free charges in the nanowire. (c,d) Noninteracting and interacting spectra of the nanowire. Extended zero modes (in red) in (d) are the result of the interaction-induced pinning, discussed in this work, of Majoranas at zero energy around parity crossings.

Zero-energy Pinning from Interactions in Majorana Nanowires,Transport spectroscopy of NS nanowire junctions with Majorana fermions
We investigate transport though normal-superconductor nanowire junctions in the presence of spin-orbit coupling and magnetic field. As the Zeeman field crosses the critical bulk value Bc of the topological transition, a Majorana bound state (MBS) is formed, giving rise to a sharp zero-bias anomaly (ZBA) in the tunneling differential conductance. We identify novel features beyond this picture in...
متن کاملInteracting topological phases in multiband nanowires
We show that semiconductor nanowires coupled to an s-wave superconductor provide a playground to study effects of interactions between different topological superconducting phases supporting Majorana zero-energy modes. We consider quasi-one dimensional system where the topological phases emerge from different transverse subbands in the nanowire. In a certain parameter space, we show that there ...
متن کاملElectromagnetic absorption of quasi-1D Majorana nanowires
We calculate the electromagnetic absorption cross section of long and narrow nanowires, in the so-called quasi-1D limit. We consider only two transverse bands and compute the dipole absorption cross section taking into account quasiparticle transitions from negative to positive energy eigenstates of the Bogoliubov-de Gennes Hamiltonian. The presence of the zero energy (Majorana) state manifests...
متن کاملNear-zero-energy end states in topologically trivial spin-orbit coupled superconducting nanowires with a smooth confinement
A one-dimensional spin-orbit coupled nanowire with proximity-induced pairing from a nearby s-wave superconductor may be in a topological nontrivial state, in which it has a zero-energy Majorana bound state at each end. We find that the topological trivial phase may have fermionic end states with an exponentially small energy, if the confinement potential at the wire’s ends is smooth. The possib...
متن کاملMajorana bound states from exceptional points in non-topological superconductors.
Recent experimental efforts towards the detection of Majorana bound states have focused on creating the conditions for topological superconductivity. Here we demonstrate an alternative route, which achieves fully localised zero-energy Majorana bound states when a topologically trivial superconductor is strongly coupled to a helical normal region. Such a junction can be experimentally realised b...
