Majorana quasiparticles of inhomogeneous Rashba chain

  title={Majorana quasiparticles of inhomogeneous Rashba chain},
  author={Maciej M Maśka and Anna Gorczyca-Goraj and Jakub Tworzydło and Tadeusz Domański},
We investigate the inhomogeneous Rashba chain coupled to a superconducting substrate, hosting the Majorana quasiparticles near its edges. We discuss its subgap spectrum and study how robust are the zero-energy quasiparticles against the diagonal and off-diagonal disorder. Studying the Z2 topological invariant we show that disorder induced transition from the topologically non-trivial to trivial phases is manifested by characteristic features in the spatially-resolved quasiparticle spectrum at… 

Polarization of the Majorana quasiparticles in the Rashba chain

We demonstrate that the selective equal–spin Andreev reflection (SESAR) spectroscopy can be used in STM experiments to distinguish the zero–energy Majorana quasiparticles from the ordinary fermionic

Topological isoconductance signatures in Majorana nanowires

If highly nonlocal and nonoverlapping MBSs are formed in the system, the zero-bias Andreev conductance through the dot exhibits characteristic isoconductance profiles with the shape depending on the spin asymmetry of the coupling between the dot and the topological superconductor.

How to measure a Majorana: The Majorana polarization of a topological planar Josephson junction

We analyze the topological superconductivity, and investigate the spectroscopic properties manifested by zero-energy modes, induced in a metallic strip embedded into a Josephson-type junction.

Low dimensional structures in the non-trivial topological phase can host the in-gap Majorana bound states identified experimentally as zero-bias peaks in differential conductance. Theoretical methods

Controlling the bound states in a quantum-dot hybrid nanowire

Recent experiments using the quantum dot coupled to the topological superconducting nanowire [M.T. Deng et al., Science 354, 1557 (2016)}] revealed that zero-energy bound state coalesces from the

Identification of Majorana Modes in Interacting Systems by Local Integrals of Motion.

This work determines the regime for which the information stored in the Majorana correlators is also retained for arbitrarily long times at high temperatures, and shows that it is included in the regime with topologically protected soft Majorana modes, but in some cases is significantly smaller.

Search for Majorana fermions in multiband semiconducting nanowires.

The key finding is that multiband occupancy not only lifts the stringent constraint of one-dimensionality but also allows one to have higher carrier density in the nanowire, and as such multisubband nanowires are better suited for observing the Majorana particle.

Majorana fermions in superconducting 1D systems having periodic, quasiperiodic, and disordered potentials.

A topological invariant derived from the equations of motion for Majorana modes is defined and employed to characterize the phase diagram for simple periodic structures and its general result is a relation between the normal state localization length.

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

Disorder-induced topological transitions in multichannel Majorana wires

In this work, we investigate the effect of disorder on the topological properties of multichannel superconductor nanowires. While the standard expectation is that the spectral gap is closed and

Majorana fermions and a topological phase transition in semiconductor-superconductor heterostructures.

The measurement of the supercurrent through the junction allows one to discern topologically distinct phases and observe a topological phase transition by simply changing the in-plane magnetic field or the gate voltage, which will be a direct demonstration of the existence of Majorana particles.

We consider Majorana fermions (MFs) in quasi-one-dimensional nanowire systems containing normal and superconducting sections where the topological phase based on Rashba spin-orbit interaction can be

Strong localization of Majorana end States in chains of magnetic adatoms.

This work considers a linear chain of Anderson impurities on a superconductor as a minimal model and treats it largely analytically within mean-field theory, exploring the phase diagram, the subgap excitation spectrum, and the Majorana wave functions.

Probability distribution of Majorana end-state energies in disordered wires.

It is shown that the probability distribution of ε(0) is log normal in the limit of large L, whereas the distribution of the lowest-lying bulk energy levelε(1) has an algebraic tail at small δ(1), which has implications for the speed at which a topological quantum computer can be operated.

ac Josephson effect in finite-length nanowire junctions with Majorana modes.

The ac Josephson transients are protected against decay by quasiparticle poisoning as a consequence of the quantum Zeno effect, which fixes the parity of Majorana qubits, and may be effectively used to detect MBS.
