Majorana fermions (particles that are their own antiparticle) may or may not exist in nature as elementary building blocks, but in condensed matter they can be constructed out of electron and hole excitations. What is needed is a superconductor to hide the charge difference and a topological (Berry) phase to eliminate the energy difference from zero-point motion. A pair of widely separated Majorana fermions, bound to magnetic or electrostatic defects, has non-Abelian exchange statistics. A… Expand
Majorana Fermions in Chiral Topological Superconductors
Majorana fermions were first proposed in the context of high energy physics by Ettore Majorana in 1937, just before his mysterious disappearance. Now, over 70 years later, signatures of condensedExpand
Majorana Fermions and Topology in Superconductors
Topological superconductors are novel classes of quantum condensed phases, characterized by topologically nontrivial structures of Cooper pairing states. On the surfaces of samples and in vortexExpand
Tunable Majorana fermion from Landau quantization in 2D topological superconductors
We study the generation of Majorana fermions in a two-dimensional topological superconductor placed in a transverse magnetic field B. A topological insulator/superconductor heterostructure and aExpand
Observation of Majorana fermions in ferromagnetic atomic chains on a superconductor
High-resolution spectroscopic imaging techniques show that the onset of superconductivity, which gaps the electronic density of states in the bulk of the Fe chains, is accompanied by the appearance of zero-energy end-states, providing strong evidence for the formation of a topological phase and edge-bound Majorana fermions in atomic chains.

Majorana fermions in magnetic chains
Abstract Majorana fermions have recently garnered a great attention outside the field of particle physics, in condensed matter physics. In contrast to their particle physics counterparts, MajoranaExpand
Signatures of Majorana Fermions in Hybrid Superconductor-Semiconductor Nanowire Devices
Electrical measurements on indium antimonide nanowires contacted with one normal (gold) and one superconducting (niobium titanium nitride) electrode support the hypothesis of Majorana fermions in Nanowires coupled to superconductors. Expand
A brief review on Majorana bound states in topological superconductors
Topological superconductivity has drawn much attention recently, and most interests are focused on the Majorana bound states existing at the edges of one-dimensional topological superconductors.Expand
Bosonization for fermions and parafermions
Parafermions are fractional excitations which can be regarded as generalizations of Majorana bound states, but in contrast to the latter they require electron-electron interactions. Compared toExpand
Signatures of tunable Majorana-fermion edge states
Chiral Majorana-fermion modes are shown to emerge as edge excitations in a superconductor–topological-insulator hybrid structure that is subject to a magnetic field. The velocity of this mode isExpand
Interacting Majorana Fermions.
Recent progress on the proposed experimental setups, analytical and numerical results on low-dimensional lattice mod- els, and the exactly solvable Sachdev-Ye-Kitaev model suggest that strongly correlated phases of matter with Majorana building blocks can exhibit many novel phenoms, such as emergent spacetime supersymmetry, topological order and the physics of black-holes, in condensed matter systems.

Electrically detected interferometry of Majorana fermions in a topological insulator.
This work shows how a pair of neutral Majorana fermions can be converted reversibly into a charged Dirac fermion, and enables electrical detection of a qubit by an interferometric measurement. Expand
Majorana bound states without vortices in topological superconductors with electrostatic defects.
This work identifies an alternative mechanism for the formation of Majorana bound states, akin to the way in which Shockley states are formed on metal surfaces: an electrostatic line defect can have a pair of Majoranas bound states at the end points. Expand
Avoidance of Majorana resonances in periodic topological superconductor-nanowire structures.
It is shown that presently realizable structures in experiments with tunable chemical potential lead to Majorana resonances, which are interesting in their own right, but do not manifest non-Abelian statistics. Expand
Controlling non-Abelian statistics of Majorana fermions in semiconductor nanowires
Under appropriate external conditions a semiconductor nanowire in proximity to an s-wave superconductor can be in a topological superconducting (TS) phase. This phase supports localized zero-energyExpand
Observing Majorana bound states of Josephson vortices in topological superconductors
The equations governing the dynamics of phase solitons (fluxons) in a Josephson junction in a topological superconductor are studied and it is shown that the fluxon will bind a localized zero energy Majorana mode and will consequently behave as a non-Abelian anyon. Expand

This work predicts a striking nonlocal phase-coherent electron transfer process by virtue of tunneling in and out of a pair of Majorana bound states in a superconductor-quantum-spin-Hall- insulator-magnetic-insulator hybrid system. Expand

In a variety of rare-earth-based compounds, singlet superconductivity coexists with helical magnetism. Here we demonstrate that surfaces of these systems should generically host a finite density ofExpand
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.
