A possible sighting of Majorana states Nearly 80 years ago, the Italian physicist Ettore Majorana proposed the existence of an unusual type of particle that is its own antiparticle, the so-called Majorana fermion. The search for a free Majorana fermion has so far been unsuccessful, but bound Majorana-like collective excitations may exist in certain exotic superconductors. Nadj-Perge et al. created such a topological superconductor by depositing iron atoms onto the surface of superconducting… Expand

    Chiral Majorana fermion modes in a quantum anomalous Hall insulator–superconductor structure
    TLDR
    Transport measurements that suggest the existence of one-dimensional chiral Majorana fermion modes in the hybrid system of a quantum anomalous Hall insulator thin film coupled with a superconductor are reported. Expand
    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, Majorana… Expand
    Signature of a pair of Majorana zero modes in superconducting gold surface states
    TLDR
    Using scanning tunneling microscope to probe EuS islands grown on top of gold nanowires, two well-separated zero-bias tunneling conductance peaks aligned along the direction of the applied magnetic field are observed, as expected for a pair of Majorana zero modes. 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 condensed… Expand
    Majorana bound states in a superconducting Rashba nanowire deposited on an antiferromagnetic surface
    Theoretical studies have shown that Majorana bound states can be induced at the ends of a one dimensional wire, a phenomenon possible due to the interplay between s-wave superconductivity, spin-orbit… Expand
    Evidence for dispersing 1D Majorana channels in an iron-based superconductor
    TLDR
    Scanning tunneling spectroscopy suggests a propagating Majorana state along a domain wall on the surface of FeSe0.45Te0.55, which is consistent with the observation of dispersing Majorana states at a π-phase shift DW in a proximitized topological material. Expand
    Majorana bound states in a superconducting Rashba nanowire in the presence of antiferromagnetic order
    Theoretical studies have shown that Majorana bound states can be induced at the ends of a one-dimensional wire, a phenomenon possible due to the interplay between $s$-wave superconductivity,… Expand
    Majorana fermions in ferromagnetic chains on the surface of bulk spin-orbit coupled s-wave superconductors
    TLDR
    It is shown that a ferromagnetic chain deposited on the surface of a spin-orbit coupled s-wave superconductor generically supports zero-energy topological MF excitations near the two ends of the chain with minimal fine-tuning. Expand
    Observation of topological superconductivity on the surface of an iron-based superconductor
    TLDR
    The researchers found that the surface of the iron superconductor FeTe0.55Se0.45 satisfies the required conditions for topological superconductivity, providing a simple and possibly high-temperature platform for realizing Majorana states. Expand
    Evidence for Majorana bound states in an iron-based superconductor
    TLDR
    A sharp zero-bias peak inside a vortex core that does not split when moving away from the vortex center is observed, consistent with the tunneling to a nearly pure MBS, separated from nontopological bound states. Expand

    This review paper highlights recent advances in the condensed matter search for Majorana that have led many in the field to believe that this quest may soon bear fruit and discusses the most remarkable properties of condensed matter Majorana fermions-the non-Abelian exchange statistics that they generate and their associated potential for quantum computation.

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

    Correlations between Majorana fermions through a superconductor.
    TLDR
    It is demonstrated that besides the well-known direct-overlap-induced energy splitting, the two MF bound states may hybridize via elastic tunneling processes through virtual quasiparticle states in the SC, giving rise to an additional energy splitting between MF states from the same as well as from different wires.
