Among the major avenues that are being pursued for realizing quantum bits, the Majorana-
based approach has been the most recent to be launched. It attempts to realize qubits that …

Inhomogeneous superconductors can host electronic excitations, known as Andreev bound
states (ABSs), below the superconducting energy gap. With the advent of topological …

In the space of less than one decade, the search for Majorana quasiparticles in condensed
matter has become one of the hottest topics in physics. The aim of this review is to provide a …

Majorana bound states are quasiparticle excitations localized at the boundaries of a
topologically nontrivial superconductor. They are zero-energy, charge-neutral, particle–hole …

In bulk superconductors or Josephson junctions formed in materials with spin-orbit
interaction, the critical current can depend on the direction of current flow or of applied …

We study the key features of the Josephson transport through a curved semiconducting
nanowire. Based on numerical simulations and analytical estimates within the framework of …

The protection against backscattering provided by topology is a striking property. In two-
dimensional insulators, a consequence of this topological protection is the ballistic nature of …

Although signatures of superconductivity in Dirac semimetals have been reported, for
instance by applying pressure or using point contacts, our understanding of the topological …

Abstract Majorana fermions are spin-1/2 neutral particles that are their own antiparticles and
were initially predicted by Ettore Majorana in particle physics but their observation still …

We consider phase-biased Josephson junctions with spin-orbit coupling under external
magnetic fields and study the emergence of the Josephson diode effect in the presence of …
