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 …

During the past 15 years a new field has emerged, which combines superconductivity and
spintronics, with the goal to pave a way for new types of devices for applications combining …

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 …

Topological superconductors that support Majorana fermions have been predicted when
one-dimensional semiconducting wires are coupled to a superconductor,,. Such excitations …

The Josephson effect describes the generic appearance of a supercurrent in a weak link
between two superconductors. Its exact physical nature deeply influences the properties of …

In recent years, Majorana physics has attracted considerable attention because of exotic
new phenomena and its prospects for fault-tolerant topological quantum computation. To …

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

We propose a tune-free scheme to realize Kramers pairs of Majorana bound states in
recently discovered higher-order topological insulators (HOTIs). We show that, by bringing …
