Ettore Majorana (1906–1938) disappeared while traveling by ship from Palermo to Naples
in 1938. His fate has never been fully resolved and several articles have been written that …

The 1937 theoretical discovery of Majorana fermions—whose defining property is that they
are their own anti-particles—has since impacted diverse problems ranging from neutrino …

In this paper we present a new scenario where massive primordial black holes (PBHs) are
produced from the collapse of large curvature perturbations generated during a mild …

A major challenge in developing topological superconductors for implementing topological
quantum computing is their characterization and control. It has been proposed that ap-wave …

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 are novel classes of quantum condensed phases,
characterized by topologically nontrivial structures of Cooper pairing states. On the surfaces …

We propose an easy-to-build easy-to-detect scheme for realizing Majorana fermions at the
ends of a chain of magnetic atoms on the surface of a superconductor. Model calculations …

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

Recently, it has been suggested that topological superconductivity and Majorana end states
can be realized in a chain of magnetic impurities on the surface of an s-wave …

After a recent series of rapid and exciting developments, the long search for the Majorana
fermion—the elusive quantum entity at the border between particles and antiparticles—has …
