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 …

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 …

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 …

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 …

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

Experimental and theoretical progress toward quantum computation with spins in quantum
dots (QDs) is reviewed, with particular focus on QDs formed in GaAs heterostructures, on …

We study a one-dimensional interacting electronic liquid coupled to a 1D array of classical
magnetic moments and to a superconductor. We show that at low energy and temperature …

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 …

We study multiband semiconducting nanowires proximity coupled with an s-wave
superconductor and calculate the topological phase diagram as a function of the chemical …

We consider the problem of quasiparticle poisoning in a nanowire-based realization of a
Majorana qubit, where a spin-orbit-coupled semiconducting wire is placed on top of a (bulk) …
