Title: Majorana quasiparticles in condensed matter,
Abstract: 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 brief perspective of where we are with strong focus
on artificial implementations of one-dimensional topological superconductivity.
After a self-contained introduction and some technical parts, an overview of
the current experimental status is given and some of the most successful
experiments of the last few years are discussed in detail. These include the
novel generation of ballistic InSb nanowire devices, epitaxial Al-InAs
nanowires and Majorana boxes, high frequency experiments with proximitized
quantum spin Hall insulators realised in HgTe quantum wells and recent
experiments on ferromagnetic atomic chains on top of superconducting surfaces.
