The quantum Hall (QH) effect, quantized Hall resistance combined with zero longitudinal
resistance, is the characteristic experimental fingerprint of Chern insulators—topologically …

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 …

We present measurements and simulations of semiconductor-superconductor
heterostructure devices that are consistent with the observation of topological …

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

Realizing topological superconductivity and Majorana zero modes in the laboratory is a
major goal in condensed-matter physics. In this Review, we survey the current status of this …

Topological superconductivity can emerge from the combination of conventional
superconductivity in a metal and strong spin–orbit coupling in a semiconductor when they …

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 …

Semiconductor nanowires with proximity-induced superconductivity are leading contenders
