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

What are topological phases of matter? First, they are phases of matter at zero temperature.
Second, they have a nonzero energy gap for the excitations above the ground state. Third …

Exotic states such as topological insulators, superconductors and quantum spin liquids are
often challenging or impossible to create in a single material,–. For example, it is unclear …

We provide a current perspective on the rapidly developing field of Majorana zero modes
(MZMs) in solid-state systems. We emphasise the theoretical prediction, experimental …

In non-centrosymmetric superconductors, where the crystal structure lacks a centre of
inversion, parity is no longer a good quantum number and an electronic antisymmetric spin …

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 …

This review elaborates pedagogically on the fundamental concept, basic theory, expected
properties, and materials realizations of topological superconductors. The relation between …

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 …

Topological insulators are new states of quantum matter which cannot be adiabatically
connected to conventional insulators and semiconductors. They are characterized by a full …
