Spin–orbit coupling induces a unique form of Zeeman interaction in momentum space in
materials that lack inversion symmetry: the electron's spin is locked on an effective magnetic …

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 …

Majorana bound states constitute one of the simplest examples of emergent non-Abelian
excitations in condensed matter physics. A toy model proposed by Kitaev shows that such …

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 …

The possibility of engineering artificial Kitaev chains in arrays of quantum dots coupled via
narrow superconducting regions has emerged as an attractive way to overcome the disorder …

We propose heterostructures that realize first and second order topological
superconductivity with vanishing net magnetization by utilizing altermagnetism. Such …

Traditionally, the primary field, where curvature has been at the heart of research, is the
theory of general relativity. In recent studies, however, the impact of curvilinear geometry …

Topological superconductors are an essential component for topologically protected
quantum computation and information processing. Although signatures of topological …

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