One of the most exciting areas of research in quantum condensed matter physics is the push
to create topologically protected qubits using non-Abelian anyons. The focus of these efforts …

Localized or propagating Majorana boundary modes are the key feature of topological
superconductors. They are rare in naturally occurring compounds, but the tailored …

Magnetic adatom chains on surfaces constitute fascinating quantum spin systems.
Superconducting substrates suppress interactions with bulk electronic excitations but couple …

The scattering of superconducting pairs by magnetic impurities on a superconducting
surface leads to pairs of sharp in-gap resonances known as Yu-Shiba-Rusinov (YSR) bound …

Spin chains proximitized with superconducting condensates have emerged as one of the
most promising platforms for the realization of Majorana modes. Here, we craft diluted spin …

Coupling individual atoms fundamentally changes the state of matter: electrons bound to
atomic cores become delocalized turning an insulating state to a metallic one. A chain of …

Magnetic adatoms on superconductors give rise to Yu-Shiba-Rusinov (YSR) states that hold
considerable interest for the design of topological superconductivity. Here, we show that …

We present an exactly solvable effective model of a double quantum dot coupled to
superconducting leads. This model is a generalization of the well-known superconducting …

Magnetic impurities in s-wave superconductors lead to spin-polarized Yu-Shiba-Rusinov
(YSR) in-gap states. Chains of magnetic impurities offer one of the most viable routes for the …

Magnetic adatoms on a superconducting substrate undergo a quantum phase transition as
their exchange coupling to the conduction electrons increases. For quantum spins, this …
