Frustration in magnetic materials arising from competing exchange interactions can prevent
the system from adopting long-range magnetic order and can instead lead to a diverse …

A wide range of materials, like d-wave superconductors, graphene, and topological
insulators, share a fundamental similarity: their low-energy fermionic excitations behave as …

We perform a theoretical examination of the local electronic structure in the recently
discovered bilayer high-temperature superconductor La 3 Ni 2 O 7. Our method begins with …

We propose an easy-to-build easy-to-detect scheme for realizing Majorana fermions at the
ends of a chain of magnetic atoms on the surface of a superconductor. Model calculations …

A recent experiment [Nadj-Perge et al., Science 346, 602 (2014)] provides evidence for
Majorana zero modes in iron (Fe) chains on the superconducting Pb (110) surface. Here, we …

Emergent electronic phenomena in iron-based superconductors have been at the forefront
of condensed matter physics for more than a decade. Much has been learned about the …
