The physics of quantum materials is dictated by many-body interactions and mathematical
concepts such as symmetry and topology that have transformed our understanding of matter …

Superconductivity is a remarkably widespread phenomenon that is observed in most metals
cooled to very low temperatures. The ubiquity of such conventional superconductors, and …

The search for Majorana bound states (MBSs) has been fueled by the prospect of using their
non-Abelian statistics for robust quantum computation. Two-dimensional superconducting …

Majorana quasiparticles in condensed matter are important for topological quantum
computing,–, but remain elusive. Vortex cores of topological superconductors may …

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 …

Topological materials and unconventional iron-based superconductors are both important
areas of study but, to date, relatively little overlap has been identified between these two …

Bardeen-Cooper-Schrieffer (BCS) superfluidity and Bose-Einstein condensation (BEC) are
the two extreme limits of the ground state of the paired fermion systems. We report crossover …

Abstract The BCS-BEC (Bardeen-Cooper-Schrieffer–Bose-Einstein-condensate) crossover
from strongly overlapping Cooper pairs to non-overlapping composite bosons in the strong …

Vortices in topological superconductors may host Majorana zero modes (MZMs), which have
been proposed as the building blocks of fault-tolerant topological quantum computers …

High-temperature superconductivity and a wide variety of exotic superconducting states
discovered in FeSe-based materials have been at the frontier of research on condensed …
