Scope

For a long time, all known forms of superconductivity corresponded to electron pairing, described by a single-component order parameter. The possibility of forming a multicomponent superconducting state with an order parameter that spontaneously breaks more than one symmetry has been theoretically considered for a long time, but only recently have multiple compelling candidates been identified in experiments.   Multicomponent topological superconductors are sought after for their potential applications in quantum information processing. Furthermore, Recent experiments have reported evidence for   new states of matter: electron quadrupling condensates that arise in systems that break multiple symmetries. We aim to bring together leading theorists and experimentalists to shed light on multicomponent superconductivity.
