Unconventional superconductivity

Submission status
Submission deadline

Unconventional superconductors differ from conventional superconductors either with respect to the pairing mechanism (i.e. Cooper pairs are not bound together by phonon exchange) or the symmetry of the underlying order parameter (i.e. order parameter appears to be different from the usual singlet). High temperature superconductivity has driven the research in this field, and the first room temperature superconductor made of carbonaceous sulphur hydride was demonstrated in 2020 at 267 GPa. Reaching room temperature superconductivity at atmospheric pressure would be an achievement which could spark a revolution and herald a new technology era. Although unconventional superconductors have been studied for decades, there still remain many aspects that are not well understood and scientific research is focussed to shed light on these open questions.

This Collection reports the latest research in unconventional superconductors, welcoming experimental and theoretical studies to pave the way in the understanding of these phenomena.
