The meeting aims to bring together in a fully online format scientists working on topological aspects in heavy fermion-like materials, including topological Kondo insulators, quantum critical phenomena and unconventional superconductivity. The workshop is organized mostly by American and European scientists, the latter including those interested in the COST Action superqumap. But it is completely open to any contribution to the field.

Our current knowledge of the nature of unconventional superconductivity in heavy fermion-like materials and its relationship to topological and Weyl superconductivity is fairly limited. A prime example is the superconducting state in UTe2 triggering a flurry of activity in the past few years. This U based layered material presents amazing superconducting properties and challenges our hitherto understanding of superconductivity in f-electron materials. In a short amount of time, it has grown to be one of the most remarkable heavy fermion superconductors. It is of course not the only compound which has attracted recent attention by scientists working on topological superconductivity. The inherent strong spin orbit coupling in f-electron materials and the unconventional superconducting state make heavy fermion superconductors a prime testing ground for research and to provide information useful for many other superconducting systems.
The advances in unconventional superconductivity go together with technical developments in crystal growth, new spectroscopies, high pressures, computational capabilities and theory. The goal of this workshop is to bring together young researchers in the field of heavy fermion superconductivity and foster collaborations to address the most pressing needs more efficiently by combining knowledge and techniques available at different places. The workshop aims to bring together scientists that are geographically far from each other, but scientifically very close. Work in progress as well as new developments are explicitly welcome.
Topics will include:

  • Superconducting pairing symmetries in heavy fermions.
  • Topological properties of heavy fermions.
  • Superconductivity in d and f electron systems.
  • Quantum criticality and Cooper pairing.
  • Advances in spectroscopic and imaging techniques.
  • Experiments in large scale facilities.
  • Phase diagrams.
  • High pressure, high magnetic fields.
  • Josephson coupling, vortex lattices in unconventional superconductors.

Participants who register in e-cost will be informed about future in-person and online activities of the Action. You might register using this link Please write to as soon as you have registered and let us know which email account did you use. In case you already registered in e-cost in the past but you never participated in the activities of our Action, we would also need to know the email account with which you are registered in e-cost. You will then receive the official e-cost invitations that you will need to accept.
