Mechanisms for Superconductivity

Sponsored by CCQ under the auspices of the New York City-Max Planck Center on Nonequilibrium Quantum Phenomena, the Conference  is a small focused workshop on mechanisms for superconductivity in materials ranging from the “nearly conventional”, such as transition metal dichalcogenides, or perhaps doped SrTiO3, to the “strongly correlated” including FeSe and Moire materials, as well as theoretical models ranging from bipolarons to quantum critical pairing. The aim of the conference is to bring together a select group of scientists to explore theoretically controlled calculations, compare methodologies,  determine experimental validation strategies and to assess the current state of the field and define directions for future research. We aim for an intense workshop atmosphere, with many questions during talks and with ample time for collaboration and discussion.

 

In person registration is now closed. If you wish to follow the talk via zoom please register here.
