'Failed superconductivity' paper published in Nature

Our study on anomalous metals and superconductors in rhombohedral graphene has been published in Nature. This work, done in collaboration with the Folk group at UBC, addresses a growing mystery of states that resemble superconductors yet have a finite saturation resistance, rather than zero. Similar features have been seen across a wide variety of thin-film superconductors over the past four decades, and there is currently no accepted theory for the phenomenon. In ultra-clean rhombohedral graphene, we find that proper zero-resistance states can sit beside ‘failed’ superconductors in phase space, separated by small changes in doping. We anticipate that the tunability of rhombohedral graphene will open new pathways towards understanding this mysterious behavior.

The exceptional richness of rhombohedral graphene continues to provide new surprises. Congratulations to Anna, Abigail, Tobias, and all our co-authors!
