Researchers identify new type of superconductor
By David Nutt |September 21, 2020 Until now, the history of superconducting materials has been a tale of two types: s-wave and d-wave. Now, Cornell researchers – led by Brad Ramshaw, the Dick & Dale Reis Johnson Assistant Professor in the College of Arts and Sciences – have discovered a possible third type: g-wave. Their paper, “Thermodynamic Evidence for a Two-Component Superconducting Order Parameter in Sr2RuO4,” published Sept. 21 in Nature Physics. The lead author is doctoral student Sayak Ghosh, M.S. ’19. Electrons in superconductors move together in what are…
