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.
