Two distinct superconducting pairing states divided by the nematic end point in FeSeS
T. Hanaguri, K. Iwaya, Y. Kohsaka +5
Unconventional superconductivity often competes or coexists with other electronic orders. In iron-based superconductors, relationship between superconductivity and the nematic stat…
