Summary

Story summary

Researchers at University of Science and Technology of China and Southern University of Science and Technology observed a nodeless superconducting gap and detected electron-boson coupling in nickel-oxide thin films.
The results were published online in Science.
Xue Qikun, a Chinese Academy of Sciences academician, said nodeless gap suggests nickel-based superconductors follow different rules than copper-based ones.
The work reflects China’s deepening role in frontier physics and superconductivity research.
