For over three decades, scientists have chased the dream of room-temperature superconductivity. Now, harnessing the raw power of cutting-edge supercomputers, researchers are unraveling the mysterious interactions within superconductors – unlocking insights that could lead to practical materials capable of conducting electricity with zero resistance, and effectively changing the world as we know it.

We present a theoretical prediction of a phonon-mediated two-gap superconductivity in infinite-layer nickelates Nd1−xSrxNiO2 by performing ab initio GW and GW perturbation theory calculations. Electron GW self-energy effects significantly alter the characters of the two-band Fermi surface and enhance the electron-phonon coupling, compared with results based on density functional theory.
