Abstract: Electron-phonon superconductors at high pressures have displayed the highest values of critical superconducting temperature $T_c$ on record, now rapidly approaching room temperature. Despite the importance of high-$P$ superconductivity in the quest for room-temperature superconductors, a… read more here.

DOI: 10.1103/physrevb.104.l220506
Abstract: We develop a theory of superconducting pairing in low-density Strontium titanate due to quadratic coupling of electron density to soft transverse optical phonons [1]. It leads to static attractive potential between electrons which decay length… read more here.
