Pith. sign in

Instead, for the quadratic model, it scales as 1 /ω3

This coincides with the finding in BCS theory based on the standard linear electron-phonon coupling

Two-phonon pairing and superconductivity in $SrTiO_3$

cond-mat.supr-con · 2026-08-04 · conditional · novelty 6.0

The two-phonon pairing mechanism in SrTiO3 gives a small, monotonically doping-dependent Tc because the attraction is controlled by high-energy phonons, not the soft mode.
