Geometric Rashba Control of Polar Pairing at LaAlO$_3$/KTaO$_3$ Interfaces
Overdamped polar nanoregion fluctuations provide the pairing glue at LaAlO3/KTaO3 interfaces, with geometric Rashba coupling yielding λ(θ) = λ0 + C sin²(θ) that maps to the observed quasi-linear Tc(θ) via Eliashberg solutions.
