Superconducting dome in ferroelectric-type materials from soft mode instability

  author={C.S.G.K. Setty and Matteo Baggioli and Alessio Zaccone},
We present a minimal theory of superconductivity enhancement in ferroelectric-type materials. Simple expressions for the optical mode responsible for the soft mode transition are assumed. A key role is played by the anharmonic phonon damping which is modulated by an external control parameter (electron doping or mechanical strain) causing the appearance of the soft mode. It is shown that the enhancement in the superconducting critical temperature Tc upon approaching the ferroelectric transition…
