Instability of metals with respect to strong electron-phonon interaction
Emil A. Yuzbashyan, Boris L. Altshuler, Aniket Patra
We show that thermal equilibrium between conduction electrons and phonons becomes kinetically unstable when the renormalized electron-phonon coupling exceeds a certain threshold. W…
