...Millis et al. (1996b) argued that a dynamical JT e!ect may persist at higher hole densities, without leading to long-range order but producing important #uctuations that localize electrons by splitting the degenerate e levels at a given MnO octahedron....

(1996) (see alsoMillis et al., 1996a; Millis, 1998) argued that the physics of manganites is dominated by the interplay between a strong electron}phonon coupling and the large Hund coupling e!ect that optimizes the electronic kinetic energy by the…...
