Energy diffusion and the butterfly effect in inhomogeneous Sachdev-Ye-Kitaev chains Journal Article uri icon



  • We compute the energy diffusion constant; DD,; Lyapunov time; tau_{textsc{l}}; and butterfly velocity; v_{textsc{b}}; in an inhomogeneous chain of coupled Majorana Sachdev-Ye-Kitaev (SYK); models in the large NN; and strong coupling limit. We find; Dle v_{textsc{b}}^2 tau_{textsc{l}}; from a combination of analytical and numerical approaches. Our example; necessitates the sharpening of postulated transport bounds based on; quantum chaos.
