Local quenches in fracton field theory: Lieb-Robinson bound, non-causal dynamics and fractal excitation patterns

Dmitry S. Ageev, Andrey A. Bagrov, Aleksandr I. Belokon +3

We study the out-of-equilibrium dynamics induced by a local perturbation in fracton field theory. For the ${\mathbb{Z}}_4$ and ${\mathbb{Z}}_8$-symmetric free fractonic theories, we…
