| 英文摘要 | We investigate the butterfly effect and charge diffusion near the quantum phase transition in holographic approach. we argue that their criticality is controlled by the holographic scaling geometry with deformations induced by a relevant operator at finite temperature. specifically, in the quantum critical region controlled by a single fixed point, the butterfly velocity decreases when deviating from the critical point. while, in the non-critical region, the behavior of the butterfly velocity depends on the specific phase at low temperature. moreover, in the holographic berezinskii-kosterlitz-thouless transition, the universal behavior of the butterfly velocity is absent. finally, the tendency of our holographic results matches with the numerical results of bose-hubbard model. a comparison between our result and that in the o(n) nonlinear sigma model is also given. |
