Dynamic properties of two-dimensional latticed holographic system

A bstract We study the anisotropic properties of dynamical quantities: direct current (DC) conductivity, butterfly velocity, and charge diffusion. The anisotropy plays a crucial role in determining phase structure two-lattice system. Even small deviation from isotropy can lead to distinct structures, as well IR fixed points our holographic systems. In particular, for cases, most important property is that point be non-AdS 2 × ℝ even metallic phases. As one-lattice system, velocity diffusion also diagnose quantum transition (QPT) this two-dimensional latticed
