Oral: Weak topology and Anderson metal-insulator transition in Chiral class

Chiral symmetric systems in two dimensions lack conventional topological characteristics but exhibit weak topological phases induced by SSH-like staggering bonds. We explore the impact of this topology on the Anderson localization transition in the Chiral class. Topology induces anisotropy in the transport properties of these systems. To illustrate this, we examine a bond-dimer model on a two dimensional square lattice that features a weak-topological insulator phase, a trivial insulating phase and a critical metallic phase, creating a diverse phase diagram that effectively demonstrates the interplay between topology and the Anderson transition. We discuss the universality of this localization transition within the Chiral class.
