Anomalous localization at the boundary of an interacting topological insulator

The boundary of a topological insulator (TI) hosts an anomaly restricting its possible phases: e.g. 3D strong and weak TIs maintain surface conductivity at any disorder if symmetry is preserved on-average, at least when electron interactions on the surface are weak. Expand abstract.

Multipolar Topological Field Theories: Bridging Higher Order Topological Insulators and Fractons

Two new recently proposed classes of topological phases, namely fractons and higher order topological insulators (HOTIs), share at least superficial similarities. Expand abstract.

Elastic higher-order topological insulators with quantization of the quadrupole moments

Both one-dimensional (1D) topological edge states and zero-dimensional (0D) topological corner states are visualized and can be transformed each other by tuning the crystalline symmetry in a hierarchical structure. Expand abstract.

Floquet topological insulators: from band structure engineering to novel non-equilibrium quantum phenomena

Outside the context of mesoscopic transport, the main challenge of inducing stable topological phases in many-body Floquet systems is their tendency to absorb energy from the drive and thereby to heat up. Expand abstract.

Stability of dynamical quantum phase transitions in quenched topological insulators: From multiband to disordered systems

This leads to an intriguing order of limits problem which we address by extensive numerical calculations on quenched one-dimensional topological insulators and superconductors with disorder. Expand abstract.
