Layer Hall effect induced by altermagnetism
Fang Qin, Rui Chen
In this work, we propose a scheme to realize the layer Hall effect in the ferromagnetic topological insulator BiSe via proximity to -wave altermagnets. We show that an a…

Tunable corner states in topological insulators with long-range hoppings and diverse shapes
Fang Qin, Rui Chen
In this work we develop a theoretical framework for the control of corner modes in higher-order topological insulators (HOTIs) featuring long-range hoppings and diverse geometries,…

Emergent Weyl-like points in periodically modulated systems
Fang Qin, Rui Chen
We investigate a three-dimensional (3D) topological phase resembling a Weyl semimetal, modulated by a periodic potential and engineered through Floquet dynamics. This system is con…
