Crossed real nodal-line phonons in gold monobromide
Yilin Han, Yichen Liu, Chaoxi Cui +2
Spacetime inversion symmetry can generate intriguing types of spinless excitations in crystalline materials. Here, we propose a topological phase protected by spacetime inversion s…
Valley polarization in twisted altermagnetism
San-Dong Guo, Yichen Liu, Cheng-Cheng Liu
The combination of altermagnetism, twistronics and valleytronics is of great significance for potential applications in advanced electronic devices. Twisted magnetic van der Waals…
Creation and Manipulation of Higher-Order Topological States by Altermagnets
Yu-Xuan Li, Yichen Liu, Cheng-Cheng Liu
We propose to implement tunable higher-order topological states in a heterojunction consisting of a two-dimensional (2D) topological insulator and the recently discovered altermagn…
Twisted Magnetic Van der Waals Bilayers: An Ideal Platform for Altermagnetism
Yichen Liu, Junxi Yu, Cheng-Cheng Liu
We introduce a universal methodology for generating and manipulating altermagnetism in two-dimensional (2D) magnetic van der Waals (MvdW) materials through twisting. We find that a…
