Network model for magnetic higher-order topological phases
Hui Liu, Ali G. Moghaddam, Daniel Varjas +1
We propose a network-model realization of magnetic higher-order topological phases (HOTPs) in the presence of the combined space-time symmetry -- the product of a…

Floquet topological phases with time-reversal and space inversion symmetries and dynamical detection of topological charges
Hong Wu, Yu-Chen Dong, Hui Liu
For spinful systems with spin 1/2, it is generally believed that P and T invariant strong and second-order topologies exist in four band and eight band system, respectively. Here,…

Topological Weyl Altermagnetism in CrSb
Cong Li, Mengli Hu, Zhilin Li +12
Altermagnets constitute a novel, third fundamental class of collinear magnetic ordered materials, alongside with ferro- and antiferromagnets. They share with conventional antiferro…
