Catalog of Altermagnetism in Magnetic Wallpaper/Space Groups and Nonsymmorphic Altermagnets
Congcong Le, Fan Cui, Iao-Fai Io +3
Conventional altermagnetism, characterized by compensated collinear spin alignment and spin splitting, exhibits identical spin states at opposite momenta. In this work, we employ a…
Non-Hermitian free-fermion critical systems and logarithmic conformal field theory
Iao-Fai Io, Fu-Hsiang Huang, Chang-Tse Hsieh
Conformal invariance often accompanies criticality in Hermitian systems. However, its fate in non-Hermitian settings is less clear, especially near exceptional points where the Ham…
Quasi-Hermitian extended SSH models
Iao-Fai Io, Cheng-Yuan Huang, Jhih-Shih You +2
We consider the quasi Hermitian limit of a non-Hermitian extended Su Schrieffer Heeger model, in which the hopping amplitudes obey a specific relation so that the system may be map…
Winding number and Zak phase in multi-band SSH models
Chen-Shen Lee, Iao-Fai Io, Hsien-chung Kao
We use multi-band SSH models to demonstrate a prescription for calculating the correct Zak phase and winding number of multi-band systems. We verify our prescription by comparing t…
