Mapping Chern numbers in quasi-periodic interacting spin chains
Yifei Liu, Emil Prodan
Quasi-periodic quantum spin chains were recently found to support many topological phases in the finite magnetization sectors. They can simulate strong topological phases from clas…

Topological numbers of Happer model with "puzzling" degeneracy in periodic magnetic field
Yingkai Liu, Yifei Liu, Li-Wei Yu
The Happer model, as the variation of Rabi-Breit model, describes the interactions between the total nuclear spin and the total electron spin-1 of the triplet dimer molecules of ${…
