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 Gaps in Quasi-Periodic Spin Chains: A Numerical and K-Theoretic Analysis
Yifei Liu, Lea F. Santos, Emil Prodan
Topological phases supported by quasi-periodic spin-chain models and their bulk-boundary principles are investigated by numerical and K-theoretic methods. We show that, for both th…
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 ${…
Degenerate Rayleigh-Plateau instability in a magnetically annealed colloidal dispersion
James W. Swan, Yifei Liu, Eric M. Furst
This fluid dynamics video depicts the evolution of a suspension of paramagnetic colloids under the influence of a uniform, pulsed magnetic field. At low pulse frequencies, the susp…
