Three-dimensional non-Abelian generalizations of the Hofstadter model: spin-orbit-coupled butterfly trios
Vincent Liu, Yi Yang, John D. Joannopoulos +1
We theoretically introduce and study a three-dimensional Hofstadter model with linearly varying non-Abelian gauge potentials along all three dimensions. The model can be interprete…
