Phase diagram of a non-Abelian Aubry-André-Harper model with<mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"><mml:mi>p</mml:mi></mml:math>-wave superfluidity
We study theoretically a one-dimensional quasiperiodic Fermi system with topological $p$-wave superfluidity, which can be deduced from a topologically nontrivial tight-binding model on the square lattice in a uniform magnetic field and subject to a non-Abelian gauge field. The system may be regarded as a non-Abelian generalization of the well-known …
