Non-Hermitian non-Abelian topological insulators with $PT$ symmetry [PDF]
Phys. Rev. Research 3, 043006 (2021), 2021 We study a non-Hermitian non-Abelian topological insulator preserving $PT$ symmetry, where the non-Hermitian term represents nonreciprocal hoppings. As it increases, a spontaneous $PT$ symmetry breaking transition occurs in the perfect-flat band model from a real-line-gap topological insulator into an imaginary-line-gap topological insulator.
