icosahedral diffraction symmetry and sharp Bragg reflections published. A paradigm shift …

Quantum spin Hall effect and spin Bott index in a quasicrystal lattice

H Huang, F Liu - Physical review letters, 2018 - APS
Despite the rapid progress in the field of the quantum spin Hall (QSH) effect, most of the
