Spin-orbit coupling in wurtzite quantum wells
J. Y. Fu, P. H. Penteado, D. R. Candido +4
Effective spin-orbit (SO) Hamiltonians for conduction electrons in wurtzite heterostructures are lacking in the literature, in contrast to zincblende structures. Here we address th…
High-degeneracy points protected by site-permutation symmetries
F. Crasto de Lima, G. J. Ferreira
Space group symmetries dictate the energy degeneracy of quasiparticles (e.g., electronic, photonic) in crystalline structures. For spinless systems, there can only be double or tri…
Topological flat band, Dirac fermions and quantum spin Hall phase in 2D Archimedean lattices
F. Crasto de Lima, Gerson J. Ferreira, R. H. Miwa
Materials with designed properties arises in a synergy between theoretical and experimental approaches. In this study we explore the set of Archimedean lattices forming a guidance…
Interplay between boundary conditions and Wilson's mass in Dirac-like Hamiltonians
A. L. Araújo, R. P. Maciel, R. G. F. Dornelas +2
Dirac-like Hamiltonians, linear in momentum , describe the low-energy physics of a large set of novel materials, including graphene, topological insulators, and Weyl fermions. W…
