Query: Novel Magnetic Quantization of sp$^{3}$ Bonding in Monolayer Tinene   A generalized tight-binding model, which is based on the subenvelope
functions of the different sublattices, is developed to explore the novel
magnetic quantization in monolayer gray tin. The effects due to the $sp^{3}$
bonding, the spin-orbital coupling, the magnetic field and the electric field
are simultaneously taken into consideration. The unique magneto-electronic
properties lie in two groups of low-lying Landau levels, with different orbital
components, localization centers, state degeneracy, spin configurations, and
magnetic- and electric-field dependences. The first and second groups mainly
come from the $5p_{z}$ and ($5p_{x}$,$5p_{y}$) orbitals, respectively. Their
Landau-level splittings are, respectively, induced by the electric field and
spin-orbital interactions. The intragroup anti-crossings are only revealed in
the former. The unique tinene Landau levels are absent in graphene, silicene
and germanene.
