Query: Spin textures on general surfaces of the correlated topological
  insulator SmB6   Employing the $\mathbf{k}\cdot\mathbf{p}$ expansion for a family of
tight-binding models for SmB$_6$, we analytically compute topological surface
states on a generic $(lmn)$ surface. We show how the Dirac-cone spin structure
depends on model ingredients and on the angle $\theta$ between the surface
normal and the main crystal axes. We apply the general theory to $(001)$,
$(110)$, $(111)$, and $(210)$ surfaces, for which we provide concrete
predictions for the spin pattern of surface states which we also compare with
tight-binding results. As shown in previous work, the spin pattern on a $(001)$
surface can be related to the value of mirror Chern numbers, and we explore the
possibility of topological phase transitions between states with different
mirror Chern numbers and the associated change of the spin structure of surface
states. Such transitions may be accessed by varying either the hybridization
term in the Hamiltonian or the crystal-field splitting of the low-energy $f$
multiplets, and we compute corresponding phase diagrams.
