Query: Coupled-layer description of topological crystalline insulators   We introduce a coupled-layer construction to describe three-dimensional
topological crystalline insulators protected by reflection symmetry. Our
approach uses stacks of weakly-coupled two-dimensional Chern insulators to
produce topological crystalline insulators in one higher dimension, with
tunable number and location of surface Dirac cones. As an application of our
formalism, we turn to a simplified model of topological crystalline insulator
SnTe, showing that its protected surface states can be described using the
coupled layer construction.
