Abstract

High-resolution STM/STS on Pb₁-xSnxSe step edges shows that translational-symmetry breaking at half-unit-cell steps, combined with chiral-symmetry breaking from rhombohedral distortion, produces a spectral asymmetry in the Landau-level flow. The work uses step edges as domain-wall sensors of hidden chiral symmetry breaking in a topological crystalline insulator.
