Topological Classification of Insulators: I. Non-interacting Spectrally-Gapped One-Dimensional Systems
We study non-interacting electrons in disordered one-dimensional materials which exhibit a
spectral gap, in each of the ten Altland-Zirnbauer symmetry classes. We define an …

Exponential decay of the critical points in a discrete model of polyacetylene
In this paper we consider stationary states of the SSH model for infinite polyacetylene chains
that are homoclinic or heteroclinic connections between two-periodic dimerized states. We …
