Classification of topological ladder models into six types (three BDI, three AIII) linked to Wilson fermion configurations, with bowtie ladder as canonical geometry from which others derive via unitary transformation.
If a model has no diagonal couplings, that is t = t′ = 0, the condition for chiral symmetry (138) is fulfilled independently of the rest of the parameters
