Kitaev 1D p-wave chain: Majorana zero modes at the ends when |μ| < 2t

Layer 1 — Physicsin the topological-quantum-computing subtree

Kitaev 2001 toy model: a 1D spinless p-wave paired superconductor. H = Σ_j [−μ c_j†c_j − t(c_j†c_{j+1} + c_{j+1}†c_j) + Δ(c_j c_{j+1} + c_{j+1}†c_j†)]. Bogoliubov-de-Gennes spectrum gapped for all μ except at |μ| = 2t, where the bulk…
