TopoChain Designer

Inverse design for solvable 1D topological hopping chains.

Design topological edge and interface states in a solvable 1D chain.

Specify a target bulk gap, edge-state energy, and interface-state energy. TopoChain returns hopping parameters and verifies the design by direct diagonalization.

For synthetic 1D topological hopping-chain models. Not a general material-design tool.

Inverse design

Specify W_target and optional edge energies; the solver returns Δ, tA_left, and tA_iface hopping parameters.

Topological protection

Zak phase classification distinguishes trivial (0) from topological (π) phases with protected edge states.

Verified results

Optional numeric eigenvalue verification confirms designed parameters against finite chain Hamiltonians.
