This explanation is amazing!
Excellent explanation..thanks a lot.
Excellent Explanation. Question for professor: inversion symmetry is required for Toplogical Insulator?
SSH has no band inversion in the bulk, it also has edge modes but they are protected by the chiral symmetry of the chain (and of the Hamiltonian).
