Termination-Controlled Fractionalization and Hybridization at Topological Interfaces in Organic Spin Chains
Khalid N. Anindya, Hong Guo
A single organic spin platform hosts both dimerized and effective Haldane sectors, linked by bond-texture inversion. At the junction, the fractional mode is…

Tunable Topological Phases in an Organic One-Dimensional Mott Chain: Odd-Haldane (S = 1/2) and Haldane (S = 1)
Khalid N. Anindya, Hong Guo
Establishing symmetry-protected topological (SPT) phases with interactions in chemically realistic systems remains an open challenge. We show that a single, synthetically plausible…
