Robust Spin-1 Haldane Topology under Itinerant Doping

Satoshi Nishimoto

We study itinerant hole doping of the spin- $1$ Haldane symmetry-protected topological (SPT) phase in two $t$ -- $J$ chains coupled by ferromagnetic (FM) Hund exchange. Density-matrix…

Ground State Properties of the Doped Kitaev-Heisenberg Chain: Topological Superconducting and Mott Insulating Phases Driven by Magnetic Frustration

Cliò Efthimia Agrapidis, Satoshi Nishimoto

We study the hole-doped Kitaev-Heisenberg chain using the density-matrix renormalization group. In the Kitaev-only limit, the bond-directional exchange itself promotes pairing, fav…
