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…
Self-organised magnon condensation in quasi-1D edge-shared cuprates without external fields
Cliò Efthimia Agrapidis, Stefan-Ludwig Drechsler, Satoshi Nishimoto
Multimagnon bound states were predicted nearly a century ago and have since been a key topic in condensed matter physics due to their intriguing quantum properties. However, their…
Topology of chalcogen chains
Adam KÅosiÅski, Wojciech Brzezicki, Alexander Lau +4
We investigate the topological properties of the helical atomic chains occurring in elemental selenium and tellurium. We postulate a realistic model that includes spin-orbit intera…
The fate of the spin polaron in the 1D antiferromagnets
Piotr Wrzosek, Adam Kosinski, Yao Wang +3
The stability of the spin polaron quasiparticle, well established in studies of a single hole in the 2D antiferromagnets, is investigated in the 1D antiferromagnets using a t-J mod…
