Web10 apr. 2024 · Z2 Spin Liquids in the Higher Spin- S Kitaev Honeycomb Model: An Exact Deconfined Z2 Gauge Structure in a Nonintegrable Model. Phys. Rev. Lett. 130, 156701 (2024) – Published 11 April 2024. The ground state of the half-integer spin Kitaev model is always a Z 2 spin liquid no matter what the interaction strengths are. WebThe Kitaev honeycomb model, first introduced in , is a system of spin-1/2 particles placed on the vertices of a hexagonal lattice. The system is known to exist in both Abelian and non-Abelian topological phases and is therefore relevant to on-going research into topologically fault-tolerant quantum information processing [ 2 – 4 ].
