Kitaev honeycomb lattice
Web1 mei 2024 · The Kitaev and Heisenberg exchange couplings are denoted as K and J, respectively. The system has two kinds of neighboring links and they appear alternately along the chain. Thus, the structural unit cell contains two lattice sites. Hereafter, we call the links ( 2 i − 1, 2 i) and ( i, 2 i + 1) as “ x -link” and “ y -link”, respectively. WebM.
