Description:
Author(s): Shun-Li Yu, Wei Wang, Zhao-Yang Dong, Zi-Jian Yao, and Jian-Xin Li The confinement and deconfinement of spinons in the square-lattice antiferromagnetic J 1 − J 2 Heisenberg model are elaborated by exploring the evolution of the whole excitation spectra with J 2 , based on the spin cluster perturbation theory. We find that deconfined spin- 1 / 2 spinons beyond the convention... [Phys. Rev. B 98, 134410] Published Mon Oct 08, 2018
