Quaternary Jordan-Wigner mapping and topological extended-kink phase in the interacting Kitaev ring
Zhen-Yu Zheng, Han-Chuan Kou, Peng Li
On a ring, a single Jordan-Wigner transformation between the Kitaev model and the spin model suffers redundant degrees of freedom. However, we can establish an exact quaternary Jor…
