基于李 - 威尔切克(Lee - Wilczek)提出的涌现马约拉纳算符Γ,实现了一种新的双重简并。哈密顿量可通过杨 - 巴克斯特方程的新型解,即R矩阵来获得。对于两体相互作用,R给出了与一维基泰耶夫(Kitaev)链模型相同的“超导”链。通过三体R矩阵推导出了与Γ对易的三体哈密顿量,从而表明双重简并的本质源于此。我们还表明,扩展的Γ′算符是奇数N时辫子群$B_N$的一个不变量。此外,利用扩展的Γ′算符,我们构造了杨 - 巴克斯特方程解的高维矩阵表示,并发现其在构造奇数N的2N量子比特格林伯格 - 霍恩 - 泽林格(Greenberger - Horne - Zeilinger)态中的应用。
A new realization of doubling degeneracy based on emergent Majorana operator Γ presented by Lee-Wilczek has been made. The Hamiltonian can be obtained through the new type of solution of Yang-Baxter equation, i.e. -matrix. For 2-body interaction, gives the “superconducting” chain that is the same as 1D Kitaev chain model. The 3-body Hamiltonian commuting with Γ is derived by 3-body -matrix, we thus show that the essence of the doubling degeneracy is due to . We also show that the extended Γ′-operator is an invariant of braid group BN for odd N. Moreover, with the extended Γ′-operator, we construct the high dimensional matrix representation of solution to Yang-Baxter equation and find its application in constructing 2N-qubit Greenberger-Horne-Zeilinger state for odd N.
