摘要:

我们建立了具有均匀p体相互作用的一类Sachdev-Ye-Kitaev(SYK)模型的可积性。我们推导出生成这些模型哈密顿量的R矩阵和相互交换的转移矩阵,并获得了它们的精确本征谱和本征态。值得注意的是,R矩阵是临界 transverse-field Ising链的R矩阵。这项工作揭示了SYK模型——许多体量子混沌的核心——与临界ISING链——统计力学的基石——之间意想不到的联系。

英文摘要:

We establish the integrability of a family of Sachdev-Ye-Kitaev (SYK) models with uniform $p$-body interactions. We derive the R-matrix and mutually commuting transfer matrices that generate the Hamiltonians of these models, and obtain their exact eigenspectra and eigenstates. Remarkably, the R-matrix is that of the critical transverse-field Ising chain. This work reveals an unexpected connection between the SYK model, central to many-body quantum chaos, and the critical Ising chain, a cornerstone of statistical mechanics.
