Rashba-Hubbard链与Hubbard链的等价性

Equivalence of Rashba-Hubbard and Hubbard chains

Florian Goth, Fakher F. Assaad

摘要:

我们回顾了U(1)规范对称性使具有Rashba型自旋轨道耦合的一维Hubbard链映射到重整化Hubbard哈密顿量的事实。映射的存在有重要的后果ARPES实验的解释一维链Rashba自旋轨道耦合,可以利用检查映射的适用性。我们展示了映射的数值应用,并考虑玻色子化以及海森堡极限的哈伯德模型的影响。此外,我们指出了各种广义哈伯德模型的后果。

英文摘要:

We review the fact that U(1) gauge symmetry enables the mapping of one-dimensional Hubbard chains with Rashba-type spin orbit coupling to renormalized Hubbard Hamiltonians. The existence of the mapping has important consequences for the interpretation of ARPES experiments on one-dimensional chains subject to Rashba spin orbit coupling and can be exploited to check for the applicability of the mapping. We show numerical applications of the mapping and consider the implications for bosonization as well as for the Heisenberg-limit of the Hubbard model. In addition we point out the consequences for various generalized Hubbard models.
