研究了环和开链上费米子跳跃模型的纠缠哈密顿量,确定了单粒子谱、本征函数及其在真实的空间中的形式。对于链,我们找到了一个与环一样的交换算子,并比较了它在两种情况下的性质。特别是,发现大系统的特征值之间的比例关系。我们还展示了如何进行的关键横向伊辛模型的换向属性。
We study the entanglement Hamiltonian for fermionic hopping models on rings and open chains and determine single-particle spectra, eigenfunctions and the form in real space. For the chain, we find a commuting operator as for the ring and compare with its properties in both cases. In particular, a scaling relation between the eigenvalues is found for large systems. We also show how the commutation property carries over to the critical transverse Ising model.
