摘要

通过二体力耦合并在一维晶格上运动的任何电子哈密顿的散射特征状态都被证明是贝特波函数。基态能量与之前通过另一种基于贝特波函数的程序并在相关费米气体框架内获得的哈伯德哈密顿的能量值进行了比较。同样的分析也适用于在相邻位点上相互作用的电子。在热力学的帮助下，对这些不同基态的重要性进行了评估。

Bethe’s Wave-Function Revisited

The scattering eigenstates of any Hamiltonian of electrons, coupled through a two-body force and moving on a one-dimensional lattice, are shown to be Bethe’s wave-functions. The energy of the groundstate is compared with values, obtained previously for the Hubbard Hamiltonian thanks to another Bethe’s wave-function-based procedure and within the framework of the correlated Fermi gas. The same analysis is applied to electrons, interacting on neighbouring sites. The significance of those various groundstates is assessed with help of thermodynamics.

期刊介绍： The Journal of Superconductivity and Novel Magnetism serves as the international forum for the most current research and ideas in these fields. This highly acclaimed journal publishes peer-reviewed original papers, conference proceedings and invited review articles that examine all aspects of the science and technology of superconductivity, including new materials, new mechanisms, basic and technological properties, new phenomena, and small- and large-scale applications. Novel magnetism, which is expanding rapidly, is also featured in the journal. The journal focuses on such areas as spintronics, magnetic semiconductors, properties of magnetic multilayers, magnetoresistive materials and structures, magnetic oxides, etc. Novel superconducting and magnetic materials are complex compounds, and the journal publishes articles related to all aspects their study, such as sample preparation, spectroscopy and transport properties as well as various applications.
