论文摘要
在低温下是费米液体的大多数过渡金属中观察到的居里 - 韦斯磁反应的起源一直是一个谜，几十年来，尚未从微观原理中充分说明。我们在单障碍安德森（Anderson）模型上显示了强电子相关性的量子动力学如何导致库里 - 韦斯 - 韦斯磁易感性足够高于昆多温度。这种行为尚未得到证明，只有在实质上筛选裸相互作用（重新归一化）并保持量子和热波动之间的平衡时才能观察到。我们为存在居里 - 韦斯法律的存在设定了定量标准。
The genesis of the Curie-Weiss magnetic response observed in most transition metals that are Fermi liquids at low temperatures has been an enigma for decades and has not yet been fully explained from microscopic principles. We show on the single-impurity Anderson model how the quantum dynamics of strong electron correlations leads to the Curie-Weiss magnetic susceptibility sufficiently above the Kondo temperature. Such behavior has not yet been demonstrated and can be observed only when the bare interaction is substantially screened (renormalized) and a balance between quantum and thermal fluctuations is kept. We set quantitative criteria for the existence of the Curie-Weiss law.
