论文摘要
我们通过重点关注基态的能量摩托米分散关系，与由光明的冷凝物和由轻度的dirac fermion和非差异杂质费米亚组成的底层，研究了两种不同类型的相对论近代效应，以重强度的自由度为特征。繁重的费米恩自由度是根据两种类型的重屈术有效理论引入的，换句话说，这是重型迪拉克费米恩的两个重型限制限制，这被称为高能物理学中的重夸克有效理论（HQET）。虽然第一个仅包含重粒子组件，但第二个组件既包含重粒子和重型粒子组件，又有其奇偶元相反。从这些理论中，我们获得了两种类型的近藤效应，其中费米表面附近的分散体非常相似，但是它们在低动量下的结构有所不同。我们还在两个限制中对可能的冷凝物形式进行了分类。将通过Dirac/Weyl Semimetals或Quark Matter，晶格模拟和冷原子模拟的实验来检查这两个临床效应。
We investigate two different types of relativistic Kondo effects, distinguished by heavy-impurity degrees of freedom, by focusing on the energy-momentum dispersion relations of the ground state with condensates composed of a light Dirac fermion and a nonrelativistic impurity fermion. Heavy fermion degrees of freedom are introduced in terms of two types of heavy-fermion effective theories, in other words, two heavy-fermion limits for the heavy Dirac fermion, which are known as the heavy-quark effective theories (HQETs) in high-energy physics. While the first one includes only the heavy-particle component, the second one contains both the heavy-particle and heavy-antiparticle components, which are opposite in their parity. From these theories, we obtain two types of Kondo effects, in which the dispersions near the Fermi surface are very similar, but they differ in the structure at low momentum. We also classify the possible forms of condensates in the two limits. The two Kondo effects will be examined by experiments with Dirac/Weyl semimetals or quark matter, lattice simulations, and cold-atom simulations.
