论文摘要
我们研究了近托效应的影响，即，杂质引起的非扰动效应对夸克物质中手性分离效应（CSE）的影响。我们采用了一个简单的有效模型，该模型融合了由光夸克和重夸克制成的近藤冷凝物，并以静态极限和动力学极限计算轴向电流对磁场的响应函数。结果，我们发现近托效应在两个限制中催化CSE，尤其是在动态极限下的CSE催化CSE，可以增强大约三倍。我们的发现清楚地表明，夸克物质中重杂质的存在可能在磁场引起的光夸克的传输现象中起重要作用。
We investigate the influence of Kondo effect, namely, the nonperturbative effect induced by heavy impurities, on the chiral separation effect (CSE) in quark matter. We employ a simple effective model incorporating the Kondo condensate made of a light quark and a heavy quark, and compute the response function of axial current to the magnetic field in static limit and dynamical limit. As a result, we find that the Kondo effect catalyzes the CSE in both the limits, and particularly the CSE in dynamical limit can be enhanced by a factor of approximately three. Our findings clearly show that the presence of heavy impurities in quark matter can play an important role in the transport phenomena of light quarks induced by a magnetic field.
