We study the gauge field fluctuations in dense quark matter and determine the temperature of the induced first-order phase transition to the color-superconducting phase in weak coupling. We find that the local approximation of the coupling between the gauge potential and the order parameter, employed in the Ginzburg-Landau theory, has to be modified by restoring the full momentum dependence of the polarization function of gluons in the superconducting phase.
我们研究了致密夸克物质中的规范场涨落，并确定了弱耦合下诱导的向色超导相的一级相变温度。我们发现，金兹堡 - 朗道理论中采用的规范势与序参量之间耦合的局部近似，必须通过恢复超导相中胶子极化函数的全动量依赖性来修正。
