标题： Functional renormalization group study of the quark-meson model with omega and rho vector mesons

摘要： 功能重整化群(FRG)是一种非微扰方法，考虑量子和热涨落。 在本工作中，使用FRG流方程研究了在有限同位旋化学势下包含omega和rho矢量介子相互作用的两味夸克-介子模型的临界区域。 我们还使用传统的平均场方法计算手征极限下的相图以进行比较。 结果表明，omega介子和rho介子对相结构的影响差异很大。 同位旋化学势的存在也导致相结构发生显著变化。 显示英文摘要

摘要： The functional renormalization group (FRG) is a non-perturbative method that considers quantum and thermal fluctuations. Using the FRG flow equations, the critical region of the two-flavor quark-meson model in a finite isospin chemical potential with omega and rho vector mesons interactions is investigated in this work. We also use the traditional mean-field method to calculate the phase diagram in the chiral limit for comparison. The results show that the influences of the omega meson and rho meson on the phase structure are quite different. The existence of the isospin chemical potential also causes significant changes in the phase structure.
