基于MCRG研究的多费米子系统的标度性质

Scaling properties of many-fermion systems from MCRG studies

Anna Hasenfratz

摘要:

Monte Carlo重整化群方法被设计用于研究统计系统的相结构和临界行为。它们非常适合于确定运行耦合和研究规范费米子模型的不动点的性质,包括在多费米子系统中共形红外不动点的存在性。讨论了2格点匹配方法的实现,给出了N_f= 0,12和16基本费米子味的SU(3)规范理论的结果。

英文摘要:

Monte Carlo renormalization group methods were designed to study the phase structure and critical behavior of statistical systems. They are well suited to determine the running coupling and to investigate the properties of fixed points of gauge-fermion models, including the existence of conformal infrared fixed points in many-fermion systems. I discuss the implementation of the 2-lattice matching method and present results for SU(3) gauge theories with N_f=0,12 and 16 fundamental fermion flavors.
