Scaling properties of many-fermion systems from MCRG studies

Understand

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.
