WebbThe MK renormalization scheme has been ap- plied to a large variety of lattice models with per- iodic boundary conditions (e.g. [15-18, 25]). For all of these models, the effect of a free surface can be easily investigated by our approach. The paper is organized as follows.
WebbRenormalization group explained. In theoretical physics, the term renormalization group (RG) refers to a formal apparatus that allows systematic investigation of the changes of a physical system as viewed at different scales.In particle physics, it reflects the changes in the underlying force laws (codified in a quantum field theory) as the energy scale at … raymond nelson polygraphWebbJ.
