Renormalization Constants

The gauge dependence of the renormalization constant of the quark field has been studied with the help of the renormalization group method. In the case of the color gauge field an exact evaluation of the renormalization constant is feasible because of the presence of a sum rule, but in the absence of the corresponding sum rule, only a qualitative evaluation is possible for the quark field.

New Applications

The renormalization group (RG) method developed by Ken Wilson more than four decades ago has revolutionized the way we think about problems involving a broad range of energy scales such as phase transitions, turbulence, continuum limits and bifurcations in dynamical systems. The Theme Issue provides articles reviewing recent progress made using the RG method in atomic, condensed matter, nuclear and particle physics. In the following, we introduce these articles in a way that emphasizes common themes and the universal aspects of the method.
