  • About the Edition

    This Brief presents an introduction to the theory of the renormalization group in the context of quantum field theories of relevance to particle physics. Emphasis is placed on gaining a physical understanding of the running of the couplings. The Wilsonian version of the renormalization group is related to conventional perturbative calculations with dimensional regularization and minimal subtraction. An introduction is given to some of the remarkable renormalization group properties of supersymmetric theories.

    What is Renormalization? The idea of renormalization is rather simple. Let me use three examples to explain it. The first example is something that everyone is familiar with: microphone-loudspeaker audio feedback. You place a microphone close enou.

In the general formulation of renormalization group in "statistical mechanics" by a, each point in parameter space is represented by a vector $\vec{K}$ and the transformed vector would be given by $$\vec{K}'=R(\vec{K})$$ If we look at what happens when it gets very close to the fixed point $\vec{K}^*$, then we would have.

The renormalization group answers this question through the theory of cross-over behaviour. The existence of such phenomena, whereby different fixed points may influence the properties of the same system on different length scales, is totally absent in mean field treatments.

First the basic ideas of dynamical systems (fixed points, stability, etc.) are recalled, and Author: Alessandro Sfondrini. The basin of attraction of a critical fixed point is also called critical can argue that the fact that all the points of a critical manifold flow towards the same fixed point (i.e.

the same Hamiltonian) is the basic mechanism on which universality is based upon, but this is by no means a complete explanation, since universality involves the behaviour of systems near a critical. This work tries to provide an elementary introduction to the notions of continuum limit and universality in statistical systems with a large number of degrees of freedom.

The existence of a continuum limit requires the appearance of correlations at large distance, a situation that is encountered in second order phase transitions, near the critical temperature.

Each chapter introduces a new key topic and develops the discussion in a self-contained manner. At the same time the selected topics have common themes running throughout the book, which connect the independent discussions. The main themes are renormalization group, fixed points, universality, and continuum limit, which open and conclude the : Oxford University Press.
