Euclidean Field Theory

  title={Euclidean Field Theory},
  author={Kasper Peeters and Marija Zamaklar},
Summary: The generating functional of a Euclidean quantum field theory in dspace dimensions can alternatively be interpreted as a partition sum in a classicalstatistical model in d dimensions. The corresponding inverse temperature is thenrelated to Planck’s constant by b ˘1/¯h. I See also: Discussions like these can be found in many places, e.g. chapter 2 of thebook by Smit [10] or chapter V.2 of the book by Zee [13]. 1.3. Finite temperature quantum field theory In standard quantum field theory…

The evolution of the wave function in quantum mechanics is deterministic like that of classical waves. Only when we bring in observers the fundamentally different quantum reality emerges. Similarly



Quantum Field Theory and Critical Phenomena

Introduced as a quantum extension of Maxwell's classical theory, quantum electrodynamic (QED) has been the first example of a quantum field theory (QFT). Eventually, QFT has become the framework for

Quantum Field Theory at Finite Temperature: An Introduction

In these notes we review some properties of Statistical Quantum Field Theory at equilibrium, i.e Quantum Field Theory at finite temperature. We explain the relation between finite temperature quantum

Statistical Mechanics:

AbstractPROF. R. H. FOWLER'S monumental work on statistical mechanics has, in this the second edition, in his own modest words, been rearranged and brought more up to date. But the new volume is much

Scaling and Renormalization in Statistical Physics

This text provides a thoroughly modern graduate-level introduction to the theory of critical behaviour. Beginning with a brief review of phase transitions in simple systems and of mean field theory,

Quarks, Gluons and Lattices

This book introduces the lattice approach to quantum field theory. The spectacular successes of this technique include compelling evidence that exchange of gauge gluons can confine the quarks within

What is Renormalization

"Preprint" of paper from 1989 that wasn't arxiv'ed at the time. Abstract: Our understanding of quantum field theories, and, in particular, of renomalization has changed radically in recent years;

The Statistical Mechanics of Phase Transitions

Abstract This article traces the development and study of phase transitions from late last century to the present day. We begin with a brief historical sketch and a description of the statistical
