商品描述
This book presents thermal field theory techniques, which can be applied in both cosmology and the theoretical description of the QCD plasma generated in heavy-ion collision experiments. It focuses on gauge interactions (whether weak or strong), which are essential in both contexts. As well as the many differences in the physics questions posed and in the microscopic forces playing a central role, the authors also explain the similarities and the techniques, such as the resummations, that are needed for developing a formally consistent perturbative expansion. The formalism is developed step by step, starting from quantum mechanics; introducing scalar, fermionic and gauge fields; describing the issues of infrared divergences; resummations and effective field theories; and incorporating systems with finite chemical potentials. With this machinery in place, the important class of real-time (dynamic) observables is treated in some detail. This is followed by an overview of a number of applications, ranging from the study of phase transitions and particle production rate computations, to the concept of transport and damping coefficients that play a ubiquitous role in current developments.
The book serves as a self-contained textbook on relativistic thermal field theory for undergraduate and graduate students of theoretical high-energy physics.
商品描述(中文翻譯)
這本書介紹了熱場理論技術，這些技術可以應用於宇宙學以及在重離子碰撞實驗中產生的量子色動力學（QCD）等離子體的理論描述。它專注於規範相互作用（無論是弱相互作用還是強相互作用），這在這兩個背景中都是至關重要的。除了在所提出的物理問題和在微觀力方面的許多差異外，作者還解釋了相似之處以及發展形式上自洽的微擾展開所需的技術，例如重整化。這一形式主義是逐步發展的，從量子力學開始；引入標量場、費米子場和規範場；描述紅外發散問題；重整化和有效場理論；並納入具有有限化學勢的系統。在這些工具到位後，重要的實時（動態）可觀測量被詳細處理。接下來是對多個應用的概述，範圍從相變的研究和粒子產生率計算，到在當前發展中扮演普遍角色的傳輸和阻尼係數的概念。
這本書作為一部自成體系的教科書，適合理論高能物理的本科生和研究生。

After obtaining a PhD in theoretical physics from the University of Helsinki, in 1994, Mikko Laine held postdoctoral positions at the University of Heidelberg, 1995 - 1997, and at the Theory Division at CERN, 1997 - 2003. For 2003 - 2012 he was a professor of theoretical physics at the University of Bielefeld; since 2012 he is a professor of theoretical physics at the University of Bern.
Aleksi Vuorinen obtained his PhD in theoretical physics from the University of Helsinki in 2004, and thereafter worked as a postdoctoral researcher at the University of Washington, 2004-2007, the Technical University of Vienna, 2007, as well as the Theory Division of CERN, 2008-2009. From 2009 to 2013, he headed a Sofja Kovalevskaja research group at the University of Bielefeld, after which he returned to Helsinki, where he currently works as a research group leader at the Helsinki Institute of Physics.
