重整化群的引入及其在非相对论量子电子气体中的应用

Introduction to the Renormalization Group with Applications to Non-Relativistic Quantum Electron Gases

Vincent Rivasseau

摘要:

我们回顾了许多费米子模型的严格工作,导致在两个维度上的相互作用的费米液体的第一个结构,并允许证明,有不同的缩放制度在两个维度上,这取决于费米表面的形状。我们还回顾了三维情况下的进展。我们从量子场论和微扰重整化的教学介绍开始。然后重点放在使用费米面周围的重整化在一个建设性的方式,其中所有订单的微扰理论严格总结。

英文摘要:

We review the rigorous work on many Fermions models which lead to the first constructions of interacting Fermi liquids in two dimensions, and allowed to prove that there are different scaling regimes in two dimensions, depending on the shape of the Fermi surface. We also review progress on the three dimensional case. We start with a pedagogical introduction on quantum field theory and perturbative renormalization. Emphasis is then put on using renormalization around the Fermi surface in a constructive way, in which all orders of perturbation theory are summed rigorously.
