Lecture

Renormalization Group: Energy Flow

Description

This lecture covers the concept of renormalization group and energy flow in the context of statistical physics. The instructor explains how to calculate specific heat by looking at the free energy and discusses the transformation of the partition function. The lecture delves into extensive and intensive free energy, emphasizing the importance of understanding the energy flow during the renormalization process. The instructor also explores the critical points and the behavior of correlation functions near the critical temperature, highlighting the exponential decay of correlations. The discussion extends to the linearization process around critical points to derive critical exponents, providing insights into the behavior of physical systems at different temperatures.
