Overview

Purpose

Functional Renormalization Group (FRG) is a powerful theoretical framework for investigating physical systems described by field theory. Its applications span a wide range of areas, from condensed matter and statistical physics to particle physics and gravity. This two-day workshop aims to provide an overview of recent applications and developments of FRG across various fields, foster discussions on future directions, and explore opportunities for new collaborations.

(This is RIKEN Quantum international workshop supported by RIKEN Quantum.)
