Efimov physics from a renormalization group perspective

TL;DR

This paper explores the Efimov effect through the lens of renormalization group theory, highlighting its experimental evidence in ultracold gases and nuclear physics, and emphasizing the concept of limit cycles.

Contribution

It offers a novel perspective on Efimov physics by applying renormalization group analysis and discussing recent experimental validations.

Findings

Evidence of Efimov states in ultracold gases

Relevance of Efimov physics in nuclear systems

Application of limit cycle concepts in renormalization group

Abstract

We discuss the physics of the Efimov effect from a renormalization group viewpoint using the concept of limit cycles. Furthermore, we discuss recent experiments providing evidence for the Efimov effect in ultracold gases and its relevance for nuclear systems.
