Title: The Efimov Effect

Abstract:  The Efimov effect, predicted by V. Efimov in 1970, is a surprising quantum phenomenon where three particles with short-range interactions can form an infinite sequence of bound states, even when no two-body subsystem is bound. Despite progress, key aspects remain unresolved.

This talk covers critical Schrödinger operators, virtual levels, and analytical techniques developed primarily by Yafaev, Zhislin and Vugalter. I will outline a methodology for identifying Efimov-type effects in multi-particle and mixed-dimensional systems.

Based on joint work with Semjon Vugalter, Dirk Hundertmark, and Sylvain Zalczer.
