**Abstract: ** Three-body problems are notoriously difficult to solve both in classical and
quantum physics. More then four decades ago Vitaly Efimov found a
surprisingly simple solution of a quantum mechanical problem of three
resonantly interacting non-relativistic bosons. He discovered an infinite
tower of geometrically spaced three-body bound states arising at the
two-body resonance. Only recently the advent of beautiful experiments with
ultracold atoms allowed us to see the signatures of the Efimov effect
experimentally. It turns out that in two spatial dimensions resonantly
interacting non-relativistic fermions form few-body bound states similar to
the ones predicted by Efimov. I will explain how this super Efimov effect
can be derived from the renormalization group calculation and describe its
possible implications for the many-body physics of topological chiral
superfluids.
