This article reviews theoretical and experimental advances in Efimov physics, an array of
quantum few-body and many-body phenomena arising for particles interacting via short …

Physical systems characterized by a shallow two-body bound or virtual state are governed at
large distances by continuous scale invariance, which is broken into discrete scale …

We provide a general discussion on the importance of three-body Efimov physics for
strongly interacting ultracold quantum gases. Using the adiabatic hyperspherical …

The composite nature of a shallow bound state is studied by using the weak-binding
relation, which connects the compositeness of the bound state with observables. We first …

We investigate the appearance of a four-boson limit cycle in Hamiltonian systems at the
unitarity limit. The model interaction incorporates two-, three-, and four-body short-range …

We investigate the spin entanglement in few-nucleon scattering processes involving
nucleons and deuterons. For this purpose, we consider the entanglement power introduced …

We study the universality of the three-body parameters for systems relevant for ultracold
quantum gases with positive s-wave two-body scattering lengths. Our results account for …

Universal behavior has been found inside the window of Efimov physics for systems with N=
4, 5, 6 particles. Efimov physics refers to the emergence of a number of three-body states in …

Generally, the three-body recombination (TBR) of the ultracold helium atoms in the zero-
collision-energy limit could be described by the original zero-range (Efimov) universal …

The three-body system inside the unitary window is studied for three equal bosons and three
equal fermions having 1/2 spin-isospin symmetry. We perform a Gaussian characterization …
