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 …

Nuclear halos emerge as new degrees of freedom near the neutron and proton driplines.
They consist of a core and one or a few nucleons which spend most of their time in the …

We consider the ground-state properties of an impurity particle (“polaron”) resonantly
interacting with a Bose-Einstein condensate (BEC). Focusing on the equal-mass system, we …

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

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 study universal bosonic few-body systems within the framework of effective field theory
at leading order (LO). We calculate binding energies of systems of up to six particles and the …

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 properties of the excited state of 4 He, 4 He∗, within the framework of
Efimov physics and its connection to the unitary point of the nuclear interaction. We explore …

The large values of the singlet and triplet scattering lengths locate the two-nucleon system
close to the unitary limit, the limit in which these two values diverge. As a consequence, the …

Motivated by recent experimental investigations of Cs-Cs-Li Efimov resonances, this work
theoretically investigates the few-body properties of N-1 noninteracting identical heavy …
