A recent rejuvenation of experimental and theoretical interest in the physics of few-body
systems has provided deep, fundamental insights into a broad range of problems. Few-body …

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 …

The Lagrange-mesh method is an approximate variational method taking the form of
equations on a grid thanks to the use of a Gauss-quadrature approximation. The variational …

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

The Hyperspherical Harmonics (HH) method is one of the most accurate techniques to solve
the quantum mechanical problem for nuclear systems with a number of nucleons A≤ 4. In …

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 …

The role of an intrinsic four-body scale in universal few-boson systems is the subject of
active debate. We study these systems within the framework of effective field theory. For …

The large values of the singlet and triplet two-nucleon scattering lengths locate the nuclear
system close to the unitary limit. This particular position strongly constrains the low-energy …

Nuclear effective field theories (EFTs) have been developed over the last quarter-century
with considerable impact on the description of light and even medium-mass nuclei. At the …

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 …
