Particles with short-range interactions and a large scattering length have universal low-
energy properties that do not depend on the details of their structure or their interactions at …

The theoretical status on universal aspects of weakly-bound neutron-rich light nuclei are
reviewed, considering few-body approaches. We focus the review on the low-energy …

The Efimov phenomenon manifests itself as an emergent discrete scaling symmetry in the
quantum three-body problem. In the unitarity limit, it leads to an infinite tower of three-body …

We show that an independent four-body momentum scale μ (4) drives the tetramer binding
energy for fixed trimer energy (or three-body scale μ (3)) and large scattering length (a). The …

The recently extracted matter radius of carbon isotope 22C allows us to estimate the mean-
square distance of a halo neutron with respect to the center-of-mass of this nucleus. By …

A systematic study of the root-mean-square distance between the constituents of weakly-
bound nuclei consisting of two halo neutrons and a core is performed using a renormalized …

We investigated temperature-dependent infrared-active transverse phonon modes of
geometrically frustrated pyrochlore Y 2 Ru 2 O 7, which exhibits a spin-glass-like transition …

We discuss how the bath's memory affects the dynamics of a swap gate. We present an
exactly solvable model that shows various dynamical transitions when treated beyond the …

We study triatomic systems in the regime of large negative scattering lengths which may be
more favorable for the formation of condensed trimers in trapped ultracold monoatomic …
