Since the pioneering work of Lüscher in the 1980s it is well known that considering quantum
systems in finite volume, specifically, finite periodic boxes, can be used as a powerful …

We study systems of bosons and fermions in finite periodic boxes and show how the
existence and properties of few-body resonances can be extracted from studying the volume …

Background: The nuclear optical potential is a successful tool for the study of nucleon-
nucleus elastic scattering and its use has been further extended to inelastic scattering and …

The Borromean nucleus 17Ne (15O+ p+ p) is investigated by using the hyperspheric
adiabatic expansion for a three-body system. The measured size of 15O and the low-lying …

The inclusion of the continuum in the study of weakly bound three-body systems is
discussed. A transformed harmonic oscillator basis is introduced to provide an appropriate …

The nature of the Λ nn and H* Λ 3 (J π= 3/2+, I= 0) states is investigated within a pionless
effective field theory at leading order, constrained by the low-energy Λ N scattering data and …

We solve the persistent problem of the structure of the lowest 1/2+ resonance in 9Be which
is important to bridge the A= 8 gap in nucleosynthesis in stars. We show that the state is a …

We discuss the three-body decay mechanisms of many-body resonances. Sequential
decays proceed via two-body configurations after emission of the third particle. In direct …

We investigate the $^{9} _ {\phi} $ Be and $^{6} _ {\phi\phi} $ He hypernuclei within the
framework of the three-body cluster model% specifically as the $\phi $+ $\alpha $+ $\alpha …

The lowest-lying states of the Borromean nucleus Ne 17 (O 15+ p+ p) and its mirror nucleus
N 17 (N 15+ n+ n) are compared by using the hyperspheric adiabatic expansion. Three …
