Static and Dynamic Properties of a Few Spin 1/2 Interacting Fermions Trapped in a Harmonic Potential
Mathematics, 2020 We provide a detailed study of the properties of a few interacting spin 1 / 2 fermions trapped in a one-dimensional harmonic oscillator potential. The interaction is assumed to be well represented by a contact delta potential.

Hadronic parity violation in few-body systems [PDF]
Journal of Physics: Conference Series, 2009 Recent interest, both from experimental and theoretical point of view, on hadronic parity violation is reviewed, with particular emphasis on an effective theory description. After discussing the minimal form of the parity-violating NN contact effective Lagrangian, we concentrate on the calculation of the neutron spin rotation in − d scattering at zero

Few-body hypernuclear systems [PDF]
Nuclear Physics A, 1998 Abstract Recent experimental efforts on hypernuclei at KEK and BNL have been extending the research field of baryon many-body systems in the flavor SU(3) world. Regarding Σ-hypernuclei, two recent experiments, E887 and E905, at BNL-AGS have drawn important conclusions concerning the narrow-width problem and the bound-state problem of Σ-hypernuclei ...

Modified interpolation model for few-body systems [PDF]
Ядерна фізика та енергетика, 2009 New modified version of interpolation nuclear model is proposed. Within the scope of this version, the motion equations for pd and ppn systems are derived and the calculations of the corresponding wave functions of these systems and cross-sections of the

Role of relativity and nucleon compositeness in few-body systems [PDF]
, 2000 Recent progress is reviewed in four areas where new experimental data have been obtained: proton-proton bremsstrahlung, threshold pion production in proton-proton collisions, elastic electron-deuteron scattering and deuteron photodisintegration at ...

Quantum Reports, 2022 A method is proposed for describing the dynamics of systems of interacting particles in terms of an auxiliary field, which in the static mode is equivalent to given interatomic potentials, and in the dynamic mode is a classical relativistic composite ...

Spurious states in the Faddeev formalism for few-body systems [PDF]
, 1998 We discuss the appearance of spurious solutions of few-body equations for Faddeev amplitudes. The identification of spurious states, i.e., states that lack the symmetry required for solutions of the Schroedinger equation, as well as the symmetrization of

Nonperturbative Renormalisation Group: Applications to the few and many-body systems
EPJ Web of Conferences, 2010 We consider the applications of functional renormalisation group to few and many-body systems. As an application to the few-body dynamics we study the ratio between the fermion-fermion scattering length and the dimer-dimer scattering length for ...
