Quantum correlations and spatial localization in trapped one-dimensional ultra-cold Bose–Bose–Bose mixtures

open access: yesNew Journal of Physics
We systematically investigate and illustrate the complete ground-state phase diagram for a one-dimensional, three-species mixture of a few repulsively interacting bosons trapped harmonically.

Effective Josephson dynamics in resonantly driven Bose–Einstein condensates

open access: yesNew Journal of Physics, 2013
We show that the orbital Josephson effect appears in a wide range of driven atomic Bose–Einstein condensed systems, including quantum ratchets, double wells and box potentials. We use three separate numerical methods: the Gross–Pitaevskii equation, exact

On the Appearance of Families of Efimov States in the Spinor Three-Body Problem

open access: yesEPJ Web of Conferences, 2016
Few-body systems with access to multiple internal levels exhibit richness beyond that typically found in their single-level counterparts. One example is that of Efimov states in strongly-correlated spinor three-body systems. In [V. E. Colussi, C.

Rescattering effects in the reaction γd → π − pp

open access: yesScientific Reports
Experimental data for the tensor analyzing power $$T_{20}$$ in the $$\gamma d \rightarrow \pi ^{-} p p$$ reaction were obtained in the photon energy range from 400 to 650 MeV, with the proton momenta in the laboratory system exceeding 400 MeV/c. The data

Adaptive propagation of quantum few-body systems with time-dependent Hamiltonians [PDF]

open access: yes, 2013
In this study, a variety of methods are tested and compared for the numerical solution of the Schr\"odinger equation for few-body systems with explicitely time-dependent Hamiltonians, with the aim to find the optimal one.

Parallel Implementation of Numerical Solution of Few-Body Problem Using Feynman’s Continual Integrals

open access: yesEPJ Web of Conferences, 2018
Modern parallel computing algorithm has been applied to the solution of the few-body problem. The approach is based on Feynman’s continual integrals method implemented in C++ programming language using NVIDIA CUDA technology. A wide range of 3-body and 4-

Relativistic treatment of the few body system

open access: yesNuclear Physics A, 1985
Some specific examples of effects of mesonic degrees of freedom and special relativity in the two- and three-nucleon system are reviewed. For the twonucleon system a relativistic covariant formulation of the one boson exchange and isobar model is described based on the Bethe-Salpeter equation.

Few-body neutron and kaonic clusters

open access: yesPhysical Sciences and Technology, 2017
In this review, we try to summarize the results of experimental search and theoretical studies within variational methods, the method of Faddeev and Faddeev-Yakubovsky equations, and the method of hyperspherical harmonics for the lightest neutron and ...

POLARIZATION PHENOMENA IN FEW-BODY SYSTEMS [PDF]

open access: yes, 1976
Recent polarization studies in N--N scattering at and below 50 MeV have provided specific and significant improvements in the phase-shift parameters. High energy investigations with both polarized proton beams and targets have shown unexpectedly large spin effects, and this provides a challenge for theoretical effort to explain these results ...

Symmetry breaking-induced N-body electrodynamic forces in optical matter systems

open access: yesNature Communications
Breaking symmetry can give rise to non-reciprocal forces–unequal and opposite forces–typically observed in active matter systems involving asymmetric 2-body interactions.
