Four-Body Bound State Formulation in Three-Dimensional Approach (Without Angular Momentum Decomposition) [PDF]

open access: yes, 2006
The four-body bound state with two-body forces is formulated by the Three-Dimensional approach, which greatly simplifies the numerical calculations of few-body systems without performing the Partial Wave components.

Description of Four- and Five-Nucleon Systems by Solving Faddeev-Yakubovsky Equations in Configuration Space

open access: yesFrontiers in Physics, 2020
The Faddeev-Yakubovsky equations constitute a rigorous formulation of the quantum mechanical N-body problem in the framework of non-relativistic dynamics.

Electromagnetic reactions of few-body systems with the Lorentz integral transform method [PDF]

open access: yes, 2007
Various electromagnetic few-body break-up reactions into the many-body continuum are calculated microscopically with the Lorentz integral transform (LIT) method.

Few-Body States in Fermi-Systems and Condensation Phenomena

open access: yes, 1999
Residual interactions in many particle systems lead to strong correlations. A multitude of spectacular phenomenae in many particle systems are connected to correlation effects in such systems, e.g. pairing, superconductivity, superfluidity, Bose-Einstein

Relativistic Theory of Few-Body Systems [PDF]

open access: yes, 2002
Very significant advances have been made in the relativistic theory of few body systems since I visited Peter Sauer and his group in Hannover in 1983. This talk provides an opportunity to review the progress in this field since then.

Universality in few-body systems [PDF]

open access: yes, 2018
We explore ground state properties of quantum few-body systems which consist of one, two or three different atom species. Stability of different clusters consisting of spin-polarized hydrogen, helium, neon, argon, alkali and alkaline earth isotopes is determined and their structure is analyzed.

Exactly solvable quantum few-body systems associated with the symmetries of the three-dimensional and four-dimensional icosahedra

open access: yesSciPost Physics, 2016
The purpose of this article is to demonstrate that non-crystallographic reflection groups can be used to build new solvable quantum particle systems. We explicitly construct a one-parametric family of solvable four-body systems on a line, related to ...

Universality in few-body systems with large scattering length

open access: yes, 2005
Effective Field Theory (EFT) provides a powerful framework that exploits a separation of scales in physical systems to perform systematically improvable, model-independent calculations.

Uncertainty quantification in electromagnetic observables of nuclei

open access: yesFrontiers in Physics, 2023
We present strategies to quantify theoretical uncertainties in modern ab initio calculations of electromagnetic observables in light and medium-mass nuclei. We discuss how uncertainties build up from various sources, such as the approximations introduced

Antikaon-nucleon dynamics and its application to few-body systems

open access: yes, 2012
We overview the recent progress in the investigation of the antikaon dynamics with single nucleon and with few-body nuclei, based on chiral SU(3) symmetry.
