Local Nucleon-Nucleon and Three-Nucleon Interactions Within Chiral Effective Field Theory [PDF]
Frontiers in Physics, 2020 To obtain an understanding of the structure and reactions of nuclear systems from first principles has been a long-standing goal of nuclear physics. In this respect, few- and many-body systems provide a unique laboratory for studying nuclear interactions.

Core-valence absorption in breakup and stripping reactions and its isospin dependence [PDF]
EPJ Web of Conferences, 2023 In this work, the effect of nucleon-core absorption on nucleon removal reaction is explored through the use of complex nucleon-core interactions. Results are presented for exclusive breakup reactions, where absorption is explored through the use of a ...

Four-body Faddeev-type calculation of the K̅NNN system [PDF]
EPJ Web of Conferences, 2022 A quasi-bound state in the K̅NNN system caused by strong interactions was studied using dynamically exact four-body Faddeev-type equations. Binding energy and width of the K−ppn state were calculated using three antikaon-nucleon and three nucleon-nucleon

Two-dimensional three-body quadrupole-quadrupole interactions [PDF]
, 2021 Similar to interactions between dipoles, or van der Waals interactions, quadrupole-quadrupole interactions are interactions between quadrupoles. In this article, we study the quadrupole interactions between highly excited atoms or Rydberg atoms. In addition, unlike many other calculations, in which the primary focus was on the one-dimensional two-body ...

Uncertainties in ab initio nuclear structure calculations with chiral interactions
Frontiers in Physics, 2023 We present theoretical ground state energies and their uncertainties for p-shell nuclei obtained from chiral effective field theory internucleon interactions as a function of chiral order, fitted to two- and three-body data only.

DeepSI: Interactive Deep Learning for Semantic Interaction [PDF]
IUI '21: 26th International Conference on Intelligent User
Interfaces, College Station, TX, USA, April 2021, 2023 In this paper, we design novel interactive deep learning methods to improve semantic interactions in visual analytics applications. The ability of semantic interaction to infer analysts' precise intents during sensemaking is dependent on the quality of the underlying data representation.

Transferable Interactiveness Knowledge for Human-Object Interaction Detection [PDF]
IEEE Transactions on Pattern Analysis and Machine Intelligence,
2021, 2021 Human-Object Interaction (HOI) detection is an important problem to understand how humans interact with objects. In this paper, we explore interactiveness knowledge which indicates whether a human and an object interact with each other or not. We found that interactiveness knowledge can be learned across HOI datasets and bridge the gap between diverse ...

Nucleon-nucleon potential from skyrmion dipole interactions
Nuclear Physics B, 2021 We derive the nucleon-nucleon interaction from the Skyrme model using second order perturbation theory and the dipole approximation to skyrmion dynamics. Unlike previous derivations, our derivation accounts for the non-trivial kinetic and potential parts
