Antinucleon-nucleon interaction in chiral effective field theory
EPJ Web of Conferences, 2018 A study of the antinucleon-nucleon interaction within chiral effective theory is presented. This novel approach suggested by Weinberg for investigating nucleon-nucleon interaction can be adapted straightforwardly to the antinucleon-system.

Collective multipole excitations based on correlated realistic nucleon-nucleon interactions [PDF]
, 2006 We investigate collective multipole excitations for closed-shell nuclei from $^{16}\mathrm{O}$ to $^{208}\mathrm{Pb}$ by using correlated realistic nucleon-nucleon interactions in the framework of the random phase approximation (RPA).

Charge dependent calculations of single particle energies in nuclei around O-16 with modern nucleon nucleon interactions [PDF]
, 2003 The binding energies of the ground states and several excited states related to single-particle and -hole states in nuclei around $^{16}\mathrm{O}$ are calculated taking charge dependence into account.

Charge dependence of the nucleon-nucleon interaction [PDF]
Physical Review C, 1998 Based upon the Bonn meson-exchange-model for the nucleon-nucleon ($NN$) interaction, we calculate the charge-independence breaking (CIB) of the $NN$ interaction due to pion-mass splitting. Besides the one-pion-exchange (OPE), we take into account the $2 $-exchange model and contributions from three and four irreducible pion exchanges. We calculate the

EPJ Web of Conferences, 2010 We review on a novel chiral power counting scheme for in-medium chiral perturbation theory with nucleons and pions as degrees of freedom. It allows for a systematic expansion taking into account local as well as pion-mediated inter-nucleon ...

Four-nucleon force in chiral effective field theory [PDF]
, 2005 We derive the leading contribution to the four-nucleon force within the framework of chiral effective field theory. It is governed by the exchange of pions and the lowest-order nucleon-nucleon contact interaction and includes effects due to the nonlinear

Chiral 2N and 3N interactions and quantum Monte Carlo applications
EPJ Web of Conferences, 2016 Chiral Effective Field Theory (EFT) two- and three-nucleon forces are now widely employed. Since they were originally formulated in momentum space, these interactions were non-local, making them inaccessible to Quantum Monte Carlo (QMC) methods.

Multi-Relation Aware Temporal Interaction Network Embedding [PDF]
arXiv, 2021 Temporal interaction networks are formed in many fields, e.g., e-commerce, online education, and social network service. Temporal interaction network embedding can effectively mine the information in temporal interaction networks, which is of great significance to the above fields.

Charge asymmetry of the nucleon-nucleon interaction [PDF]
Physical Review C, 1998 Based upon the Bonn meson-exchange model for the nucleon-nucleon ($NN$) interaction, we study systematically the charge-symmetry-breaking (CSB) of the $NN$ interaction due to nucleon mass splitting. Particular attention is payed to CSB generated by the $2 $-exchange contribution to the $NN$ interaction, $ $ diagrams, and other multi-meson-exchanges.

Eta Prime Gluonic Contribution to the Nucleon Self-Energy in an Effective Theory
Advances in High Energy Physics, 2014 We estimate a possible η′ gluonic contribution to the self-energy of a nucleon in an effective theory. The couplings of the topological charge density to nucleons give rise to OZI violating η′-nucleon interactions.
