Shear viscosity of neutron matter from realistic nucleon-nucleon interactions. [PDF]
Physical Review Letters, 2007 The calculation of transport properties of Fermi liquids, based on the formalism developed by Abrikosov and Khalatnikov, requires the knowledge of the probability of collisions between quasiparticles in the vicinity of the Fermi surface.

Optimizing higher-order network topology for synchronization of coupled phase oscillators [PDF]
arXiv, 2021 Networks in nature have complex interactions among agents. One significant phenomenon induced by interactions is synchronization of coupled agents, and the interactive network topology can be tuned to optimize synchronization. The previous studies showed that the optimized conventional network with pairwise interactions favors a homogeneous degree ...

An optimized chiral nucleon-nucleon interaction at next-to-next-to-leading order [PDF]
, 2013 We optimize the nucleon-nucleon interaction from chiral effective field theory at next-to-next- to-leading order. The resulting new chiral force NNLOopt yields \chi^2 \approx 1 per degree of freedom for laboratory energies below approximately 125 MeV. In

Physics Letters B, 2023 Nucleon decays put extremely stringent bounds on baryon-number-violating interactions. However, in case the corresponding operators involve only τ leptons, the direct two-body decays, e.g., p→π0τ+, are kinematically not allowed and nucleon decay can only

Pauli Exclusion Classical Potential for Intermediate-Energy Heavy-Ion Collisions
Universe, 2023 This article presents a classical potential used to describe nucleon–nucleon interactions at intermediate energies. The potential depends on the relative momentum of the colliding nucleons and can be used to describe interactions at low momentum transfer

Semi-realistic nucleon-nucleon interactions with improved neutron-matter properties [PDF]
, 2012 New parameter-sets of the semi-realistic nucleon-nucleon interaction are developed, by modifying the M3Y interaction but maintaining the tensor channels and the longest-range central channels.

Antinucleon-nucleon interaction in chiral effective field theory [PDF]
, 2013 Results of an exploratory study of the antinucleon-nucleon interaction within chiral effective field theory are reported. The antinucleon-nucleon potential is derived up to next-to-next-to-leading order, based on a modified Weinberg power counting, in ...

The cross section minima in elastic Nd scattering: a ``smoking gun'' for three nucleon force effects [PDF]
, 1998 Neutron-deuteron elastic scattering cross sections are calculated at different energies using modern nucleon-nucleon interactions and the Tucson-Melbourne three-nucleon force adjusted to the triton binding energy.

Formal theory of heavy ion double charge exchange reactions [PDF]
EPJ Web of ConferencesThe theory of heavy ion double charge exchange (DCE) reactions A(Z, N) → A(Z ± 2, N ∓ 2) is recapitulated emphasizing the role of Double Single Charge Exchange (DSCE) and pion-nucleon Majorana DCE (MDCE) reactions.
