Low Density Neutron Star Matter with Quantum Molecular Dynamics: The Role of Isovector Interactions
Universe, 2022 The effect of isospin-dependent nuclear forces on the inner crust of neutron stars is modeled within the framework of Quantum Molecular Dynamics (QMD).

Isospin dependence of the three-nucleon force [PDF]
, 2004 We classify $A$--nucleon forces according to their isospin dependence and discuss the most general isospin structure of the three--nucleon force. We derive the leading and subleading isospin--breaking corrections to the three--nucleon force using the ...

Determination of the stiffness of the nuclear symmetry energy from isospin diffusion [PDF]
, 2004 With an isospin- and momentum-dependent transport model, we find that the degree of isospin diffusion in heavy ion collisions at intermediate energies is affected by both the stiffness of the nuclear symmetry energy and the momentum dependence of the ...

Isospin breaking decays as a diagnosis of the hadronic molecular structure of the Pc(4457) [PDF]
Physical Review D, 2019 The LHCb Collaboration announced the observation of three narrow structures consistent with hidden-charm pentaquark states. They are candidates of hadronic molecules formed of a pair of a charmed baryon and an anticharmed meson.

Classically isospinning Hopf solitons [PDF]
Physical Review D, 2013 We perform full three-dimensional numerical relaxations of isospinning Hopf solitons with Hopf charge up to 8 in the Skyrme-Faddeev model with mass terms included. We explicitly allow the soliton solution to deform and to break the symmetries of the static configuration.

Isospin Conservation in Neutron Rich Systems of Heavy Nuclei
EPJ Web of Conferences, 2018 It is generally believed that isospin would diminish in its importance as we go towards heavy mass region due to isospin mixing caused by the growing Coulomb forces.

Probing Mechanical and Chemical Instabilities in Neutron-Rich Matter [PDF]
, 2001 The isospin-dependence of mechanical and chemical instabilities is investigated within a thermal and nuclear transport model using a Skyrme-type phenomenological equation of state for neutron-rich matter.

ISOSPIN IN FRAGMENT PRODUCTION [PDF]
Theoretical Nuclear Physics in Italy, 2003 Based on a general approach to binary systems we show that in the low density region asymmetric nuclear matter (ANM) is unstable only against isoscalarlike fluctuations. The physical meaning of the thermodynamical chemical and mechanical instabilities is related to the inequality relations verified by the strength of interaction among different ...

The pn interaction and isospin symmetry
Frontiers in PhysicsA possible correlation between isospin symmetry/breaking and the average proton-neutron interaction of the last particles, δVpn, is discussed. This correlation is tested for Tz = ±1/2 mirror nuclei in terms of a differential of δVpn, Δ(δVpn), and their ...

Investigation of Low-Density Symmetry Energy via Nucleon and Fragment Observables
, 2007 With stochastic transport simulations we study in detail central and peripheral collisions at Fermi energies and suggest new observables, sensitive to the symmetry energy below normal density.
