The equations of state of spin-polarized nuclear matter and pure neutron matter are studied in the framework of the Brueckner-Hartree-Fock theory including a three-body force. The energy per nucleon EA(δ) calculated in the full range of spin polarization δ = ρ↑−ρ↓ ρ for symmetric nuclear matter and pure neutron matter fulfills a parabolic law. In both cases the spin-symmetry energy is calculate...
متن کاملCan spin-polarized photoemission measure spin properties in condensed matter?
Photoemitted electrons move in a vacuum; their quantum state can be completely characterized in terms of energy, momentum and spin polarization by spin-polarized photoemission experiments. A review article in this issue by Heinzmann and Dil (2012 J. Phys.: Condens. Matter 24 173001) considers whether the measured spin properties, i.e. the magnitude and direction of the spin polarization vector,...
متن کاملSpin-asymmetry energy of nuclear matter
We calculate the density-dependent spin-asymmetry energy S(kf ) of isospin-symmetric nuclear matter in the three-loop approximation of chiral perturbation theory. The interaction contributions to S(kf ) originate from one-pion exchange, iterated one-pion exchange, and (irreducible) two-pion exchange with no, single, and double virtual ∆-isobar excitation. We find that the truncation to 1π-excha...
متن کاملSpin-isospin stability of nuclear matter
We calculate the density-dependent spin-isospin asymmetry energy J(kf ) of nuclear matter in the three-loop approximation of chiral perturbation theory. The interaction contributions to J(kf ) originate from one-pion exchange, iterated one-pion exchange, and irreducible two-pion exchange with no, single, and double virtual ∆-isobar excitation. We find that the approximation to 1π-exchange and i...
متن کاملAn Entanglement Study of Superposition of Qutrit Spin-Coherent States
Considering generalized concurrence as the criterion of entanglement, we study entanglement properties of superposition of two qutrit coherent states, as a function of their amplitudes. These states may attain maximum entanglement or no entanglement at all, depending on the choice of the parameters involved. The states revealing maximum entanglement also display the maximum violations of the Be...
