MICROSCOPIC CALCULATION OF THE NUCLEAR MEAN FIELD

The Conformations of 1-Thiacyclooctan-3-One Dynamic Nuclear Magnetic Resonance and Force-Field Calculation

The 1H and natural-abundance 13C-NMR spectra of 1-thiacyclooctan-3-one (1) have been measured from 25 to -100°C. Coalescence is observed in the 1H-NMR spectra of (1) at about -80°C, and attributed to ring inversion in a boat-chair conformation, which is the predominant conformation of (1). The free energy of activation (DG¹</s...

A microscopic estimate of the nuclear matter compressibility and symmetry energy in relativistic mean-field models

The relativistic mean-field plus RPA calculations, based on effective Lagrangians with densitydependent meson-nucleon vertex functions, are employed in a microscopic analysis of the nuclear matter compressibility and symmetry energy. We compute the isoscalar monopole and the isovector dipole response of Pb, as well as the differences between the neutron and proton radii for Pb and several Sn is...

Antisymmetrization of a Mean Field Calculation

Microscopic mean-field theory of the jamming transition.

Dense particle packings acquire rigidity through a nonequilibrium jamming transition commonly observed in materials from emulsions to sandpiles. We describe athermal packings and their observed geometric phase transitions by using equilibrium statistical mechanics and develop a fully microscopic, mean-field theory of the jamming transition for soft repulsive spherical particles. We derive analy...

Antisymmetrization of a Mean Field Calculation of the T-matrix

The usual definition of the prior(post) interaction V (V ′) between projectile and target (resp. ejectile and residual target) being contradictory with full antisymmetrization between nucleons, an explicit antisymmetrization projector A must be included in the definition of the transition operator, T ≡ V ′ A + V ′ AGV. We derive the suitably antisym-metrized mean field equations leading to a no...
