The scenario of single particle (proton as well as neutron) states near the Fermi surface of 132Sn has been investigated on the basis of an average one-body potential suitably optimised for 208Pb and then extrapolated to the mass region concerned. The calculation shows excellent agreement with experiment. The ground state charge distribution of the nucleus has also been calculated.

13C and 1H spectra have been determined for 18 4-substituted phenylacetylenes and carbon charge densities have been estimated by CNDO/2 molecular orbital calculations. Correlations of these parameters with σ1, and σR0 indicate that the important mechanisms of transmission of substituent effects are field, resonance, and π polarization effects, as previously noted for 4-substituted styrenes. Evidence is presented that demonstrates that both 1H and 13C chemical shifts for these compounds reflect ground state charge densities. CNDO/2 calculations on a variety of aromatic derivatives suggest that the σ1, dependence of 19F chemical shifts in these derivatives may primarily be due to π polarization.

Abstract As a sequel to previous work, we extend the study of the ground state configuration of the D = 3, Wilson-Fisher conformal O(4) model. In this work, we prove that for generic ratios of two charge densities, ρ1/ρ2, the ground-state configuration is inhomogeneous and that the inhomogeneity expresses itself towards longer spatial periods. This is the direct extension of the similar statements we previously made for ρ1/ρ2 ≪ 1. We also compute, at fixed set of charges, ρ1, ρ2, the ground state energy and the two-point function(s) associated with this inhomogeneous configuration on the torus. The ground state energy was found to scale (ρ1 + ρ2)3/2, as dictated by dimensional analysis and similarly to the case of the O(2) model. Unlike the case of the O(2) model, the ground also strongly violates cluster decomposition in the large-volume, fixed-density limit, with a two-point function that is negative definite at antipodal points of the torus at leading order at large charge.

Ground state charge of some fermion soliton system without C-invariance is calculated in 1+1 and 3+1 dimensions by a combination of adiabatic method and spectral flow analysis. Induced charge is calculated by evolving adiabatically the fields from a vacuum having a background field which has a zero energy state and spectral symmetry. The spectral flow is calculated by an analysis of the bound state spectrum. In 1+1 dimension our calculations are in agreement with the results already found in the literature. In 3+1 dimension we study the interaction of fermions with monopoles and dyons. In the case of monopoles, even though there is spectral asymmetry, ground state charge is found to be ±1/2. It is shown that ground state charge gets contribution only from the lowest angular momentum states and is discontinuous at the fermion mass.
