The nuclear quadrupole moment of In has been determined by combining the experimental nuclear quadrupole coupling constants and electric field gradients, calculated at the four-component CCSD~T! level of theory, of four indium halides. Our recommended value for the nuclear quadrupole moment of In is 770~8! millibarn. A basis set study at the Dirac–Hartree–Fock level shows a slow convergence of ...

We show that, in valence quark models, the relativistic corrections to the SU(6) relation for the contribution of the electric dipole moments of the quarks to the electric dipole moment of the neutron can be expressed as a multiplicative correction factor. The correction factor is evaluated in light cone wavefunction models, in the bag model, and in relativistic mean-eld models, and is found to...

We study the quantum properties of Rydberg atoms in a magnetic Ioffe-Pritchard trap which is superimposed by a homogeneous electric field. Trapped Rydberg atoms can be created in long-lived electronic states exhibiting a permanent electric dipole moment of several hundred Debye. The resulting dipole-dipole interaction in conjunction with the radial confinement is demonstrated to give rise to an...

We propose using matrix-isolated paramagnetic diatomic molecules to search for the electric dipole moment of the electron (eEDM). As was suggested by Shapiro in 1968, the eEDM leads to a magnetization of a sample in the external electric field. In a typical condensed matter experiment, the effective field on the unpaired electron is of the same order of magnitude as the laboratory field, typica...

This paper deals with the Quincke rotation of small insulating particles. This dc electrorotation of insulating objects immersed in a slightly conducting liquid is usually explained by looking at the action of the free charges present in the liquid. Under the effect of the dc electric field, the charges accumulate at the surface of the insulating particle which, in turn, acquires a dipole momen...
