The effect of relativity on the properties of the interhalogens ClF, BrF, BrCl, IF, IBr, and IBr is studied by comparing relativistic and nonrelativistic calculations. Bond lengths, harmonic frequencies, and dissociation energies show that the bond is weakened in the relativistic formalism. Relativity increases the electric dipole moment whereas the electric quadrupole moment and dipole polariz...

The metastable H 3 1 state in the thorium monoxide (ThO) molecule is highly sensitive to the presence of a CP-violating permanent electric dipole moment of the electron (eEDM) [E. R. Meyer and J. L. Bohn, Phys. Rev. A 78, 010502 (2008)]. The magnetic dipole moment μH and the molecule-fixed electric dipole moment DH of this state are measured in preparation for a search for the eEDM. The small m...

We examine the time-reversal-violating nuclear ‘‘Schiff moment’’ that induces electric dipole moments in atoms. After presenting a self-contained derivation of the form of the Schiff operator, we show that the distribution of Schiff strength, an important ingredient in the ground-state Schiff moment, is very different from the electric-dipole-strength distribution, with the Schiff moment receiv...

We present the quantum computation of nuclear observables where operators interest are first decomposed in terms linear combination unitaries. Then we utilise Hadamard test and unitaries (LCU) based methods to compute expectation values. apply these calculate electric quadrupole moment deuteron. The results compared for Jordan-Wigner transformation Gray code encoding. discuss versatility our ap...

We study the effects of model-dependent contributions and the electric quadrupole moment of vector mesons in the decays V − → PP 0γ and τ → νV γ. Their interference with the amplitude originating from the radiation due to electric charges vanishes for photons emitted collinearly to the charged particle in the final state. This brings further support to our claim in previous works, that measurem...

The growth rate and maximum value of electric field inside the thundercloud of finite dimensions are calculated incorporating the effect of positive space charge produced by corona at the ground surface. Our theoretical findings reveal that the transport of corona space charge increases significantly electric dipole moment already existing in thunderclouds of moderate heights and is partly resp...

The structures, energetics, and transition states of water clusters (trimer to pentamer, n = 3-5) are investigated as a function of electric field by using ab initio calculations. With an increasing strength of the field, the most stable cyclic structures of trimer, tetramer, and pentamer open up to align their dipole moments along the direction of the field. For the lower strength (below 0.3 V...

We develop a theory of electric-field-induced magnetization of a medium. The relevant polarizability, βCP , simultaneously violates the inversion symmetry (parity), the time-reversal symmetry, and the combined CP symmetry. We focus on two fundamental mechanisms mediating the appearance of βCP — the electric dipole moment of the electron (eEDM) and the electron-nucleus pseudo-scalar weak neutral...

I show that the electric dipole moment of the W-boson dW vanishes to two loop order in the standard Kobayashi-Maskawa Model of CP violation. The argument is a simple generalization of that used to show the vanishing of the quark electric dipole moment. As a consequence, the electron electric dipole moment vanishes to three loop order. Including QCD corrections may give a non-vanishing result; I...
