using hartree-fock su-sheriffer-heeger (hf-ssh) model, we have studied the dependence of the energies of the ground (magnetic triplet state) and the first exited (nonmagnetic singlet state) states of the size-2 trigonal zigzag graphene nanoflake (size-2 nf) on the intensity of an external in plane static electric field at zero temperature. we identify a transition from the magnetic triplet stat...

The mean-field dynamics of an electric dipole moment in a deterministic and a fluctuating electric field is solved to obtain the average over fluctuations of the dipole moment and the angular momentum as a function of time for a Gaussian white-noise stochastic electric field. The components of the average electric dipole moment and the average angular momentum along the deterministic electric-f...

the ultraviolet-visible (uv) spectra of toluene, ortho-bromo and para-bromo toluene in different solvents have been studied. the electric dipole moments and polarizabilities in the molecular excited electronic states were determined. it was found that the electric dipole moments for the excited states (µ*) and the ground states (µ) of these compounds are equal, and the change in dipole moment i...

We present a theoretical study of electrorotation (ER) of two spherical particles under the action of a rotating electric field. When the two particles approach and finally touch, the mutual polarization interaction between the particles leads to a change in the dipole moment of the individual particle and hence the ER spectrum, as compared to that of the well-separated particles. The mutual po...

Field Due to an Electric Dipole An electric dipole consists of two particles with charges of equal magnitude q but opposite sign, separated by a small distance d. Their electric dipole moment has magnitude qd and points from the negative charge to the positive charge. The magnitude of the electric field set up by the dipole at a distant point on the dipole axis (which runs through both charges) is

The result of a search for the electric dipole moment of the neutron is presented. A short review of past experimental work and theoretical predictions introduces a discussion of the experimental method used in, and the results obtained by, the present work. The weighted mean of three separate groups of data gives (+0.4 + 1.5) X 10 "cm for the neutron's electric dipole moment. We conclude that ...

The metastable H ∆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) [1]. 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 magnetic moment μH = 8.5(5) × 10−3 μB displays the predict...

The electric dipole moment of the muon (dμ) is evaluated in a two Higgs doublet model with a softly broken discrete symmetry. For tan β ≡ |v2|/|v1| ∼ 1, contributions from two loop diagrams involving the t quark and the W boson dominate; while for tan β ∼ > 10, contributions from two loop diagrams involving the b quark and the τ lepton are dominant. For 8 ∼ > tan β ∼ > 4, significant cancellati...
