It is well known that supersymmetric models allow new sources for CP violation that arise from soft supersymmetry breaking terms. If unsuppressed, these new CP-violating phases would give too large a neutron electric dipole moment. We discuss a mechanism for suppressing SUSY phases in stringinspired supergravity models in which supersymmetry is assumed to be broken by the auxiliary components o...

We suggest the binding of neutral atoms to a current carrying wire through the interaction between the atomic magnetic dipole moment and the wire's magnetic field. The theoretical description is based upon an extension of the concept of supersymmetry to multicomponent wave functions. A solution for spin 2 particles is obtained directly in coordinate space. Spin 1 particles are considered as wel...

We developed an equation of state (EOS) by Ihm, Song, and Mason (ISM) for polar fluids. The model consists of four parameters, namely, the second virial coefficient, an effective van der Waals co-volume, a scaling factor, and the reduced dipole moment. The second virial coefficient is calculated from a correlation that uses the heat of vaporization, and the liquid density at the normal boiling ...

Water exists in two spin isomers, ortho and para, that have different nuclear spin states. In bulk water, rapid proton exchange and hindered molecular rotation obscure the direct observation of two spin isomers. The supramolecular endofullerene H2O@C60 provides freely rotating, isolated water molecules even at cryogenic temperatures. Here we show that the bulk dielectric constant of this substa...

We calculate perturbatively the effect of a dipolar interaction upon the Bose-Einstein condensation temperature. This dipolar shift depends on the angle between the symmetry axes of the trap and the aligned atomic dipole moments, and is extremal for parallel or orthogonal orientations, respectively. The difference of both critical temperatures exhibits most clearly the dipole-dipole interaction...

The anomalous chromomagnetic dipole moment of the top quark in different frameworks and using the b → sγ process Abstract The anomalous chromomagnetic top quark moment arise from one loop corrections to the vertex ¯ ttg. We give explicit formulae for this anomalous coupling in the framework of the standard model, the two higgs doublet model and the minimal supersymmetric standard model. Finally...

Ab initio calculations at the level of CASPT2 with Dunning's correlation consistent cc-pVXZ (X=D, T, Q) basis sets have been carried out for pyrimidine, quinoxaline, phthalazine, and their substituted compounds to find candidates that show a change in the direction of the electric dipole moment for the S(0)-->S(1) transition. The present calculations reveal that 6,7-difluorophthalazine and 6,7-...

The crystal structure of the title compound, C(31)H(26)N(4)O(4), displays a trans conformation for the nitro-phenyl-diazenyl portion of the mol-ecule. Packing diagrams indicate that weak C-H⋯O hydrogen bonds, likely associated with a strong dipole moment present in the mol-ecule, dictate the arrangement of mol-ecules in the crystal structure.

The Standard Model of particle physics is known to be incomplete. Extensions to the Standard Model, such as weak-scale supersymmetry, posit the existence of new particles and interactions that are asymmetric under time reversal (T) and nearly always predict a small yet potentially measurable electron electric dipole moment (EDM), d(e), in the range of 10(-27) to 10(-30) e·cm. The EDM is an asym...

The energetics of water molecules in proteins is studied using the water placement software Dowser. We compared the water position predictions for 14 high-resolution crystal structures of oligopeptide-binding protein (OppA) containing a large number of resolved internal water molecules. From the analysis of the outputs of Dowser with variable parameters and comparison with experimental X-ray da...
