It has been shown that CP violating electron-nucleon and nucleon-nucleon interactions can induce atomic electric dipole moments and are therefore constrained from experimental data. We show that using the experimental upper bounds on neutron and electron electric dipole moments, one can also obtain constraints, in some cases better ones, on these interactions. In addition stringent constraints ...

phospholipids are important for the biological lipid and are commonly used in biophysical studies.A quantumcalculation for two phospholipids Dipalmitoylphosphatidylethanolamine and dipalmitoylphosphatidic acidwere performed using the abinitio software. Geometry optimization structures were obtained at RHF level using3-21G, 6-31G*. These basis sets were used To understanding the effects of envir...

A rotational isomeric-state model with neighbor dependence is used to calculate mean-square dipole moments and their temperature coefficients for dimethylsiloxane chains (CllajaSi[OSi (CH,).]zOSi (Clla) 3 over a wide range of molecular weight. Chain conformational energies required in the calculations are obtained from a previous analysis of the random-coil dimensions of dimethylsiloxane chains...

Amyloid-forming proteins undergo a structural transition from α-helical to disordered conformations and, ultimately, cross-β fibrils. The unfolding and aggregation of the amyloid β-peptide (Aβ) have been implicated in the development and progression of Alzheimer's disease (AD) and cerebral amyloid angiopathy (CAA). However, the events underlying the initial structural transition leading to the ...

As a further test of the conjectured equivalence of string states and extremal black holes, we compute the dipole moments of black holes with arbitrary spin and superspin in D = 4, N = 4 supergravity coupled to 22 vector multiplets and compare them with the dipole moments of states in the heterotic string on T 6 or the Type IIA string on K3×T . Starting from a purely bosonic black hole with Ker...

We propose, fabricate, and study a double-layer chiral planar metamaterial that exhibits pronounced circular dichroism at near-infrared wavelengths. The antisymmetric oscillation modes of the two coupled layers allow local magnetic-dipole moments and enhanced polarization effects compared with similar single-layer systems where only electric-dipole moments occur. Experiment and rigorous theoret...

We propose to extract the electric and weak dipole moments of the top quark via tt̄γ and tt̄Z productions at the CERN LHC. With the large numbers of events available at the LHC, these dipole moments can be measured to the accuracy of 10e cm. Present mailing address

We present a complete analysis of the electric dipole moment (EDM) of the ρ-meson induced by CP violating operators of dimension 4 and 5 within the QCD sum rules approach. The set of CP-odd operators includes the theta term and the electric and chromoelectric dipole moments of the three light quarks. We find that the ρ-meson EDM induced purely by the EDMs of quarks is smaller, but still in reas...
