We investigate the optical response of gold nanorod (AuNR) dimers assembled in parallel on a DNA origami template. Plasmonic circular dichroism (CD) was found to be highly dependent on the orientation of the dimers relative to the DNA axis and the inter-rod distances. Dipole-dipole distances play a critical role in the induced plasmonic chirality. The orientation dependence of induced CD was fu...

New ab initio surfaces of the potential energies and the induced electric dipole moments of H2–H2 and H2–He collisional complexes are obtained with H2 bond distances from 0.942 to 2.801 bohr. These data permit the calculation of collision-induced absorption (CIA) spectra of dense hydrogen-helium gas mixtures at temperatures up to thousands of kelvin, i.e., under conditions where strong rotovibr...

We derive closed expressions for the Casimir-Polder potential between metal nanoparticles as well as for the light-induced interaction owing to the gradient force. Within the validity of the dipole approximation, the maximum interaction energy turns out to be proportional to the plasma frequency, and it is comparable to the thermal energy at T=300 K. On the other hand, the light-induced interac...

Head model and an efficient method for computing the forward EEG (electroencephalography)problem are essential to dipole source localization(DSL). In this paper, we use less expensive ovoid geometry to approximate human head, aiming at investigating the effects of head shape and dipole source parameters on EEG fields. The application of point least squares (PLS) based on meshless method was int...

The work function (WF) of ZnO is modified by two types of dipole-bearing phenylphosphonate layers, yielding a maximum WF span of 1.2 eV. H3CO-phenyl phosphonate, with a positive dipole (positive pole pointing outwards from the surface), lowers the WF by ∼350 meV. NC-phenyl phosphonate, with a negative dipole, increases the WF by ∼750 meV. The WF shift is found to be independent of the type of Z...

Absorption and luminescence excitation spectra of Xe/CF(4) mixtures were studied in the vacuum UV region at high resolution using tunable synchrotron radiation. Pressure-broadened resonance bands and bands associated with dipole-forbidden states of the Xe atom due to collision-induced breakdown of the optical selection rules are reported. The spectra display in addition numerous satellite bands...

We consider two semi-infinite magnetoelectric media with constant dielectric permittivity separated by a planar interface, whose electromagnetic response is described non-dynamical axion electrodynamics and investigate the radiation of point-like electric dipole located perpendicularly to interface. start from exact Green's function for potential, far-field approximation obtained using modified...

A number of procedures have been employed to decompose recorded scalp potential wave forms into their hypothesized constituent elements. The shortcomings of the various decomposition methods (principal components analysis, topographic components modeling, inverse dipole localization and spatio-temporal dipole modeling) are reviewed and a new dipole components model, which incorporates the stren...

MEG is a useful method to know brain activities, and has a remarkable feature that the source location is estimated with high accuracy. However MEG is insensitive to a radial current dipole, because a radial dipole in a sphere makes no magnetic field outside the sphere and the shape of human head resembles a sphere. To realize more accurate localization, there is a requirement to estimate a rad...

Dirac equation for the finite dipole potential is solved by the method of the join of the asymptotics. The formulas for the near continuum state energy term of a relativistic electron-dipole system are obtained analytically. Two cases are considered: Z < 137 and Z > 137 Dirac equation for Z > 137 is solved by usual method of cut-off potential at small distances.
