Optical Remote Sensing Potentials for Looting Detection

Geosciences, 2017
Looting of archaeological sites is illegal and considered a major anthropogenic threat for cultural heritage, entailing undesirable and irreversible damage at several levels, such as landscape disturbance, heritage destruction, and adverse social impact.

Theory of spin-polarized optical potential

Journal of Synchrotron Radiation, 2001
We develop an approximation for the non-local spin-polarized optical potential theory for atoms in solids at intermediate and high energy. The present approximation for the optical potential builds on the GW-expression. We separate the RPA polarization propagator into a core electron and a valence electron part, and can then achieve a corresponding ...

Ultrasensitive label-free optical recording of bioelectric potentials using dioxythiophene-based electrochromic polymers

Nature Communications
Dioxythiophene-based polymers are electrochromic, effectively converting electric potentials into optical signals through voltage-dependent changes in absorption.

The optical potential for light weakly bound deuteron-like particles subbarrier elastic scattering [PDF]

Ядерна фізика та енергетика, 2007
The analytical expression for the optical potential of light weakly bound deuteron-like particles subbarrier elastic scattering in the electric field of heavy nuclei have been obtained and the calculations of these potentials for deuteron and 6He ions ...

Instantaneous modulations in time-varying complex optical potentials

New Journal of Physics, 2017
We study the impact of a spatially homogeneous yet non-stationary dielectric permittivity on the dynamical and spectral properties of light. Our choice of potential is motivated by the interest in ${ \mathcal P }{ \mathcal T }$ -symmetric systems as an ...

Optical-model potential and RPA in the continuum [PDF]

Zeitschrift f�r Physik, 1971
The optical-model potential for nucleon-nucleus scattering is constructed theoretically in the framework of the RPA. Inelastic channels and resonant states contributions to the imaginary part differ from the TDA case. The origin of this difference is qualitatively discussed. A small background term is added to the real part.

Prediction of reaction cross section for p-Cr

EPJ Web of Conferences, 2016
Nuclear matter densities and charge radii for even 46−62Cr isotopes have been calculated using relativistic Hartree-Bogoliubov model based on density-dependent meson-exchange relativistic energy density functional.

Forced Atom Interferometers in Optical Harmonic Potentials

Atoms
We present a study of Doppler-sensitive light-pulse atom interferometers operating within optical dipole potentials, where atomic trajectories are manipulated using momentum transfer from light pulses and optical forces from the trap.

Comments on the energy-independent optical potential

Physics Letters B, 1983
Abstract It is noted that the energy-independent optical potential yields both scattering and bound state solutions, and that this potential must be asymmetric to yield a spectroscopic factor different from unity.
