Dielectric anisotropy in the GW space-time method
Excited-state calculations, notably for quasiparticle band structures, are nowadays routinely performed within the GW approximation for the electronic self-energy. Nevertheless, certain numerical approximations and simplifications are still employed in practice to make the computations feasible. An important aspect for periodic systems is the proper treatment of the singularity of the screened ...
متن کاملSpacetime anisotropy affects cosmological entanglement
Most existing cosmological entanglement studies are focused on the isotropic Robertson-Walker (RW) spacetime. Here we go beyond this limitation and study the influence of anisotropy on entanglement generated by dynamical spacetime. Since the isotropic spacetime is viewed as a background medium and the anisotropy is incorporated as perturbation, we decompose entanglement entropy into isotropic a...
متن کاملDielectric Studies of a Substance with Negative Dielectric Anisotropy
The results of dielectric studies of 6BAP(F) (l-[4-(hexylbicyclo[2,2,2]octyl]-2-(3-fluoro-4-methoxyphenyl)ethane) in the nematic and isotropic phases are presented. The substance has a negative dielectric anisotropy. By applying two experimental techniques, using a network analyzer and time domain spectrometer (TDS), the two main relaxation processes, connected with the molecular reorientation ...
متن کاملThe dielectric behaviour of single-shell spherical cells with a dielectric anisotropy in the shell
Recent experiments on cells treated with hydrophobic ions showed that the mobile charges adsorbed to the plasma membrane contributed significantly to the low-frequency dielectric behaviour of cells. Due to the different transport properties of the mobile ions along the radial and tangential directions within the membrane, there is a dielectric anisotropy in the plasma membrane. In this work, we...
متن کاملAnisotropy and interplane interactions in the dielectric response of graphite.
We determined the anisotropic dielectric response of graphite by means of time-dependent density-functional theory and high-resolution valence electron energy-loss spectroscopy. The calculated loss function was in very good agreement with the experiment for a wide range of momentum-transfer orientations with respect to the graphitic basal planes, provided that local-field effects were included ...
