Efficient Approach to Time-Dependent Density-Functional Perturbation Theory for Optical Spectroscopy
Using a superoperator formulation of linearized time-dependent density-functional theory, the dynamical polarizability of a system of interacting electrons is represented by a m...
Metric Signature Transitions in Optical Metamaterials
We demonstrate that the extraordinary waves in indefinite metamaterials experience an (--++) effective metric signature. During a metric signature change transition in such a me...
The Effect of Bilateral Carotid Artery Ligation upon the Blood Flow and the Energy State of the Rat Brain
Abstract The cerebral effects of bilateral carotid artery ligation were studied in ligthly anesthetized rats, either alone or combined with moderate reductions in the mean arter...
Obstacle avoidance using flow field divergence
The use of certain measures of flow field divergence is investigated as a qualitative cue for obstacle avoidance during visual navigation. It is shown that a quantity termed the...
Size distribution and scattering phase function of aerosol particles retrieved from sky brightness measurements
Ground‐based measurements of the solar transmission and sky radiance in a horizontal plane through the Sun are taken in several geographical regions and aerosol types: dust in a...
Bistability and optical switching of spatial patterns in a laser
Bistability of the transverse configuration of the optical field is found for a helium–neon laser oscillating in the TEM01* hybrid optical-resonator mode. Optically induced swit...
Correction of physiologically induced global off‐resonance effects in dynamic echo‐planar and spiral functional imaging
Abstract In functional magnetic resonance imaging, a rapid method such as echo‐planar (EPI) or spiral is used to collect a dynamic series of images. These techniques are sensiti...
Efficient iteration scheme for self-consistent pseudopotential calculations
It is shown that an iteration technique introduced by Manninen et al. for self-consistent jellium-model calculations can be easily extended to provide a simple and very efficien...
Examining Nanoenvironments in Solids on the Scale of a Single, Isolated Impurity Molecule
Optical spectroscopy of single impurity molecules in solids can be used as an exquisitely sensitive probe of the structure and dynamics of the specific local environment around ...
Oscillating Superfluidity of Bosons in Optical Lattices
Following a suggestion by Orzel et al. [Science 291, 2386 (2001)]], we analyze bosons in an optical lattice undergoing a sudden parameter change from the Mott to superfluid phas...
Effect of Chemical Treatment on Electrical Conductivity, Infrared Absorption, and Raman Spectra of Single-Walled Carbon Nanotubes
We investigate the magnitude and temperature dependence of electrical conductivity, the optical and infrared absorption, and the Raman spectra of single-walled carbon nanotube (...
