Depolarization effects in the human eye
Vision Research, 2001 We have studied the effects of depolarization in the living human eye by using a spatially resolved Mueller-matrix polarimeter [Opt. Lett. 24 (1999) 64].

Molecular Physics, 1985
Abstract Polarizabilities, like multipole moments, are commonly ascribed to the molecule as a whole, but they describe movements of charge density within the molecule, and are often associated with particular regions. The polarizabilitiesdescribe changes in the charge distribution arising from external fields, and a single-centre ...

Polarizability of a hydrogenic state
Physical Review A, 1996Using Floquet spectroscopy, we have measured the scalar and tensor polarizabilities of a nominally hydrogenic state of a multielectron atom. We obtain ${\mathrm{\ensuremath{\alpha}}}_{0}$=426.1\ifmmode\pm\else\textpm\fi{}16 MHz/(V/cm${)}^{2}$ and ${\mathrm{\ensuremath{\alpha}}}_{2}$=-66.3\ifmmode\pm\else\textpm\fi{}22 MHz/(V/${\mathrm{cm}}^{2}$) for ...

Polarizability of alkali clusters
Physical Review B, 1985Molecular-beam deflection measurements of the static electric polarizability per atom, \ensuremath{\alpha}/N, are reported for sodium clusters up to N=40. The quantity \ensuremath{\alpha}/N decreases from the atomic polarizability to approximately 150% of the bulk value, at N=40.

Core Polarizabilities in Metals
Physica Scripta, 1982Linear response formalism within the density-functional scheme is applied in a calculation of core polarizabilities in simple metals. While the core polarizability changes relatively little (around 10%) from its free-ion value in the alkalis, Mg and Al, large increases are found for metals like Ga, Cd, In, and Sn with full d-shells.

Hydrodynamics of Polarizable Liquids
Annals of Physics, 1993The complete hydrodynamic theory of polarizable and magnetizable isotropic liquids is presented. Using only input of universal acceptance, the Lorentz transformation, the macroscopic Maxwell equations, and the thermodynamics, a set of hydrodynamic equations of motion is derived rigorously, without any ad-hoc assumptions or residual ambiguities ...

Magnetic Polarizability of the Electron
Nature, 1949THE anomaly of the magnetic moment of the electron has been explained by Schwinger1 as due to the interaction of the electron with the zero-point fluctuations of the radiation field. A particularly simple derivation has recently been given by Luttinger2. Luttinger considers the state of an electron in a constant magnetic field H such that its energy is

X Polarizabilities and hyperpolarizabilities
2009This chapter presents and discusses recent achievements towards determining and interpreting polarizabilities and hyperpolarizabilities of atoms, molecules, clusters, supramolecular assemblies, polymers, and aggregates. It evidences both the strong activities in the field and their dual character.

On the role of polarizability in QSAR
Bioorganic & Medicinal Chemistry, 2005The polarizability of a molecule, an important physical property, is currently attracting our attention particularly in the area of QSAR for chemical-biological interactions. In this report, the polarizability effects on ligand-substrate interactions has been discussed in terms of NVE (number of valence electrons) using additive values for valence ...

The Simulation of Solvent Polarizabilities and Dipolarities with Polarizable Continuum Model
The Journal of Physical Chemistry BThe ability of polarizable continuum models (PCM) to simulate nonspecific solvent effects (dipolarity and polarizability) was evaluated by calculating the transition energies of 1,1,10,10-tetrabutyldecanonaene (ttbp9) and 2-N,N-dimethylamino-7-nitrofluorene (DMANF), basis of Catalán's polarizability (SP) and dipolarity (SdP) solvent scales ...
