Inertial effects in anomalous dielectric relaxation of symmetrical top molecules.
The linear dielectric response of an assembly of noninteracting symmetrical top molecules (each of which is free to rotate in space) is evaluated in the context of fractional dynamics. The infinite hierarchy of differential-recurrence relations for the relaxation functions appropriate to the dielectric response is derived by using the underlying inertial fractional Klein-Kramers equation. On so...
متن کاملSpherical top-hat collapse of a viscous unified dark fluid
In this paper, we test the spherical collapse of a viscous unified dark fluid (VUDF) which has constant adiabatic sound speed and show the nonlinear collapse forVUDF, baryons, and dark matter, which are important in forming the large-scale structure of our Universe. By varying the values of the model parameters α and ζ0, we discuss their effects on the nonlinear collapse of the VUDF model, and ...

متن کاملGeneration of third-order spherical and coma aberrations by use of radically symmetrical fourth-order lenses.
We have extended the method of Alvarez [J. Am. Optom. Assoc. 49, 24 (1978)] to generate a variable magnitude of third-order spherical and/or coma aberration by using a combination of fourth-order plates with a magnification system. The technique, based on the crossed-cylinder aberroscope, is used to measure the wave-front aberration generated by the plates. The method has been applied to correc...
متن کاملT-Matrix light scattering simulation of rough, non-symmetrical spherical particles
Light scattering is an useful tool for the detection and characterization of different types of particles and simulation of the scattering process can help to understand the scattering characteristics. To simplify the computational simulation often axis-symmetric particles are used, while in reality particles usually do not show such simple structures. To cope with this, advanced methods and al...
