The formation of a response with a pronounced maximum and an excitation pulse symmetric with respect to the end time is determined when a coherent signal is input to the input of the system, which is a mirror image of the impulse response. The correlation coefficient between the left and right parts of the response was chosen as a criterion for.

Get this from a library. Dielectric response and electron correlation. [A P G Kutty; P G Khubchandani; India. Atomic Energy Commission.]. The dielectric function (this term will be used in this chapter; other terms frequently used in literature being dielectric permittivity and dielectric constant) ε*(ω) describes the response of a material to the application of an alternating electric field E(ω).For small electric field strengths a linear relationship holds between E and polarization P.

Nearly all materials are dielectrics, that is they do not exhibit a direct-current (DC) conductivity on the macroscopic scale, but instead act as an electrical capacitance i.

e., they store measurement of the dielectric response is noninvasive and has been used for material characterisation throughout most of the 20th century, and consequently a number of books already exist that.

The dielectric function of a charged Bose gas is determined from the response to an imposed static sinusoidal electric field. Variational and diffusion quantum Monte Carlo simulations are used to calculate the ground-state properties of the system with trial wave functions containing a parameter dependent on the amplitude and wavelength of the perturbation.

We discuss the dielectric response of a crystal. We consider separately the ionic response and the electronic response in the Random Phase Approximation. We then consider explicitly the interesting limits of the response of an electron gas in three and two dimensions at low temperature, and in the static- and long-wavelength by: 2.

From the theoretical point of view, more sophisticated treatments of the homogeneous electron gas model evolved, including dynamical aspects of the electron correlation in the dielectric response.

Furthermore, the homogeneous electron gas, which served as a model for simple metals, was extended to include spin- and charge-density waves and : Springer US.

The response function (inverse dielectric function) for an electron gas in an external magnetic field is investigated by the method of Green's functions using the random phase approximation.

The grain size effect in sintered CaTiO 3 samples was prominent, notably in dielectric responses above ~1 MHz. Increase in sintering temperature remarkably led to an enhancement in dielectric constant values and reduction in dielectric loss values. Therefore, a significant correlation existed between microstructural features and dielectric.

Ramprasad, N. Shi, and C. Tang Introduction Phenomena such as charge conduction, dielectric response, and dielectric degradation or breakdown are the result of complex processes operating at multiple temporal and spatial scales. Electron energy loss spectroscopy of MgH 2 in the plasmon energy range is reported here as a part of a study to determine the dielectric function of this hydride.

From the dielectric function, we have estimated the unperturbed plasmon energy of MgH 2 as eV. Interband transitions are also inferred from the dielectric by: 6.
