Generation and annihilation of scalar particles due to a curved expanding and contracting space-time
While a theory calculating a cosmological generation of particles ina case of the expanding space-time is quite developed, we study here a theory of a cosmological generation of particles in a case of a space- time which is expanding and then contrac

Static dielectric susceptibility for the paraelectric phase of a particle was calculated exactly. Temperature and diameter dependence are described analytically. There are two regimes of the susceptibility: for temperatures above the bulk critical fe

There exists nonhomogeneous structure in mechanosynthesized nanoparticles consisting of an ordered core surrounded by the shell. The shell may be structurally and magnetically disordered, or it may be ordered. These nanoparticles are found to be roug

In this paper, we study the behavior of the particle in the paraelectric phase near the bulk critical temperature (a = 0) (in our units) and near the particle critical temperature (ad) using the fluctuation–dissipation theorem through the power spe

The dielectric dynamic susceptibility of a particle is studied numerically using the exact susceptibility expression in other to understand particle physical properties. There exist one peak in the imaginary part and two peaks in the real part of the

We study the Cole–Cole diagram for the case of a paraelectric particle for which the relaxation time is the same for every mode and the resonance frequency changes and there is an infinite number of such modes. We will calculate the Cole–Cole dia
