The optical and electrical properties of the molecules pyrimethamine and sulfadoxine in gas phase and in different mediums (water and ethanol) were calculated using density-functional theory at the B3LYP level and the Restricted Hartree–Fock (RHF)

We show a technique for external direct current (DC) control of the amplitudes of limit cycles both in the Phase-shift and Twin-T oscillators. We have found that amplitudes of the oscillator output voltage depend on the DC control voltage. By varying

In this paper, we present global minimum energy for iron clusters, ranging from sizes N = 2 to 100 atoms, described by the phenomenological Gupta potential. Our optimized structures and symmetry groups are in agreement with previous ones obtained usi

We investigate the effect of plasmon screening on the polaron characteristics following the Feynman variational method and find that the screening considerably reduces the polaron characteristics, as plasmon density increases. We establish that the f

In this paper, we analyze the synchronization of two chaotic electronic devices that are described by a jerk equation and apply it to chaos masking of communications. Both the theoretical and experimental investigations are carried out and we find go

We establish that the screening due to plasmons reduces the effective electron-phonon coupling in the nanocrystal appreciably, and that the contribution of the self-action potential energy to the polaron ground state energy reduces with increasing pl

Bipolaron states in a quasi-0D quantum dot with a spherical parabolic confinement potential are investigated by applying the Feynman variational principle. The bipolaron coupling energy and self-action potential energy are found to increase with an i

By varying the coupling strength, clusters synchronization is found in a ring of four mutually coupled semiconductor lasers with optical feedback. The numerical simulation confirms the mathematical analysis and shows the degree of synchronization in

This paper studies the dynamics of a self-excited oscillator with two external periodic forces. Both the nonresonant and resonant states of the oscillator are considered. The hysteresis boundaries are derived and the hysteresis domains are defined in
