Zitterbewegung and symmetry switching in Klein's four-group
L. Chotorlishvili, P. Ziȩba I. Tralle, A. Ugulava
Zitterbewegung is the exotic phenomenon associated either with the relativistic electron-positron rapid oscillation or to the electron-hole transitions in the narrow gap semiconduc…
Magnetization of superparamagnetics in the state of mechanical anisotropy
Archil Ugulava, Simon Chkhaidze, Shalva Kekutia +1
The internal energy of magnetic anisotropy for some nanoparticles dominates over the thermal energy even at room temperature. Strong magnetic anisotropy of nanoparticles can signif…
Nonlinear dynamics of two coupled nano-electromechanical resonators
L. Chotorlishvili, A. Ugulava, G. Mchedlishvili +3
As a model of coupled nano-electromechanical resonantors we study two nonlinear driven oscillators with an arbitrary coupling strength between them. Analytical expressions are deri…
Self-Chaotization in Coupled Optical Waveguides
Ramaz Khomeriki, Archil Ugulava, Levan Chotorlishvili
We consider theoretically two coupled optical waveguides with a varying barrier height along the waveguides direction. The barrier could be constructed by the elongated island with…
Quantum chaos and its kinetic stage of evolution
L. Chotorlishvili, A. Ugulava
Usually reason of irreversibility in open quantum-mechanical system is interaction with a thermal bath, consisting form infinite number of degrees of freedom. Irreversibility in th…
Paul Trap and the Problem of Quantum Stability
L. Chotorlishvili, K. Nickoladze, G. Mchedlishvili
This work is devoted to the investigation of possibility of controlling of ions motion inside Paul trap. It has been shown that by proper selection of the parameters of controlling…
