In this paper, we consider the Zitterbewegung (ZB) effect for Klein-Gordon particles induced by a cosmic string, near which curvature effects play a dominant role. An analytical expression for the current is obtained and analyzed.
We obtain the Maxwell`s equations used the supersymmetric action based on the actions for the scalar and spinor fields, which are built on the invariants of the electromagnetic field. We analyze the pulse instability in the framework of nonlinear electrodynamics without the approximation of slowly varying amplitudes and phases. We observe the collapse of an extremely short pulse. Within the framework of the Schwinger mechanism, the creation of scalar and spin particles is estimated.
It was found that the spontaneous electric field can occur in doped graphene in an external dc electric field. The direction of the spontaneous field is perpendicular to the applied field. This effect can be connected with the nonequilibrium electron subsystem of graphene. It was also shown up the influence of problem parameters on the characteristics of the spontaneous field.
The system of equations describing an ultrashort optical pulses propagation in semiconductor superlattice with applied magnetic field was obtained based on Boltzmann equation in the relaxation-time approximation for the single electron distribution function and coupled Maxwell equations for the electromagnetic field. It was demonstrated that an original linear-polarized optical pulse initiates an orthogonal polarization in the field of a sample. The propagation dynamics of initiated and initial pulses in the sample was investigated. The effects of the lattice geometry have been elicited.
Propagation of the alternating electromagnetic field in a system of zigzag carbon nanotubes in the case of low temperatures and applied external electric fields are considered. The electronic system of the carbon nanotubes is investigated microscopically nonmetering an interaction with a phonon subsystem by the fact that the electromagnetic pulse is critically short. An efficient equation for the vector-potential amplitude of the alternating electromagnetic field is obtained. Solutions of solitons analogs which correspond to solitons in the case of cosine dispersion law for the electronic subsystem have been elicited. The dependences of obtained nonlinear solutions on problem parameters and the applied external electric fields were analyzed. The possibility to control the shape of optical pulse in wide range was shown.
We calculate the current density in a semiconductor superlattice with parabolic miniband under crossed non-quantizing electric and magnetic fields. The Corbino disk geometry is considered. The current-voltage curve contains oscillations with period proportional to the magnetic field. The possibility is shown of the negative absolute conductivity. The Ampere-Gauss characteristics also contain overshoots under high enough electric fields. In all cases, the peaks smear with temperature rising.
We represent the results of quantum chemical calculations of boron nitride nanotubes intercalated by alkali and alkali-earth metall atoms and its ions. It was obtained that unpair spins were localized on seperated metal atoms. So we propose to construct the two-qubit cells on the basis of infilled boron nitride nanotubes for the quantum computer.
