Lightning as a natural accelerator of relativistic particles and a source of synchrotron radiation
N. I. Petrov
A physical model of the formation of a vortex current in a plasma channel of lightning discharges due to the anomalous Hall effect caused by relativistic spin-orbit interaction phe…
Modeling of the final jump phase of a positive lightning leader
N. I. Petrov, G. N. Petrova
Behavior of the potential and electric field intensity at the front of a lightning leader channel taking into account the influence of space charges injected by the streamers is in…
Electromagnetic fields created by the lightning leader channel in the final jump phase
N. I. Petrov, G. N. Petrova
The dependences between the parameters of the Lightning discharge in the leader phase and the return stroke phase are obtained. It is shown that the peak values of the electric fie…
Non-invariance of the speed of light in free-space
N. I. Petrov
A plane monochromatic wave propagates in vacuum at the velocity of c. However, wave packets limited in space and time are used to transmit energy and information. Here it has been…
Vector Laguerre-Gauss beams with polarization-OAM entanglement in a graded-index medium
Nikolai I. Petrov
It is shown that the vector-vortex Laguerre-Gauss modes with polarization-orbital angular momentum (OAM) entanglement are the vector solutions of the Maxwell equations in a graded-…
Remote lensless focusing of a light beam
Nikolai I. Petrov
Remote focusing of light in a graded-index medium via mode interference is demonstrated using exact analytical solutions of the wave equation. Strong focusing of light occurs at ex…
Macroscopic quantum effects for classical light
Nikolai I. Petrov
Macroscopic quantum optical effects (Schrodinger cat states, squeezing, collapse and revival) for light beams propagating in an inhomogeneous linear medium are demonstrated using e…
Splitting of levels in a circular dielectric waveguide
Nikolai I. Petrov
A splitting of modes in a circular graded-index optical fiber is demonstrated by solving the full Maxwell equations using the perturbation analysis. It is shown that the degeneracy…
Left-right asymmetry in an optical nanofiber
N. I. Petrov
Symmetry breaking effect for left- and right-handed circularly polarized light beams propagating in a rotationally symmetric graded-index optical fiber is presented. It is shown th…
Reflection and transmission of light at a curved interface: coherent state approach
Nikolai I. Petrov
Phase-space procedure based on coherent state representation is proposed for investigation of reflection and transmission of light beams at a curved dielectric boundary. Numerical…
