Heliograph of the UTR-2 Radio Telescope
Aleksander Stanislavsky, Artem Koval, Aleksander Konovalenko +1
The broadband analog-digital heliograph based on the UTR-2 radio telescope is described in detail. This device operates by employing the parallel-series principle when five equi-sp…
Twist of fractional oscillations
Aleksander Stanislavsky
Using the method of the Laplace transform, we consider fractional oscillations. They are obtained by the time-clock randomization of ordinary harmonic vibrations. In contrast to si…
Fractional dynamics from the ordinary Langevin equation
Aleksander Stanislavsky
We consider the usual Langevin equation depending on an internal time. This parameter is substituted by a first passage time of a self-similar Markov process. Then the Gaussian pro…
The Stochastic Nature of Complexity Evolution in the Fractional Systems
Aleksander Stanislavsky
The stochastic scenario of relaxation in the complex systems is presented. It is based on a general probabilistic formalism of limit theorems. The nonexponential relaxation is show…
Subdiffusive transport in intergranular lanes on the Sun. The Leighton model revisited
Aleksander Stanislavsky, Karina Weron
In this paper we consider a random motion of magnetic bright points (MBP) associated with magnetic fields at the solar photosphere. The MBP transport in the short time range [0-20…
Antenna Performance Analysis for Decameter Solar Radio Observations
Aleksander Stanislavsky, Aleksander Konovalenko, Eduard Abranin +5
Decameter wavelength radio emission is finely structured in solar bursts. For their research it is very important to use a sufficient sensitivity of antenna systems. In this paper…
Long-term memory contribution as applied to the motion of discrete dynamical systems
Aleksander Stanislavsky
We consider the evolution of logistic maps under long-term memory. The memory effects are characterized by one parameter α. If it equals to zero, any memory is absent. This leads t…
Nonlinear reaction with fractional dynamics
Aleksander Stanislavsky
In this paper we consider a system of three fractional differential equations describing a nonlinear reaction. Our analysis includes both analytical technique and numerical simulat…
Two-time scale subordination in physical processes with long-term memory
Aleksander Stanislavsky, Karina Weron
We use the two-time scale subordination in order to describe dynamical processes in continuous media with a long-term memory. Our consideration touches two physical examples in det…
Hamiltonian formalism of fractional systems
Aleksander Stanislavsky
In this paper we consider a generalized classical mechanics with fractional derivatives. The generalization is based on the time-clock randomization of momenta and coordinates take…
Fractional oscillator
Aleksander Stanislavsky
We consider the fractional oscillator being a generalization of the conventional linear oscillator in the framework of fractional calculus. It is interpreted as an ensemble average…
Beam propagation in a Randomly Inhomogeneous Medium
Aleksander Stanislavsky
An integro-differential equation describing the angular distribution of beams is analyzed for a medium with random inhomogeneities. Beams are trapped because inhomogeneities give r…
Subordination scenario of anomalous relaxation
Aleksander Stanislavsky, Karina Weron
The non-exponential relaxation is shown to result from subordination by inverse tempered α-stable processes. The main feature of tempered α-stable processes is a finiteness of thei…
Tempered relaxation with clustering patterns
Aleksander Stanislavsky, Karina Weron
This work is motivated by the relaxation data for materials which exhibit a change of the relationship between the fractional power-law exponents when different relaxation peaks in…
Diffusion and Relaxation Controlled by Tempered α-stable Processes
Aleksander Stanislavsky, Karina Weron, Aleksander Weron
We derive general properties of anomalous diffusion and nonexponential relaxation from the theory of tempered α-stable processes. Its most important application is to overcome the…
Subordination model of anomalous diffusion leading to the two-power-law relaxation responses
Aleksander Stanislavsky, Karina Weron, Justyna Trzmiel
We derive a general pattern of the nonexponential, two-power-law relaxation from the compound subordination theory of random processes applied to anomalous diffusion. The subordina…
Anomalous diffusion. A competition between the very large jumps in physical and operational times
Aleksander Stanislavsky, Karina Weron
In this paper we analyze a coupling between the very large jumps in physical and operational times as applied to anomalous diffusion. The approach is based on subordination of a sk…
Polarization switching and nonreciprocity in symmetric and asymmetric magnetophotonic multilayers with nonlinear defect
Vladimir R. Tuz, Sergei V. Zhukovsky, Sergey L. Prosvirnin
A one-dimensional magnetophotonic crystal with a nonlinear defect placed either symmetrically or asymmetrically inside the structure is considered. Simultaneous effects of time-rev…
A new interpretation of Giant radio pulses from the Crab pulsar
N. Lewandowska, C. Wendel, V. Kondratiev +2
The Crab pulsar experienced a major flare in 2010 as observed by Fermi LAT. Observations by the Hubble Space Telescope indicate that the flare was accompanied by a structural chang…
Enhancement of absorption bistability by trapping light planar metamaterial
Vladimir R. Tuz, Valery S. Butylkin, Sergey L. Prosvirnin
We propose to achieve a strong bistable response of a thin layer of a saturable absorption medium by involving a planar metamaterial specially designed to bear a high-Q trapped-mod…
Relativity, Doppler shifts, and retarded times in deriving the correction for the finite speed of light: a comment on 'Second-order Doppler-shift corrections in free-fall absolute gravimeters'
V D Nagornyi, Y M Zanimonskiy, Y Y Zanimonskiy
In the article (Rothleitner and Francis 2011 Metrologia 48 187-195) the correction due to the finite speed of light in absolute gravimeters is analyzed from the viewpoint of specia…
All-optical switching in metamaterial with high structural symmetry
Vladimir R. Tuz, Sergey L. Prosvirnin
We argue the possibility of realization of a polarization insensitive all-optical switching in a planar metamaterial composed of a 4-fold periodic array of two concentric metal rin…
