Device for the Field Measurements of Frequency-Dependent Soil Properties in the Frequency Range of Lightning Currents
Dmitry Kuklin
Existing approaches for the field measurements of the frequency-dependent soil properties take a significant amount of time, making it difficult to obtain new experimental data and…
Atom ionization by ultrashort laser pulse - 2D, 3D consideration
Nikolay V. Larionov, Dmitry N. Makarov, Alexander A. Smirnovsky
We theoretically analyze the quantum vortices - the zeros of electron wave function which are formed through atom ionization by ultrashort laser pulse. In 2D space we consider the…
Optical-mechanical cooling of a charged resonator
Dmitry N Makarov
One of the most effective methods for cooling micro and nano devices to ultra low temperatures is the sideband method. Currently, this approach is being studied experimentally and…
Invariants for Laplacians on periodic graphs
E. Korotyaev, N. Saburova
We consider a Laplacian on periodic discrete graphs. Its spectrum consists of a finite number of bands. In a class of periodic 1-forms, i.e., functions defined on edges of the peri…
New-Type Internal Target for Structural Ion Stripping
D. N. Makarov, V. I. Matveev
The search is now on for, new materials that can be used for ionic stripping. Materials that maximize the stripping of the structural ion are important for conducting experiments w…
Coupled harmonic oscillators and their quantum entanglement
Dmitry Makarov
A system of two coupled quantum harmonic oscillators with the Hamiltonian ${\hat H}=\frac{1}{2}\left(\frac{1}{m_1}{\hat p}^{2}_1 + \frac{1}{m_2}{\hat p}^{2}_2+A x^2_1+B x^2_2+ C x_…
Spectral estimates for Schrödinger operators on periodic discrete graphs
E. Korotyaev, N. Saburova
We consider normalized Laplacians and their perturbations by periodic potentials (Schrödinger operators) on periodic discrete graphs. The spectrum of the operators consists of an a…
Quantum dynamics of a hydrogen-like atom in a time-dependent box: non-adiabatic regime
S. Rakhmanov, D. Matrasulov, V. I. Matveev
We consider a hydrogen atom confined in time-dependent trap created by a spherical impenetrable box with time-dependent radius. For such model we study the behavior of atomic elect…
Laplacians on periodic graphs with guides
Evgeny Korotyaev, Natalia Saburova
We consider Laplace operators on periodic discrete graphs perturbed by guides, i.e., graphs which are periodic in some directions and finite in other ones. The spectrum of the Lapl…
High intensity generation of entangled photons in a two-mode electromagnetic field
D. N. Makarov
At present, the sources of entangled photons have a low rate of photon generation. This limitation is a key component of quantum informatics for the realization of such functions a…
Deficiency numbers of operators generated by infinite Jacobi matrices
I. N. Braeutigam, K. A. Mirzoev
Let be matrices, whose elements are complex numbers, are selfadjoint matrices and exist. We study the deficiency index prob…
Scattering on periodic metric graphs
Evgeny Korotyaev, Natalia Saburova
We consider the Laplacian on a periodic metric graph and obtain its decomposition into a direct fiber integral in terms of the corresponding discrete Laplacian. Eigenfunctions and…
Stability analysis of a model gene network links aging, stress resistance, and negligible senescence
Valeria Kogan, Ivan Molodtcov, Leonid I. Menshikov +2
Several animal species are considered to exhibit what is called negligible senescence, i.e. they do not show signs of functional decline or any increase of mortality with age, and…
Estimates of bands for Laplacians on periodic equilateral metric graphs
Evgeny Korotyaev, Natalia Saburova
We consider Laplacians on periodic equilateral metric graphs. The spectrum of the Laplacian consists of an absolutely continuous part (which is a union of an infinite number of non…
Universality of the Berezinskii-Kosterlitz-Thouless type of phase transition in the dipolar XY-model
A. Yu. Vasiliev, A. E. Tarkhov, L. I. Menshikov +2
We investigate the nature of the phase transition occurring in a planar XY-model spin system with dipole-dipole interactions. It is demonstrated that a Berezinskii-Kosterlitz-Thoul…
Polarization Bremsstrahlung in collissions of fast ions with multiatomic targets
M. Ya. Amusia, V. I. Matveev
We consider the processes of polarization bremsstrahlung in collisions of fast ions with linear chains consisting of isolated atoms. We obtained intensities and angular distributio…
