Rogue waves in the basin of intermediate depth and the possibility of their formation due to the modulational instabilityPleiades Publishing Ltd - Tập 97 - Trang 194-198 - 2013
I. I. Didenkulova, I. F. Nikolkina, E. N. Pelinovsky
The properties of rogue waves in the basin of intermediate depth are discussed in comparison with known properties of rogue waves in deep waters. Based on observations of rogue waves in the ocean of intermediate depth we demonstrate that the modulational instability can still play a significant role in their formation for basins of 20 m and larger depth. For basins of smaller depth, the influence ...... hiện toàn bộ
On the berry phase in quantum oscillations observed in 3D topological insulatorsPleiades Publishing Ltd - Tập 104 - Trang 864-867 - 2017
S. I. Vedeneev
It is demonstrated that the copper-doped high-quality Bi Se single crystals with a high density of bulk charge carriers are certainly 3D topological insulators. The analysis of quantum Shubnikov−de Haas (SdH) oscillations reveals that these materials simultaneously exhibit two types of such oscillations determined by the Landau levels related to both the 3D and 2D Fermi surfaces.
Multicritical behavior of the phase diagrams of ferromagnet/superconductor layered structuresPleiades Publishing Ltd - Tập 71 - Trang 138-143 - 2000

For ferromagnet/superconductor (F/S) layered structures, new 3D Larkin-Ovchinnikov-Fulde-Ferrell (LOFF) states are predicted. In most cases, these states are characterized by a higher critical temperature T

Multiphoton ionization of atoms by an ultrashort laser pulsePleiades Publishing Ltd - Tập 73 - Trang 1-5 - 2001
V. S. Popov
Closed analytical expressions for the probability of multiphoton ionization of atoms and ions by a time-varying electric field ℰ(t) are obtained by the imaginary time method. These expressions apply for arbitrary values of the Keldysh parameter γ. The dependence of the ionization probability and the photoelectron momentum spectrum on the shape of an ultrashort laser pulse is considered.
Resonance interaction of optical phonons with localized statesPleiades Publishing Ltd - Tập 71 - Trang 155-159 - 2000
L. A. Falkovsky
The optical-phonon Green’s function averaged over the positions of defects—both point and line— is calculated with allowance for possible localized states near the boundary of the continuous spectrum and for their intrinsic damping. The frequency-transfer dependence of the cross section for Raman scattering is calculated with the aid of this Green’s function.
Two models of anisotropic propagation of a cardiac excitation wavePleiades Publishing Ltd - Tập 100 - Trang 351-354 - 2014
I. S. Erofeev, K. I. Agladze
Propagation of the action potential in the real heart is direction-dependent (anisotropic). We propose two general physical models explaining this anisotropy on the cellular level. The first, “delay” model takes into account the frequency of the cell-cell transitions in different directions of propagation, assuming each transition requires some small time interval. The second model relies on the a...... hiện toàn bộ
New Soliton Regime of Generation of Broadband Terahertz Radiation by Laser Pulses with Tilted Wave FrontsPleiades Publishing Ltd - Tập 118 - Trang 408-413 - 2023
S. V. Sazonov, N. V. Ustinov
A new soliton-like regime of generation of terahertz radiation by optical pulses with tilted wave fronts is analyzed. It has been shown that the diffraction of an optical pulse is of fundamental importance for the formation of optical–terahertz soliton. A nonsoliton broadband terahertz component is generated synchronously with the soliton component of radiation. Two matching conditions called “sup...... hiện toàn bộ
