Coherent multiple scattering effects and Monte Carlo method
Pleiades Publishing Ltd - Tập 79 - Trang 109-112 - 2004
Based on the comparison of the iteration procedure of solving the Bethe-Salpeter equation and the Monte Carlo method, we developed a method for simulating coherent multiple-scattering effects within the framework of a unified stochastic approach. The time correlation function and the interference component were calculated for the coherent backscattering from a multiply scattering medium.
Nonplanar contribution to the four-loop universal anomalous dimension of the twist-2 Wilson operators in the $$ \mathcal{N} $$ = 4 supersymmetric Yang-Mills theory
Pleiades Publishing Ltd - Tập 89 - Trang 593-596 - 2009
The result of the direct component calculation of the nonplanar contribution to the four-loop anomalous dimension of the Konishi operator in the
$$
\mathcal{N}
$$
= 4 supersymmetric Yang-Mills theory is reported. The result contains only the ζ(5) term proportional to the ζ(5) contribution in the planar c......
Non-Stationary Spin-Polarized Tunneling through a Quantum Dot Coupled to Noncollinearly Polarized Ferromagnetic Leads
Pleiades Publishing Ltd - Tập 113 - Trang 681-688 - 2021
Non-stationary spin-dependent transport through the interacting single-level quantum dot coupled to ferromagnetic leads with non-collinear magnetizations has been analyzed theoretically. The non-stationary transport is investigated within the theoretical approach based on kinetic equations for the electron occupation numbers with different spins taking into account high order correlation functions......

Unconventional metallic state in a two-dimensional system with broken inversion symmetry
Pleiades Publishing Ltd - Tập 66 - Trang 175-181 - 1997
We present a model that explains two phenomena, recently observed in high-mobility Si-MOS structures: (1) the strong enhancement of metallic conduction at low temperatures, T<2 K, and (2) the occurrence of a metal-insulator transition in the 2D electron system. Both effects are ascribed to the spin-orbit interaction anomalously enhanced by the broken inversion symmetry of the confining potential w......
The strong effect of three-center interactions on the formation of superconductivity with $$d{x^2-y^2}$$ symmetry in the t-J* model
Pleiades Publishing Ltd - Tập 75 - Trang 378-382 - 2002
The effect of three-center interactions on the formation of a superconducting phase with
$$d{x^2-y^2} $$
symmetry is considered using the diagram technique for Hubbard operators and irreducible Green’s functions. It is shown that these interactions lead to a decrease in T

IceCube astrophysical neutrinos without a spectral cutoff and 1015–1017 eV cosmic gamma radiation
Pleiades Publishing Ltd - Tập 100 - Trang 761-765 - 2015
We present a range of unbroken power-law fits to the astrophysical-neutrino spectrum consistent with the most recent published IceCube data at the 68% confidence level. Assuming that the neutrinos originate in decays of π mesons, we estimate accompanying gamma-ray fluxes for various distributions of sources, taking propagation effects into account. We then briefly discuss existing experimental res......
Rogue waves in the basin of intermediate depth and the possibility of their formation due to the modulational instability
Pleiades Publishing Ltd - Tập 97 - Trang 194-198 - 2013
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 ......
Surface electron scattering in d-wave superconductors
Pleiades Publishing Ltd - Tập 69 - Trang 262-267 - 1999
A theoretical model of a rough surface in a d-wave superconductor is studied for the general case of arbitrary strength of electron scattering by an impurity layer covering the surface. Boundary conditions for quasiclassical Eilenberger equations are derived at the interface between the impurity layer and the d-wave superconductor. The model is applied to the self-consistent calculation of the sur......
Nonresonant Excitation of a Magnon Bose–Einstein Condensate in MnCO3
Pleiades Publishing Ltd - Tập 109 - Trang 40-44 - 2019
Coupled nuclear–electron precession in MnCO3 under nonresonant excitation is studied. The experimental results clearly confirm the formation of a magnon Bose–Einstein condensate. The empirical relations describing the formation of such condensate are found.
