Cluster emission under femtosecond laser ablation of silicon

open access: yes, 2003
Rich populations of clusters have been observed after femtosecond laser ablation of bulk silicon in vacuum. Size and velocity distributions of the clusters as well as their charge states have been analyzed by reflectron time-of-flight mass spectrometry ...

To the sources of the motive of mass psychosis in M.A. Bulgakov’s novel “The Master and Margarita”

open access: yesНеофилология, 2022
The aim of the work is to analyze the motive of mass psychosis in the novel “Master and Margarita” by M.A. Bulgakov. It is relevant nowadays, when the tendency of close study of madness motive in the writer's works as a particular case of madness motive ...

Bound States in the Continuum and Fano Resonances in the Dirac Cone Spectrum

open access: yes, 2019
We consider light scattering by two dimensional arrays of high-index dielectric spheres arranged into the triangular lattice. It is demonstrated that in the case a triple degeneracy of resonant leaky modes in the Gamma-point the scattering spectra ...

CALCULATION OF THREE-LAYER BEAMS BY THE FINITE ELEMENT-METHOD WITH THE HELP OF LIRA PC

open access: yesВестник Дагестанского государственного технического университета: Технические науки, 2016
. Currently very popular among engineers and scientists are the software systems, which are based on the finite element method (FEM).The basic concept of the finite element method is a direct discretization of the calculated system that is divided by the

Silicon clusters produced by femtosecond laser ablation: Non-thermal emission and gas-phase condensation

open access: yes, 2004
Neutral silicon clusters Si_n (up to n = 7) and their cations Si_n+ (up to n = 10) have been produced by femtosecond laser ablation of bulk silicon in vacuum and investigated using time-of-flight mass spectrometry.

Bound states in the continuum in open acoustic resonators

open access: yes, 2015
We consider bound states in the continuum (BSC) or embedded trapped modes in two- and three-dimensional acoustic axisymmetric duct-cavity structures. We demonstrate numerically that under variation of the length of the cavity multiple BSCs occur due to ...

Topological phase transitions in tilted optical lattices [PDF]

open access: yes, 2018
We analyze the energy spectrum and eigenstates of cold atoms in a tilted brick-wall optical lattice. When the tilt is applied, the system exhibits a sequence of topological phase transitions reflected in an abrupt change of the eigenstates.
