Two-dimensional Bi₂Se₃ nanosheets with hexagonal shape are synthesized by a solution synthetic route. The Bi₂Se₃ nanosheets are 120 nm in edge width and 7 nm in thickness. The size of the Bi₂Se₃ nanosheets can be controlled by choosing different kinds of reducing agents including hydroxylamine and ethylenediamine. Subsequently, we demonstrate a configuration of two-color all-optical switching b...

The third-order nonlinear Schrodinger equation (alias the Hirota equation) is investigated via deep leaning neural networks, which describes strongly dispersive ion-acoustic wave in plasma and propagation of ultrashort light pulses optical fibers, as well broader-banded waves on water. In this paper, we use physics-informed networks (PINNs) learning method to explore data-driven solutions (e.g....

LLE Review, Volume 80 191 The filamentation instability causes local intensity maxima in a laser beam propagating through a plasma to self-focus to high intensities. This process can affect many aspects of the beam propagation and absorption, so it has long been a subject of interest in laser–plasma interaction research. The theoretical thresholds and growth rates for the linear phase of the fi...

Radiation propagating over cosmological distances can probe light weakly interacting pseudoscalar (or scalar) particles. The existence of a spin-0 field changes the dynamical symmetries of electrodynamics. It predicts spontaneous generation of polarization of electromagnetic waves due to mode mixing in the presence of background magnetic field. We illustrate this by calculations of propagation ...

objective: nowadays light-cured composites are used widely by orthodontists to bond brackets. as these composites require 20-40 seconds time per tooth to be light cured, more chair-time in needed compared to self-cured composites. in recent years, the argon laser and plasma arc lights have been introduced in dentistry to reduce this curing time. the purpose of this study was to compare bond str...
