The ground-state structure, optical-absorption and photoelectron spectrum of silver clusters
TL;DR: In this article, the most stable structure, optical absorption and photoelectron spectrum of neutral and anionic silver clusters up to 16 atoms have been studied by using particle-swarm optimization technique and density functional theory.

Growth mechanism and electronic and magnetic properties of AgnTi alloy clusters
TL;DR: In this paper, the growth behavior and electronic and magnetic properties of AgnTi (n = 1 -16) clusters have been studied by using density functional theory and unbiased structure prediction method.

Propagation of partially coherent Laguerre Gaussian beams through inhomogeneous turbulent atmosphere
TL;DR: It can be found that the propagation of laser beams in inhomogeneous turbulence is different from that in homogeneous turbulence and it is shown that relative rms spatial widths and M2-factors of PC-ELGBs are more affected by inhomogeneity turbulence than those ofPC-SLGBs.

Propagation based on second-order moments for partially coherent Laguerre–Gaussian beams through atmospheric turbulence
TL;DR: In this article, an analytical formula of the propagation matrixes in terms of the second-order moments of the Wigner distribution function for PCLG Beams in the receiving plane is derived.

Influence of smile effect on beam properties of spectrally combined beams based on diode laser stacks
TL;DR: In this article, a beam propagation model of the external cavity has been further proposed based on the smile model and beam properties such as spectrum, intensity distribution, and beam quality of combined beams have been simulated and discussed.
