Abstract This paper presents the background, scientific objectives, experimental design, and preliminary achievements of Third Tibetan Plateau (TP) Atmospheric Scientific Experiment (TIPEX-III) for 8–10 years. It began in 2013 has expanded plateau-scale observation networks by adding stations data-scarce areas; executed integrated missions land surface, planetary boundary layer, cloud–precipitation, troposphere–stratosphere exchange processes coordinating ground-based, air-based, satellite...
The Tibetan Plateau (TP) is a key area affecting forecasts of weather and climate in China occurrences extreme events over the world. Meteorological Administration, National Natural Science Foundation China, Chinese Academy Sciences jointly initiated Third Atmospheric Experiment (TIPEX-III) 2013, with an 8–10-yr implementation plan. Since its preliminary field measurements conducted routine automatic sounding systems have been deployed at Shiquanhe, Gaize, Shenzha stations western TP, where...

Based Fourier transformation Bessel-Gaussian (BGVB) generated through combination spiral phase plate axicon, at 1064 nm with topological charge (TC) up to 6 created. By SHG these PVBs MgO-doped, periodically poled congruent LiNbO3 crystal, green wavelength (532 nm) TCs 12 are generated. TC PVB identified by...
Tetragonal Mn-Pt-Sn Heusler compounds have been of interest because they enable magnetic antiskyrmion phases, which can potentially lead to low energy cost spintronic device applications. We report the synthesis and systematic study transport properties magnetron sputtered tetragonal Mn2PtSn thin films on thermally oxidized Si substrates. observed a large topological Hall resistivity up 0.57 μΩ cm around 150 K, is largest value among Mn-based metallic materials so far. Moreover, effect (THE)...

Atmospheric sounding observations from May to September 2015 2019 16 sites were used for...
We report a systematic study of the magnetic and transport properties magnetron sputtered nonchiral hexagonal MnNiGa films on thermally oxidized Si substrates as function film thickness. A large topological Hall effect (THE) is observed, its magnitude increases correspondingly with increasing The THE appears in very wide temperature range 10 K–300 K field region where field-dependent resistivity largely deviates from magnetization. Moreover, measurements cubic do not show any evidence...
We study the ground-state phases of a two-dimensional rotating spin-orbit coupled spin-1/2 Bose-Einstein condensates with constant interaction and spatially modulated nonlinear interaction, respectively. By comparing not only promotes realization phase but also protects stability vortex line structure. Under action we find that number vortices in every layer along azimuthal direction successively increases as rotational frequency enhances, are uniformed distributed around center. The diagram...
It is now widely believed that $p$-wave superfluidity the key to generate a novel critical phase in non-Abelian Aubry-Andr\'e-Harper model. However, we here establish this belief incorrect. In work, systemically investigate transition of quasiperiodic mosaic lattice model with superfluidity. The results show exists only model, whereas despite presence superfluidity, absent, and mobility edge (ME) phases are generated instead. Furthermore, if period modulation...
We have experimentally created perfect vortex beams (PVBs) by Fourier transformation of Bessel–Gaussian beams, which are generated modulating the fundamental Gaussian beam with spiral phase plates and axicons, respectively. Although method has been used many times other authors, as far we know, few people pay attention to quantitative relationship between control parameters PVB ring width. The effects waist radius wg, base angle axicon γ, focal length lens f on spot (ring ρ, half-width Δ)...
In this work, we demonstrate a Watt-level, high-quality Laguerre–Gaussian (LG) LG0±1 vortex mode directly output from an end-pumped Nd:YVO4 laser by using axicon-based annular pump beam.

We report on a systematical study of the structure, magnetism, and magnetotransport behavior hexagonal MnNiGa films deposited thermally oxidized Si (001) substrates by magnetron sputtering. X-ray diffractions reveal that all at different temperatures crystallized in Ni2In-type structure (space group P63/mmc). Scanning electron microscopy observations show surface morphology varies with deposition temperature, energy dispersive spectroscopy analysis shows compositions remain nearly unchanged,...
A realistic simulation of rainfall over the Tibetan Plateau (TP) is a big challenge for both regional and global climate models.
