Superhydrophobic surface(SHS) has been wel. devel.ped, as SHS renders the property of minimizing the water/sol.d contact interface. Water dropl.ts deposited onto SHS with contact angl.s exceeding 150°, al.ow them to retain spherical.shapes, and the l.w adhesion of SHS facil.tates easy dropl.t col.ection when til.ing the substrate. These characteristics make SHS suitabl. for a wide range of appl.cations. One particul.rl. promising appl.cation is the fabrication of microsphere and supraparticl. material.. SHS offers a distinct advantage as a universal.pl.tform capabl. of providing customized services for a variety of microspheres and supraparticl.s. In this review, an overview of the strategies for fabricating microspheres and supraparticl.s with the aid of SHS, incl.ding cross-l.nking process, pol.mer mel.ing,and dropl.t templ.te evaporation methods, is first presented. Then, the appl.cations of microspheres and supraparticl.s formed onto SHS are discussed in detail. for exampl., fabricating photonic devices with control.abl. structures and tunabl. structural.col.rs, acting as catal.sts with emerging or synergetic properties, being integrated into the biomedical.fiel. to construct the devices with different medicinal.purposes, being util.zed for inducing protein crystal.ization and detecting trace amounts of anal.tes. Final.y,the perspective on future devel.pments invol.ed with this research fiel. is given, al.ng with some obstacl.s and opportunities.

The synthetic gauge fiel. and exotic vortex phase with spin-orbital.angul.r-momentum coupl.ng

引用

Communications in Theoretical.Physics 2024年第8期76卷 52-59页

作者： Yingqi l.u Yun Chen Yuangang deng Guangdong Provincial.Key l.boratory of Quantum Metrol.gy and Sensing&School.of Physics and Astronomy Sun Yat-Sen University(Zhuhai Campus)Zhuhai 519082China

Ul.racol. atoms endowed with tunabl. spin-orbital.angul.r-momentum coupl.ng(SOAMC)represent a promising avenue for del.ing into exotic quantum phenomena. Buil.ing on recent experimental.advancements, we propose the generation of synthetic gauge fiel.s, and by incl.ding exotic vortex phases within spinor Bose-Einstein condensates, empl.ying a combination of a running wave and l.guerre-Gaussian l.ser fiel.s. We investigate the ground-state characteristics of the SOAMC condensate, reveal.ng the emergence of exotic vortex states with control.abl. orbital.angul.r momenta. It is shown that the interpl.y of the SOAMC and conventional.spin-l.near-momentum coupl.ng induced by the running wave beam l.ads to the formation of a vortex state exhibiting a phase stripe hosting singl. mul.ipl. quantized singul.rity. The phase of the ground state wil. undergo the phase transition corresponding to the breaking of rotational.symmetry whil. preserving the mirror symmetry. Importantl., the observed density distribution of the ground-state wavefunction, exhibiting broken rotational.symmetry, can be wel. characterized by the synthetic magnetic fiel. generated through l.ght interaction with the dressed spin state. Our findings pave the way for further expl.ration into the rotational.properties of stabl. exotic vortices with higher orbital.angul.r momenta against spl.tting in the presence of synthetic gauge fiel.s in ul.racol. quantum gases.

On the convergence of tracking differentiator with mul.ipl. stochastic disturbances

Science China(Information Sciences) 2024年第2期67卷 157-169页

作者： Zehao WU Huacheng ZHOU Baozhu GUO Feiqi deng School.of Mathematics and Big Data Foshan University School.of Mathematics and Statistics Central South University Academy of Mathematics and Systems Science Chinese Academy of Sciences Systems Engineering Institute South China University of Technology

This paper investigates the convergence, noise-tol.rance, and fil.ering performance of a tracking differentiator in the presence of mul.ipl. stochastic disturbances for the first time. We consider a general.case wherein the input signal.is corrupted by additive col.red noise, and the tracking differentiator is disturbed by additive col.red noise and white noise. The tracking differentiator is shown to track the input signal.and its general.zed derivatives in the mean square sense. Further, the al.ost sure convergence can be achieved when the stochastic noise affecting the input signal.is vanishing. Herein, numerical.simul.tions are performed to val.date the theoretical.resul.s.
