7Collective radiance of giant atoms in non-Markovian regime显示文摘We investigate the non-Markovian dynamics of two giant artificial atoms interacting with a continuum of bosonic modes in a onedimensional(1D) waveguide.Based on the diagrammatic method,we present the exact analytical solutions,which predict the rich phenomena of collective radiance.For the certain collective states,the decay rates are found to be far beyond that predicted in the the Dicke model and standard Markovian framework,which indicates the occurrence of super-superradiance.The superadiance-to-subradiance transition could be realized by adjusting the exchange symmetry of giant atoms.Moreover,there exist multiple bound states in continuum(BICs),with photons/phonons bouncing back and forth in the cavity-like geometries formed by the coupling points.The trapped photons/phonons in the BICs can also be re-released conveniently by changing the energy level splitting of giant atoms.The mechanism relies on the joint effects of the coherent time-delayed feedback and the interference between the coupling points of giant atoms.This work fundamentally broadens the fields of giant atom collective radiance by introducing non-Markovianity.It also paves the way for a clean analytical description of the nonlinear open quantum system with more complex retardation.Qing-Yang Qiu Ying Wu Xin-You Lü 2023Science China(Physics,Mechanics & Astronomy)2023,66,2:0
8Extraction of vanadium from vanadium slag by high pressure oxidative acid leaching显示文摘To extract vanadium in an environment friendly manner,this study focuses on the process of leaching vanadium from vanadium slag by high pressure oxidative acid leaching.Characterizations of the raw slag,mineralogy transformation,and the form of leach residues were made by X-ray diffraction,scanning electron microscopy,and energy dispersive X-ray spectroscopy.The result shows that the vanadium slag is composed of major phases of fayalite,titanomagnetite,and spinel.During the high pressure oxidative acid leaching process,the fayalite and spinel phases are gradually decomposed by sulfuric acid,causing the release of vanadium and iron in the solution.Meanwhile,unreacted silicon and titanium are enriched in the leach residues.With the initial concentration of sulfuric acid at 250 g·L^(-1),a leaching temperature of 140℃,a leaching time of 50 min,a liquid-solid ratio of 10:1 mL·g^(-1),and oxygen pressure at 0.2 MPa,the leaching rate of vanadium reaches 97.69%.Guo-quan Zhang Ting-an Zhang Guo-zhi Lü Ying Zhang Yan Liu Zhuo-lin Liu 2015International Journal of Minerals,Metallurgy and Materials2015,22,1:9
9High responsivity 4H-SiC based metal-semiconductor-metal ultraviolet photodetectors显示文摘4H-SiC based metal-semiconductor-metal (MSM) photodetectors with diverse spacing were designed, fabricated, and characterized, in which nickel Schottky contacts were needed. Current-voltage and spectral responsivity measurements were carried out at room temperature. The fabricated 4 μm-spacing device showed a very low dark current (0.25 pA at 5 V bias voltage), a typical responsivity of 0.103 A/W at 20 V, and a peak re-sponse wavelength at 290 nm. The fabricated devices held a high DUV to visible re-jection ratio of >103.YANG WeiFeng ZHANG Feng LIU ZhuGuang LüYing WU ZhengYun 2008Science China(Physics,Mechanics & Astronomy)2008,51,11:4
10Spacelike Mobius Hypersurfaces in Four Dimensional Lorentzian Space Form显示文摘In this paper, we first set up an alternative fundamental theory of M?bius geometry for any umbilic-free spacelike hypersurfaces in four dimensional Lorentzian space form, and prove the hypersurfaces can be determined completely by a system consisting of a function W and a tangent frame {E_i}. Then we give a complete classification for spacelike M?bius homogeneous hypersurfaces in four dimensional Lorentzian space form. They are either M?bius equivalent to spacelike Dupin hypersurfaces or to some cylinders constructed from logarithmic curves and hyperbolic logarithmic spirals. Some of them have parallel para-Blaschke tensors with non-vanishing M?bius form.Yan Bin LIN Ying Lü Chang Ping WANG 2019Acta Mathematica Sinica,English Series2019,35,4:4
11Effect of Tongxieyaofang decoction on colonic mucosal protein expression profiles in rats with visceral hypersensitivity显示文摘OBJECTIVE: To explore the underlying mechanism of action of Tongxieyaofang decoction in rats with visceral hypersensitivity using proteomics technology.METHODS: Twenty-four female Sprague-Dawley rats were randomly divided into three groups: control group, irritable bowel syndrome(IBS) group and Tongxieyaofang treatment group. An IBS model, characterized as visceral hypersensitivity, was established using the odour of mothballs as conditional stimulation and colorectal distension combined with classic physical restraint as non-conditional stimulation. Rats were intragastrically treated with Tongxieyaofang(2 or 4 m L · kg^(-1)· d^(-1))for 4 weeks. On the 45 th day, the rats were dissected and the colonic mucosal proteins were extracted. Differential protein spots were screened by fluorescent two-dimensional differential gel electrophoresis(2 D-DIGE), and identified by matrix-assisted laser desorption/ionisation time of flight mass spectrometry(MALDI-TOF-MS). Western blotting experiments were performed to verify the changes observed in 2 D-DIGE and MALDI-TOF-MS.RESULTS: It was found that the visceral sensitivity of rats in the Tongxieyaofang treatment group(4 m L/kg) was lower than that in the IBS group(P <0.01). Sixty-one protein spots were differentially expressed between the IBS group and the Tongxieyaofang treatment group. Of these, 23 spots were upregulated in the Tongxieyaofang treatment group, while 38 spots were downregulated. Three specific proteins were successfully identified from the five protein spots with the most obvious changes. The two upregulated proteins were transgelin(TAGLN) and acetaldehyde dehydrogenase 2(Aldh2) and the downregulated protein was cytokeratin 8(CK8).CONCLUSION: Tongxieyaofang can dose-dependently ameliorate visceral hypersensitivity in rats and the mechanism of action may involve the upregulation of TAGLN and Aldh2 and the downregulation of CK8.Lin Yongjun Ding Ying Lü Bin Liu Nan 2020Journal of Traditional Chinese Medicine2020,40,2:4

16Synchronous Synthesis and Immobilization of Metal Phthalocyanine for Aerobic Oxidation of Styrene显示文摘In this study,the precursor 4-(4-carboxy-phenoxy)phthalonitrile(CPPN)was first bonded onto the silica gel surface modified with poly(glycidyl methacrylate)(PGMA)(PGMA/SiO2)to prepare CPPN-PGMA/SiO2,and metal phthalocyanine(MPc;M=Co,Fe,Cu,Mn)was supported on the PGMA/SiO2 surface to prepare MPc-PGMA/SiO2 by synchronous synthesis and immobilization with phthalonitrile and metal salt in the solution.The chemical composition and surface morphology were characterized by the Fourier transform infrared(FTIR)spectroscopy,UV-Vis spectroscopy,scanning electron microscopy(SEM),X-ray photoelectron spectroscopy(XPS),and thermogravimetry analysis(TGA).The catalytic performance of MPc-PGMA/SiO2 in epoxidation of styrene was also investigated with molecular oxygen acting as the oxidant.The results show that MPc-PGMA/SiO2 can efficiently and selectively catalyze molecular oxygen for oxidation of styrene to styrene oxide under mild conditions.However,the catalytic activity differs substantially depending on the central metal,and a highest catalytic activity is achieved by CoPc-PGMA/SiO2.The CoPc-PGMA/SiO2 amount and temperature can also affect the catalytic oxidation of styrene,and at normal atmospheric pressure,a maximum conversion rate of styrene(99%)and selectivity of styrene oxide(53%)are obtained using 0.1 g of CoPc-PGMA/SiO2(22.61μmol of CoPc)at 100℃ for 6 h.CoPc-PGMA/SiO2 also has excellent reusability,and the conversion rate of styrene is still over 90%after 5 cycles.Liu Yefeng LüYing Li Zeyu Shen Yue Wang Ruixin 2020China Petroleum Processing & Petrochemical Technology2020,22,4:1
17Nonreciprocal generation of Schrodinger cat state induced by topology显示文摘The Schrodinger cat state produced differently in two directions is anticipated to be a critical quantum resource in quantum information technologies.By exploring the interplay between quantum nonreciprocity and topology in a one-dimensional microcavity array,we obtain the Schrodinger cat state(a pure quantum state)in a chosen direction at the edge cavity,whereas a classical state in the other direction.This nonreciprocal generation of the cat state originates from the topologically protected chiralitymode excitation in the nontrivial phase,but in the trivial phase,the nonreciprocal generation of cat state vanishes.Thus,our proposal is switchable by tuning the parameters so that a topological phase transition occurs.Moreover,the obtained cat state has nonreciprocal high fidelity,nonclassicality,and quantum coherence,which are sufficient to be used in various one-way quantum technologies,e.g.,invisible quantum sensing,noise-tolerant quantum computing,and chiral quantum networks.Our work provides a general approach to control quantum nonreciprocities with the topological effect,which substantially broadens the fields of nonreciprocal photonics and topological physics.Zi-Hao Li Li-Li Zheng Ying Wu Xin-You Lü 2024Science China(Physics,Mechanics & Astronomy)2024,67,4:0
18Identification of Antarctic minke and killer whales with passive acoustic monitoring in Prydz Bay, Antarctica显示文摘Although four species of odontocete and four species of baleen whale have been recorded in Prydz Bay,their vocalizations have been rarely investigated.Underwater vocalizations were recorded during March 2017 in Prydz Bay,Antarctica.Bio-duck sounds,downsweeps,inverted“u”shape signals,whistles,pulsed sounds,and broadband clicks were recorded.Bio-duck sounds and downsweeps were associated with Antarctic minke whales(Balaenoptera bonaerensis)based on visual observations.Similarities between inverted“u”shape signals,biphonic calls,and clicks with vocalizations previously described for killer whales(Orcinus orca)lead us believe the presence of Antarctic killer whales.According to sound structures,signal characteristics,and recording location,Antarctic type C killer whales were the most probable candidates to produce these detected calls.These represent the fi rst detection of inverted“u”shape signals in Antarctic waters,and the fi rst report of Antarctic killer whale in Prydz Bay based on passive acoustic monitoring.The co-existence of Antarctic minke and killer whales may imply that minke whales can detect diff erences between the sounds of mammal-eating and fi sh-eating killer whales.Our descriptions of these underwater vocalizations contribute to the limited body of information regarding the distribution and acoustic behavior of cetaceans in Prydz Bay.Ying JIANG Lian-Gang LÜ Zongwei LIU Chunmei YANG Jingsong GUO 2022Journal of Oceanology and Limnology2022,40,2:0
19Cavity optomechanical chaos显示文摘Cavity optomechanics provides a powerful platform for observing many interesting classical and quantum nonlinear phenomena due to the radiation-pressure coupling between its optical and mechanical modes.In particular,the chaos induced by optomechanical nonlinearity has been of great concern because of its importance both in fundamental physics and potential applications ranging from secret information processing to optical communications.This review focuses on the chaotic dynamics in optomechanical systems.The basic theory of general nonlinear dynamics and the fundamental properties of chaos are introduced.Several nonlinear dynamical effects in optomechanical systems are demonstrated.Moreover,recent remarkable theoretical and experimental efforts in manipulating optomechanical chaotic motions are addressed.Future perspectives of chaos in hybrid systems are also discussed.Gui-Lei Zhu Chang-Sheng Hu Ying Wu Xin-You Lü 2023Fundamental Research2023,3,1:0
