    Bessel vortices in spin-1 Bose-Einstein condensates with Zeeman splitting and spin-orbit coupling

    罗焕波张鑫锋李润华黎永耀...
    180-187页
    查看更多>>摘要：We investigate the ground states of spin-orbit coupled spin-1 Bose-Einstein condensates in the presence of Zeeman splitting.By introducing the generalized momentum operator,the linear version of the system is solved exactly,yielding a set of Bessel vortices.Additionally,based on linear solution and using variational approximation,the solutions for the full nonlinear system and their ground state phase diagrams are derived,including the vortex states with quantum numbers m=0,1,as well as mixed states.In this work,mixed states in spin-1 spin-orbit coupling(SOC)BEC are interpreted for the first time as weighted superpositions of three vortex states.Furthermore,the results also indicate that under strong Zeeman splitting,the system cannot form localized states.The variational solutions align well with numerical simulations,showing stable evolution and meeting the criteria for long-term observation in experiments.

    Memristors-coupled neuron models with multiple firing patterns and homogeneous and heterogeneous multistability

    王暄Santo Banerjee曹颖鸿牟俊...
    199-213页
    查看更多>>摘要：Memristors are extensively used to estimate the external electromagnetic stimulation and synapses for neurons.In this paper,two distinct scenarios,i.e.,an ideal memristor serves as external electromagnetic stimulation and a locally active memristor serves as a synapse,are formulated to investigate the impact of a memristor on a two-dimensional Hindmarsh-Rose neuron model.Numerical simulations show that the neuronal models in different scenarios have multiple burst firing patterns.The introduction of the memristor makes the neuronal model exhibit complex dynamical behaviors.Finally,the simulation circuit and DSP hardware implementation results validate the physical mechanism,as well as the reliability of the biological neuron model.

    Effective regulation of the interaction process among three optical solitons

    伊厚会李晓凤张俊玲张鑫...
    214-222页
    查看更多>>摘要：The interaction between three optical solitons is a complex and valuable research direction,which is of practical application for promoting the development of optical communication and all-optical information processing technology.In this paper,we start from the study of the variable-coefficient coupled higher-order nonlinear Schrödinger equation(VCHNLSE),and obtain an analytical three-soliton solution of this equation.Based on the obtained solution,the interaction of the three optical solitons is explored when they are incident from different initial velocities and phases.When the higher-order dispersion and nonlinear functions are sinusoidal,hyperbolic secant,and hyperbolic tangent functions,the transmission properties of three optical solitons before and after interactions are discussed.Besides,this paper achieves effective regulation of amplitude and velocity of optical solitons as well as of the local state of interaction process,and interaction-free transmission of the three optical solitons is obtained with a small spacing.The relevant conclusions of the paper are of great significance in promoting the development of high-speed and large-capacity optical communication,optical signal processing,and optical computing.

    Optimization performance of quantum endoreversible Otto machines with dual-squeezed reservoirs

    223-230页
    查看更多>>摘要：We consider a quantum endoreversible Otto engine cycle and its inverse operation-Otto refrigeration cycle,employing two-level systems as the working substance and operating in dual-squeezed reservoirs.We demonstrate that the efficiency of heat engines at maximum work output and the coefficient of performance for refrigerators at the maximum x criterion will degenerate to η-=ηC/(2-ηC)and ε-=(√9+8εC-3)/2 when symmetric squeezing is satisfied,respectively.We also investigated the influences of squeezing degree on the performance optimization of quantum Otto heat engines at the maximum work output and refrigerators at the maximum x criterion.These analytical results show that the efficiency of heat engines at maximum work output and the coefficient of performance for refrigerators at the maximum x criterion can be improved,reduced or even inhibited in asymmetric squeezing.Furthermore,we also find that the efficiency of quantum Otto heat engines at maximum work output is lower than that obtained from the Otto heat engines based on a single harmonic oscillator system.However,the coefficient of performance of the corresponding refrigerator is higher.

    Thermodynamics of charged AdS black hole surrounded by quintessence in restricted phase space

    简思雨龙思颖陈菊华王永久...
    231-239页
    查看更多>>摘要：We study thermodynamics of charged AdS black hole surrounded by quintessence in a new formalism which is called the restricted phase space thermodynamics.This context is based on Visser's holographic thermodynamics with a fixed anti-de Sitter radius and a variable Newton constant.The conjugate variables,central charge C and the chemical potential μ,are introduced as a new pair of thermodynamic variables.We find that the iso-e-charge T-S curve becomes non-monotonic when Q＜Qc.Correspondingly,the F-T curve exhibits a swallow tail structure.This behavior is considered as a van der Waals-like phase transition.As the value of b related to the energy density of Kiselev's fluid becomes larger,the critical temperature Tc will decrease.Thus,the van der Waals-like phase transition will occur at lower temperature.There is always a non-quilibrium transition from a small unstable black hole to a large stable black hole state in the isocoltage T-S process.There exist a maximum and a Hawking-Page phase transition points in the μ-C plane.As the value of b related to Kiselev's fluid becomes larger,the Hawking-Page phase transition will occur at lower temperature in the isovoltage μ-T process.For other values of the state parameter ω,there also exists van der Waals-like phase transition.

    Geometric properties of the first singlet S-wave excited state of two-electron atoms near the critical nuclear charge

    陈彤杨三江周挽平梅雪松...
    240-247页
    查看更多>>摘要：The geometric structure parameters and radial density distribution of 1s2s 1S excited state of the two-electron atomic system near the critical nuclear charge Zc were calculated in detail under tripled Hylleraas basis set.Contrary to the localized behavior observed in the ground and the doubly excited 2p2 3pe states,for this state our results identify that while the behavior of the inner electron increasingly resembles that of a hydrogen-like atomic system,the outer electron in the excited state exhibits diffused hydrogen-like character and becomes perpendicular to the inner electron as nuclear charge Z approaches Zc.This study provides insights into the electronic structure and stability of the two-electron system in the vicinity of the critical nuclear charge.

    Photoelectron momentum distributions of triatomic CO2 molecules by circularly polarized attosecond pulses

    张思琪张军郝欣宇郭静...
    248-254页
    查看更多>>摘要：Molecular-frame photoelectron momentum distributions(MF-PMDs)have been studied for imaging molecular struc-tures.We investigate the MF-PMDs of C02 molecules exposed to circularly polarized(CP)attosecond laser pulses by solving the time-dependent Schrödinger equations based on the single-active-electron approximation frames.Results show that high-frequency photons lead to photoelectron diffraction patterns,indicating molecular orbitals.These diffraction patterns can be illustrated by the ultrafast photoionization models.However,for the driving pulses with 30 nm,a devia-tion between MF-PMDs and theoretically predicted results of the ultrafast photoionization models is produced because the Coulomb effect strongly influences the molecular photoionization.Meanwhile,the MF-PMDs rotate in the same direction as the helicity of driving laser pulses.Our results also demonstrate that the MF-PMDs in a CP laser pulse are the super-position of those in the parallel and perpendicular linearly polarized cases.The simulations efficiently visualize molecular orbital geometries and structures by ultrafast photoelectron imaging.Furthermore,we determine the contribution of HOMO and HOMO-1 orbitals to ionization by varying the relative phase and the ratio of these two orbitals.

    Imaging through scattering layers using a near-infrared low-spatial-coherence fiber random laser

    史安达王泽宇段辰锡王昭...
    255-262页
    查看更多>>摘要：Optical memory effect-based speckle-correlated technology has been developed for reconstructing hidden objects from disordered speckle patterns,achieving imaging through scattering layers.However,the lighting efficiency and field of view of existing speckle-correlated imaging systems are limited.Here,a near-infrared low spatial coherence fiber random laser illumination method is proposed to address the above limitations.Through the utilization of random Rayleigh scattering within dispersion-shifted fibers to provide feedback,coupled with stimulated Raman scattering for amplification,a near-infrared fiber random laser exhibiting a high spectral density and extremely low spatial coherence is generated.Based on the designed fiber random laser,speckle-correlated imaging through scattering layers is achieved,with high lighting efficiency and a large imaging field of view.This work improves the performance of speckle-correlated imaging and enriches the research on imaging through scattering medium.

    Reconstruction algorithm for cross-waveband optical computing imaging

    谢锦涛别书航李明飞余远金...
    263-270页
    查看更多>>摘要：In a single-pixel fast imaging setup,the data collected by the single-pixel detector needs to be processed by a computer,but the speed of the latter will affect the image reconstruction time.Here we propose two kinds of setups which are able to transform non-visible into visible light imaging,wherein their computing process is replaced by a camera integration mode.The image captured by the camera has a low contrast,so here we present an algorithm that can realize a high quality image in near-infrared to visible cross-waveband imaging.The scheme is verified both by simulation and in actual experiments.The setups demonstrate the great potential for single-pixel imaging and high-speed cross-waveband imaging for future practical applications.
