    On-chip quantum NOON state sensing for temperature and humidity

    罗伟宏吴超杜昱星赵畅...
    15-21页
    查看更多>>摘要：A maximal photon number entangled state,namely NOON state,can be adopted for sensing with a quantum enhanced precision.In this work,we designed silicon quantum photonic chips containing two types of Mach-Zehnder interferometers wherein the two-photon NOON state,sensing element for temperature or humidity,is generated.Compared with classical light or single photon case,two-photon NOON state sensing shows a solid enhancement in the sensing resolution and precision.As the first demonstration of on-chip quantum photonic sensing,it reveals the advantages of photonic chips for high integration density,small-size,stability for multiple-parameter sensing serviceability.A higher sensing precision is expected to beat the standard quantum limit with a higher photon number NOON state.

    Vector magnetometry in zero bias magnetic field using nitrogen-vacancy ensembles

    李春兴石发展周经纬王鹏飞...
    22-31页
    查看更多>>摘要：The application of the vector magnetometry based on nitrogen-vacancy(NV)ensembles has been widely investigated in multiple areas.It has the superiority of high sensitivity and high stability in ambient conditions with microscale spatial resolution.However,a bias magnetic field is necessary to fully separate the resonance lines of optically detected magnetic resonance(ODMR)spectrum of NV ensembles.This brings disturbances in samples being detected and limits the range of application.Here,we demonstrate a method of vector magnetometry in zero bias magnetic field using NV ensembles.By utilizing the anisotropy property of fluorescence excited from NV centers,we analyzed the ODMR spectrum of NV ensembles under various polarized angles of excitation laser in zero bias magnetic field with a quantitative numerical model and reconstructed the magnetic field vector.The minimum magnetic field modulus that can be resolved accurately is down to～0.64 G theoretically depending on the ODMR spectral line width(1.8 MHz),and～2 G experimentally due to noises in fluorescence signals and errors in calibration.By using 13C purified and low nitrogen concentration diamond combined with improving calibration of unknown parameters,the ODMR spectral line width can be further decreased below 0.5 MHz,corresponding to～0.18 G minimum resolvable magnetic field modulus.

    Magnetoresistance hysteresis in the superconducting state of kagome CsV3Sb5

    乐天刘锦锦王秩伟林效...
    32-37页
    查看更多>>摘要：The hysteresis of magnetoresistance observed in superconductors is of great interest due to its potential connection with unconventional superconductivity.In this study,we perform electrical transport measurements on kagome supercon-ductor CsV3Sb5 nanoflakes and uncover unusual hysteretic behavior of magnetoresistance in the superconducting state.This hysteresis can be induced by applying either a large DC or AC current at temperatures(T)well below the super-conducting transition temperature(Tc).As T approaches Tc,similar weak hysteresis is also detected by applying a small current.Various scenarios are discussed,with particular focus on the effects of vortex pinning and the presence of time-reversal-symmtery-breaking superconducting domains.Our findings support the latter,hinting at chiral superconductivity in kagome superconductors.

    Surface-sensitive electronic structure of kagome superconductor CsV3Sb5

    赵志生姚江浩徐瑞王禹喆...
    38-44页
    查看更多>>摘要：We systematically study the electronic structure of a kagome superconductor CsV3Sb5 at different temperatures cov-ering both its charge density wave state and normal state with angle-resolved photoemission spectroscopy.We observe that the V-shaped band around(-Γ)shows three different behaviors,referred to as α/α',β and γ,mainly at different tempera-tures.Detailed investigations confirm that these bands are all from the same bulk Sb-pz origin,but they are quite sensitive to the sample surface conditions mainly modulated by temperature.Thus,the intriguing temperature dependent electronic behavior of the band near(-Γ)is affected by the sample surface condition,rather than intrinsic electronic behavior originating from the phase transition.Our result systematically reveals the confusing electronic structure behavior of the energy bands around(-Γ),facilitating further exploration of the novel properties in this material.

    Pairing correlation of the kagome-lattice Hubbard model with the nearest-neighbor interaction

    杨晨陈超马润宇梁颖...
    45-50页
    查看更多>>摘要：A recently discovered family of kagome lattice materials,AV3Sb5(A=K,Rb,Cs),has attracted great interest,espe-cially in the debate over their dominant superconducting pairing symmetry.To explore this issue,we study the supercon-ducting pairing behavior within the kagome-lattice Hubbard model through the constrained path Monte Carlo method.It is found that doping around the Dirac point generates a dominant next-nearest-neighbor-d pairing symmetry driven by on-site Coulomb interaction U.However,when considering the nearest-neighbor interaction V,it may induce nearest-neighbor-p pairing to become the preferred pairing symmetry.Our results provide useful information to identify the dominant super-conducting pairing symmetry in the AV3Sb5 family.

    Anomalous Hall effect and electronic correlation in a spin-reoriented kagome antiferromagnet LuFe6Sn6

    吕孟刘洋张伸刘俊艳...
    51-57页
    查看更多>>摘要：The kagome lattice system has been identified as a fertile ground for the emergence of a number of new quantum states,including superconductivity,quantum spin liquids,and topological electronic states.This has attracted significant interest within the field of condensed matter physics.Here,we present the observation of an anomalous Hall effect in an iron-based kagome antiferromagnet LuFe6Sn6,which implies a non-zero Berry curvature in this compound.By means of extensive magnetic measurements,a high Neel temperature,TN=552 K,and a spin reorientation behavior were identified and a simple temperature-field phase diagram was constructed.Furthermore,this compound was found to exhibit a large Sommerfeld coefficient of γ=87 mJ·mol-1·K-2,suggesting the presence of a strong electronic correlation effect.Our research indicates that LuFe6Sn6 is an intriguing compound that may exhibit magnetism,strong correlation,and topological states.

    Fully relativistic energies,transition properties,and lifetimes of lithium-like germanium

    李双周璟朱柳红梅秀菲...
    58-68页
    查看更多>>摘要：Employing two fully relativistic methods,the multi-reference configuration Dirac-Hartree-Fock(MCDHF)method and the relativistic many-body perturbation theory(RMBPT)method,we report energies and lifetime values for the lowest 35 energy levels of the(1s2)nl configurations(where the principal quantum number n=2-6 and the angular quantum num-ber l=0,...,n-1)of lithium-like germanium(Ge XXX),as well as complete data on the transition wavelengths,radiative rates,absorption oscillator strengths,and line strengths between the levels.Both the allowed(E1)and forbidden(magnetic dipole M1,magnetic quadrupole M2,and electric quadrupole E2)ones are reported.The results from the two methods are consistent with each other and align well with previous accurate experimental and theoretical findings.We assess the overall accuracies of present RMBPT results to be likely the most precise ones to date.The present fully relativistic results should be helpful for soft x-ray laser research,spectral line identification,plasma modeling and diagnosing.The datasets presented in this paper are openly available at https://doi.org/10.57760/sciencedb.j00113.00135.

    Charge self-consistent dynamical mean field theory calculations in combination with linear combination of numerical atomic orbitals framework based density functional theory

    瞿鑫许鹏刘志勇王金涛...
    69-77页
    查看更多>>摘要：We present a formalism of charge self-consistent dynamical mean field theory(DMFT)in combination with density functional theory(DFT)within the linear combination of numerical atomic orbitals(LCNAO)framework.We imple-mented the charge self-consistent DFT+DMFT formalism by interfacing a full-potential all-electron DFT code with three hybridization expansion-based continuous-time quantum Monte Carlo impurity solvers.The benchmarks on several 3d,4f and 5f strongly correlated electron systems validated our formalism and implementation.Furthermore,within the LCANO framework,our formalism is general and the code architecture is extensible,so it can work as a bridge merging different LCNAO DFT packages and impurity solvers to do charge self-consistent DFT+DMFT calculations.

    Impact of asymptomatic infected individuals on epidemic transmission dynamics in multiplex networks with partial coupling

    胡鑫陈嘉兴夏承遗
    89-97页
    查看更多>>摘要：The theory of network science has attracted great interest of many researchers in the realm of biomathematics and public health,and numerous valuable epidemic models have been developed.In previous studies,it is common to set up a one-to-one correspondence between the nodes of a multi-layer network,ignoring the more complex situations in reality.In the present work,we explore this situation by setting up a partially coupled model of a two-layer network and investigating the impact of asymptomatic infected individuals on epidemics.We propose a self-discovery mechanism for asymptomatic infected individuals,taking into account situations such as nucleic acid testing in the community and individuals performing self-antigen testing during the epidemic.Considering these factors together,through the microscopic Markov chain approach(MMCA)and extensive Monte Carlo(MC)numerical simulations,we find that the greater the coupling between the networks,the more information dissemination is facilitated.In order to control the epidemics,more asymptomatic infected individuals should be made aware of their infection.Massive adoption of nucleic acid testing and individual adoption of antigenic self-testing can help to contain epidemic outbreaks.Meanwhile,the epidemic threshold of the proposed model is derived,and then miscellaneous factors affecting the epidemic threshold are also discussed.Current results are conducive to devising the prevention and control policies of pandemics.
