In recent era, there has been a boosting inclination towards the investigation of Heusler materials, owing to their extensive applications in thermoelectronics and optospintronics. The structural, elastic, electronic, magnetic and thermoelectric properties of RuCrM (M = Si, Ge, Sn, Sb) half-Heuslers are systematically studied by using the DFT and DFT + U methods. The calculated results of lattice constant and bulk modulus are in good agreement with the existing theoretical data for similar RuCrM systems. The magnetic and electronic properties reveal that RuCrM are FM metallic materials. In addition, the two types of doping by electrons and holes at various temperatures are investigated for RuCrM, and their optimum structural type is estimated. This study concludes that the U energy has the potential to enhance the properties of RuCrM. Such remarkable properties provide strong evidence that the stable compounds of RuCrM are suitable and promising materials for future thermoelectronics and optospintronics applications.

The role of laser field in the electron transport through serially coupled double-quantum dots 激光场在串联耦合双量子点电子传输中的作用
IF 1.6 4区 物理与天体物理 Q3 PHYSICS, CONDENSED MATTER Pub Date : 2024-12-17 DOI: 10.1140/epjb/s10051-024-00833-x

In this study, a mathematical model is developed to study the transport properties of a system consisting of serially coupled double-quantum dots embedded between two nonmagnetic leads in the presence of a laser field effect on double-quantum dots. To examine the device properties and develop a spin-dependent analytical formula for the occupancy numbers, related quantum dot energy levels and the molecular virtual levels, the treatment in this research is based on the time-independent Anderson–Newns model. These formulas are solved self-consistently to compute the tunneling current which is utilized to calculate the differential conductance “Our calculations focus on the strong regime”. All the parameters that included in our calculations can be tuned experimentally. It is found that the electron transport through the system is enhanced as the frequency of the laser field increases, and the energy window is getting wider too. These results are very important to be applied to nano-devices, since the laser can be used as a tool to assist the transport of electrons through the system.

Complex network analysis of transmission networks preparing for the energy transition: application to the current French power grid 为能源转型做准备的输电网复杂网络分析:在当前法国电网中的应用
IF 1.6 4区 物理与天体物理 Q3 PHYSICS, CONDENSED MATTER Pub Date : 2024-12-17 DOI: 10.1140/epjb/s10051-024-00837-7

 The worldwide process of replacing fossil fuels with low-carbon energy sources is underway. Existing energy networks are expected to be deeply modified in nature and structure during this transition. This work uses graph-theoretical statistical physics tools to analyze topology and structural changes of power grids, with the French grid as a case study. We discuss the small-world model to define an optimality criterion, the construction of a graph model for the French high-voltage transmission grid, and the development of a growth model to study the dynamics of such networks. The main result of our project suggests that the high efficiency level in the current French network is due to a high-voltage mesh interconnecting thermal power plants. Since implementing low-power-density renewable energy sources would imply non-trivial adjustments to maintain features, such as efficiency and robustness, these considerations must be added to economic and energetic assessments of transition scenarios.

世界范围内用低碳能源替代化石燃料的进程正在进行。在这一转型过程中,现有能源网络的性质和结构预计将发生深刻变化。本研究以法国电网为例,使用图理论统计物理工具分析电网的拓扑结构变化。我们讨论了小世界模型来定义最优性准则,构建了法国高压输电网的图模型,并建立了增长模型来研究高压输电网的动力学。我们项目的主要结果表明,目前法国电网的高效率水平是由于高压网格互连火电厂。由于实施低功率密度的可再生能源将意味着为维持诸如效率和健壮性等特征而进行重大调整,因此必须将这些考虑因素加入到对过渡情景的经济和能源评估中。

On-chip high kinetic inductance LC filters modeled with a distributed circuit model 采用分布式电路模型建模的片上高动能电感 LC 滤波器
IF 1.6 4区 物理与天体物理 Q3 PHYSICS, CONDENSED MATTER Pub Date : 2024-12-16 DOI: 10.1140/epjb/s10051-024-00836-8

In a hybrid system of quantum dots coupled with microwave resonators, to address the large footprints challenge posed by conventional-material on-chip low-pass filters which are inserted to suppress resonator photon leakage, the utilization of filters with high kinetic inductance (HKI) materials has been demonstrated. However, the HKI film induces the distributed parasitic kinetic inductance to the capacitor structure, making the lumped circuit model which generally used to simulate the filter face failure, and hindering the superconducting filter performance. In our work, we fabricate a compact HKI planar filter and observe that the measured response curve exhibits a large deviation from the simulation result of the lumped circuit model. We propose a distributed circuit model to more accurately simulate transmission characteristics of the HKI filter. By analyzing the effect of parasitic inductance induced by the distributed kinetic inductance film, we explain the abnormal roll-off phenomenon observed in the transmission response curve of the HKI filter. Combining the Fano effect, the simulation result with the distributed model exhibits better correspondence with the experimental results than that of the lumped model. The developed circuit model will contribute to analyzing the adverse effects and optimizing the device design of the HKI film.

在量子点与微波谐振器耦合的混合系统中,为解决插入传统材料片上低通滤波器以抑制谐振器光子泄漏所带来的大尺寸挑战,利用高动能电感(HKI)材料的滤波器已得到证实。然而,高动能电感薄膜会在电容器结构中产生分布式寄生动能电感,使得通常用于模拟滤波器的块状电路模型面临失效,并阻碍了超导滤波器性能的发挥。在我们的工作中,我们制作了一个紧凑的 HKI 平面滤波器,并观察到测量的响应曲线与块状电路模型的模拟结果有很大偏差。我们提出了一种分布式电路模型,以更精确地模拟 HKI 滤波器的传输特性。通过分析分布式动电感薄膜引起的寄生电感的影响,我们解释了在 HKI 滤波器传输响应曲线上观察到的异常滚降现象。结合法诺效应,分布式模型的仿真结果与实验结果的对应关系优于块状模型。所开发的电路模型将有助于分析 HKI 薄膜的不利影响和优化器件设计。

Cerium dioxide (CeO2) or Ceria nanorods were produced in the current work, using the chemical precipitation approach. X-ray diffraction (XRD), Fourier transform infrared (FTIR) spectroscopy, X-ray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM), UV–visible, photoluminescence (PL), and electrochemical impedance spectroscopy (EIS), thermogravimetric and differential thermal analyses (TG/DTA) were used to assess the material characteristics of the produced samples. The XRD results reveal that the CeO2 nanorods crystallized into the cubic fluorite crystal system. Micro-strain dislocation density, gain size and cell volume of the samples were assessed. XPS examination was performed to verify the chemical states of the constituent elements in CeO2 nanorods. FTIR spectral analysis was used to investigate chemical bonds and molecular vibrations in CeO2 nanorods. SEM analysis was used to observe the grain structure of CeO2 nanorods. UV–visible spectroscopy determined the CeO2 optical absorption characteristics, bandgap, and Urbach energy. PL study and CIE-chromaticity mapping were used to investigate the light-emitting characteristics of the CeO2 nanorods. The EIS method was applied to examine the impedance nature of CeO2 nanorods. TGA/DTA investigations were performed to find the thermal characteristics of CeO2 nanorods. The study findings indicate the usefulness of CeO2 nanorods as electrodes and optoelectronic materials.

In this paper, we examine the performance characteristics at maximum cooling power for a parallelly connected two quantum dots refrigerator within the framework of ballistic electron transport between two reservoirs. The coefficient of performance (COP) at the maximum cooling power, which depends on the Carnot bound, was analyzed for a refrigerator of the quantum dot(QD) system and successfully compared with the Curzon–Ahlborn coefficient of performance. Besides, the coefficient of performance at the maximum cooling power of the model was demonstrated through numerical analysis. Our results indicate that the coefficient of performance at maximum cooling power differs from the Curzon–Ahlborn coefficient of performance in the limit of a small Carnot coefficient of performance. It is constrained by an upper bound of (varepsilon _C) and a lower bound of (varepsilon _{CA}).

This paper explores the problem of synchronous control of discrete complex network dynamics models. In view of the challenges such as the difficulty of modeling complex networks, the complexity of network structure and the difficulty of controller design, this paper proposes an improved model-free adaptive pinning control method. First, a method of entropy of the betweenness centrality and node strength is proposed to select the key nodes, construct the augmentation and generalization error system, and design the control strategy based on the node input and output data. Second, the synchronous stability is analyzed theoretically and the controller parameters are optimized by firefly optimization algorithm in order to overcome the parameter tuning difficulties. Finally, the effectiveness of the proposed pinning node selection strategy in this paper is verified by simulation, and it is verified by simulation experiments of BA scale-free network and ER stochastic network that the pinning control method in this paper only needs to control a few key nodes in the network to realize the synchronous state of the whole network. The method of this paper provides a new idea for synchronous control of complex networks.

研究离散复杂网络动力学模型的同步控制问题。针对复杂网络建模困难、网络结构复杂、控制器设计困难等问题,提出了一种改进的无模型自适应固定控制方法。首先,提出了基于节点间中心性和节点强度熵的关键节点选择方法,构建了误差增强泛化系统,并设计了基于节点输入输出数据的控制策略;其次,对系统的同步稳定性进行了理论分析,并采用萤火虫优化算法对控制器参数进行了优化,克服了参数整定的困难;最后,通过仿真验证了本文提出的钉住节点选择策略的有效性,并通过BA无标度网络和ER随机网络的仿真实验验证了本文所提出的钉住控制方法只需控制网络中的几个关键节点即可实现全网的同步状态。该方法为复杂网络的同步控制提供了一种新的思路。

This study introduces an extension of the classical Susceptible-Infectious-Recovered (SIR) model by incorporating individual self-protection awareness to more accurately reflect its impact on epidemic spread. We derive outbreak thresholds for both homogeneous and heterogeneous networks and validate the model through theoretical analysis. Key findings from numerical simulations on Erdős-Rényi (ER) and Barabási-Albert (BA) networks show that self-protective behaviors significantly reduce the epidemic spread. Notably, while heterogeneous networks demonstrate a more pronounced reduction in the peak of infected individuals, they still exhibit a larger final infection scale and a lower outbreak threshold. These results highlight the dual impact of network structure and self-protection awareness on epidemic dynamics, offering new insights for infectious disease control strategies.

本研究引入了经典的易感-感染-恢复(SIR)模型的扩展,通过纳入个体自我保护意识来更准确地反映其对流行病传播的影响。我们推导了同质和异质网络的爆发阈值,并通过理论分析验证了模型。在Erdős-Rényi (ER)和Barabási-Albert (BA)网络上的数值模拟结果表明,自我保护行为显著减少了疫情的传播。值得注意的是,尽管异质网络显示出受感染个体峰值的更明显减少,但它们仍然表现出更大的最终感染规模和更低的爆发阈值。这些结果突出了网络结构和自我保护意识对流行病动态的双重影响,为传染病控制策略提供了新的见解。

New experiment on non-stationary neutron diffraction by a traveling surface acoustic wave 行表面声波对非定常中子衍射的新实验
IF 1.6 4区 物理与天体物理 Q3 PHYSICS, CONDENSED MATTER Pub Date : 2024-12-10 DOI: 10.1140/epjb/s10051-024-00829-7

The results of a new experiment on neutron diffraction by surface acoustic waves are presented. The measurements were carried out at a fixed incident angle in the time-of-flight mode, which made it possible to study the diffraction pattern in a wide range of neutron wavelengths at surface acoustic wave frequencies from 35 to 117 MHz. In a number of cases, diffracted waves of not only the first but also the second order were observed. The measurement results of both the angular distribution of diffracted waves and their amplitudes are in satisfactory agreement with the calculations. A new estimation has been obtained for the range of applicability of the dispersion law of neutron waves in matter moving with large acceleration.

本文介绍了表面声波对中子衍射的新实验结果。测量在飞行时间模式下以固定入射角进行,这使得在表面声波频率从35到117 MHz的宽范围内研究中子波长的衍射图成为可能。在许多情况下,不仅观察到一级衍射波,而且观察到二级衍射波。衍射波的角分布和振幅的测量结果与计算结果吻合得很好。对中子色散定律在大加速度物质运动中的适用范围作了新的估计。
