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.</p><h3>Graphical Abstract</h3><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":787,"journal":{"name":"The European Physical Journal B","volume":"97 12","pages":""},"PeriodicalIF":1.6,"publicationDate":"2024-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142844797","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.</p><h3>Graphical abstract</h3>\u0000<div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":787,"journal":{"name":"The European Physical Journal B","volume":"97 12","pages":""},"PeriodicalIF":1.6,"publicationDate":"2024-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142844922","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.

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.</p>","PeriodicalId":787,"journal":{"name":"The European Physical Journal B","volume":"97 12","pages":""},"PeriodicalIF":1.6,"publicationDate":"2024-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142826165","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.
