Formation of random ferromagnetic clusters in the paramagnetic state for <em>x</em> = 0.1 is noticed through Griffith’s phase signatures in inverse susceptibility. Rhodes–Wohlfarth analysis confirms the itinerant magnetic nature. These alloys exhibit metallic character with Fermi liquid behavior at low temperatures. Relatively smaller negative magneto-resistance indicates the suppression of itinerant spin fluctuations and incoherent scattering of conduction electrons. Second order magnetic phase transition is inferred from a well-scaled normalized magneto-resistance independent of magnetic field strength.

Here, we propose an integrated polarization spectroscopy detector operating in the mid-infrared range based on a tunable graphene metasurface. Within the graphene metasurface, plasmonic resonances of graphene are excited by a gold nano-grating, allowing simultaneous modulation of spectral and polarization transmission characteristics for infrared light by tuning the Fermi energy of graphene. With the help of neural network based recovery algorithms, this system achieves pixel-level spectral detection (with a resolution below 200 nm), multi-color polarization Stokes vector analysis (with a monochromatic angular error of less than 0.1 rad), and concurrent polarization and spectroscopy detection.

A sensor, for measuring the complex refractive index of turbid media in real-time, with divergent light source is designed. The captured images show that the light distribution reflected from the transparent medium has a sharp boundary, but for turbid media, the reflected light intensity attenuates during the transition from total to non-total internal reflection regions.

Study on the properties of different planes is of great significance to enhance the comprehensive utilization of molybdenite, especially in flotation. In order to explore the properties of different planes, the two main planes of molybdenite (basal plane and edge plane) are respectively taken as the research object in this paper, and the properties of planes are expressed using DFT through the adsorption behaviors of a new reagent named DTC-CTS and water molecules. The results show that edge plane has higher activity than basal plane. This is because there are exposed molybdenum atoms on the edge plane, and the sulfur atoms in DTC-CTS and oxygen atoms in water molecules are easy to react with the exposed molybdenum atoms. While the activity of basal plane is low because of the hinderance effect of sulfur atoms in the skin layer. The different adsorption behaviors of water molecules on molybdenite planes verified the hydrophobicity of different planes. In addition, the results also show that the water can affect the DTC-CTS adsorption on edge plane. Water can enhance interaction between single-bond sulfur atom and molybdenum atom, and weaken the interaction between double-bond sulfur atom and molybdenum atom on edge plane.</div></div>","PeriodicalId":21042,"journal":{"name":"Results in Physics","volume":"65 ","pages":"Article 107996"},"PeriodicalIF":4.4,"publicationDate":"2024-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142358819","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study of the local and global superfluid fraction allows the identification of supersolid, super quasicrystal, Bose glass and insulating phases. The Bose glass phase emerges as a quasicrystal phase in which the global superfluidity is essentially zero, while the local superfluidity remains finite in certain ring structures of the quasicrystalline pattern. Furthermore, we perform continuous space Path Integral Monte Carlo simulations for a case in which the interaction between particles stabilizes a quasicrystal phase.

A deeper comprehension of the dynamics between prey and predator can be achieved through the examination of indirect consequences. This work examines the dynamic behavior of a modified Holling-Tanner model. The interactions between the species are characterized by a functional response of the Beddington–DeAngelis type. Factors such as prey refuge, fear factor, disturbance intensity, and cross diffusion have been taken into account. The boundedness, feasibility of equilibrium points, their stability and restrictions for Hopf bifurcation of non-spatial model system are derived. The study explores the combined effects of prey refuge presence and fear factors on population dynamics. Furthermore, the investigation focuses on the stability of spatial self-diffusion and cross-diffusion model systems, as well as the specific conditions that lead to Turing instability. Ultimately, it has been shown that in the context of self-diffusion, a moderate level of fear promotes the survival of prey, whereas an excessive level of dread hinders the survival of prey. Concurrently, the mean density of prey exhibited a gradual decline as the refuge parameters increased. The spatial patterns of the population have also been investigated. As the mutual interference between prey populations intensifies, the spatial distribution of the prey population transitions from a clustered pattern to a combination of striped and clustered patterns, ultimately settling into a striped pattern. With the gradual growth of the half saturation constant, the prey population reached a state of uniform distribution. In the scenario of cross diffusion, when the prey is heavily impacted by the pursuit of predators, the fear effect, when appropriately used, did not have a significant impact on the survival of the prey. This work adds to the existing body of knowledge by revealing novel insights into the influence of indirect factors on the behavior of predator and prey populations.</div></div>","PeriodicalId":21042,"journal":{"name":"Results in Physics","volume":"65 ","pages":"Article 107995"},"PeriodicalIF":4.4,"publicationDate":"2024-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142358733","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
