The qubit cavity system represents an attractive structure for quantum optics, with possibilities for applications in quantum detecting, quantum computation, and quantum communication. In addition, the investigation of the cavity-atom system under temperature is a fundamental concept in quantum optics and quantum information science. Here we continue in this quantum way, investigating different qubit(s)-cavity systems (where we increase the numbers of the qubit inside the optical cavity from one to four). Using the Dicke model, we calculate the probability of occupation of the ground state of the cavity <span><math><mrow><mo>〈</mo><msup><mrow><mover><mrow><mi>a</mi></mrow><mrow><mo>ˆ</mo></mrow></mover></mrow><mrow><mi>†</mi></mrow></msup><mover><mrow><mi>a</mi></mrow><mrow><mo>ˆ</mo></mrow></mover><mo>〉</mo></mrow></math></span> and the expectation values <span><math><mrow><mo>〈</mo><msub><mrow><mi>J</mi></mrow><mrow><mi>z</mi></mrow></msub><mo>〉</mo></mrow></math></span> for each system.

This leads to reaching the ultra-strong coupling regime, which depends on the number of qubits.

Furthermore, since understanding these kinds of systems is very important in order to improve the quantum network system, we study the entropy <span><math><mi>S</mi></math></span> of the subsystems (such as <span><math><mi>S</mi></math></span> of qubit) in each system. Also, we move beyond by studying the effect of the temperature on the Fock-state distribution occupation probability and entropy of the subsystems. Our results present another step to understanding the qubit(s)-cavity interaction to improve the performance of future quantum networks based on this system. Where the interplay between temperature, coupling strengths, and the Fock-state occupation probabilities contributes significantly to the understanding of quantum decoherence and the thermodynamic properties of quantum systems. Our research on cavity qubit systems is crucial to the development and practical use of quantum networks, which will open the door to distributed quantum computing and other quantum technologies.</div></div>","PeriodicalId":21042,"journal":{"name":"Results in Physics","volume":"72 ","pages":"Article 108214"},"PeriodicalIF":4.4,"publicationDate":"2025-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143714759","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}

In the insulating phase, the structure achieves remarkable AT, with transmission coefficients reaching 0.95, supporting selective polarization conversion over an extensive frequency range (0.2–1.0 THz). Upon transitioning VO<sub>2</sub> to a metallic state, the AT effect diminishes significantly, allowing the device to exhibit LD by selectively absorbing linearly polarized THz waves. This reconfigurable behavior underscores the potential of phase-change materials to advance the field of active THz metamaterials, with applications in polarization manipulation, selective THz absorption, and tunable optoelectronic devices.</div></div>","PeriodicalId":21042,"journal":{"name":"Results in Physics","volume":"72 ","pages":"Article 108229"},"PeriodicalIF":4.4,"publicationDate":"2025-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143725503","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}

It considers the integrated effects of Coriolis force, velocity slip, thermal radiation, Hall and ion slip, viscous dissipation, non-uniform heat source/sink, and chemical reactions on the flow. Main features of the analysis are the formulation of the Navier stokes equations, energy and concentration equations using the Cattaneo–Christov heat and mass flux models, rather than the classical Fourier’s law and Fick’s law, which is used to account for time relaxation effects. The governing nonlinear, coupled partial differential equations are converted into an ordinary differential system using similarity variables and then solved numerically using the finite element method. Sensitivity analysis using the response surface methodology exhibits the conditions for optimized heat transfer. The noteworthy findings are presented through graphical analyses of fluid flow parameters. The study reveals that the magnetic field slows fluid flow, while velocity increases with Hall and ion slip effects, mixed convection, concentration buoyancy parameters, and the Darcy number. Moreover, temperature increases with Brownian diffusion, the Eckert number, and radiation but decreases with a higher Prandtl number and thermal relaxation time. Moreover, as the Hall and ion slip parameters increase, the velocity profile also intensifies. The analysis reveals that the Prandtl number (Pr) is the dominant parameter, consistently exhibiting the highest Partial rank correlation coefficient(PRCC) value of 0.8650, emphasizing its crucial role in influencing the system’s behavior. Reliability is ensured through grid convergence analysis, and the numerical results were rigorously validated through detailed comparisons with previous studies and benchmark solutions. These findings are particularly relevant for energy systems, materials processing, and other industrial processes involving nanofluids in porous media, where precise control of thermal and fluid flow properties is crucial. Additionally, extending the study to other non-Newtonian fluids will broaden the applicability to a wider range of industrial applications.</div></div>","PeriodicalId":21042,"journal":{"name":"Results in Physics","volume":"72 ","pages":"Article 108201"},"PeriodicalIF":4.4,"publicationDate":"2025-03-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143683218","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}
