Van der Waals materials, like hexagonal boron nitride (hBN) and other transition metal dichalcogenides (TMDs), present unique opportunities for controlling polaritonic modes due to their atomically thin structures and tunable optical properties. Specifically, hyperbolic polaritons in hBN enable extreme light confinement and canalization in the mid-infrared spectral range, while exciton-polaritons in TMDs exhibit strong nonlinear responses in the visible and near-infrared domains. Integrating van der Waals materials with metasurface—a tailored array of subwavelength scatterers—enables the creation of topologically protected polaritonic states, allowing unidirectional, scattering-resistant propagation. This review provides a brief review of the rapidly advancing field of topological polaritonics in van der Waals metasurfaces, covering not only topological polaritonic insulators but also hyperbolic polaritons exhibiting topological transition in their dispersion contour.</div></div>","PeriodicalId":37875,"journal":{"name":"Reviews in Physics","volume":"13 ","pages":"Article 100115"},"PeriodicalIF":0.0,"publicationDate":"2025-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143738231","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This extension focuses on modelling the physical, chemical, and biological stages of ionising radiation for radiobiological applications at cellular and DNA level interactions. To date, review papers on GEANT4-DNA focus solely on evaluating a selection of the latest developments with a greater focus on mechanistic developments rather than progress in biologically specific geometries. In this work, an overview of biological analysis and biological geometries that have been developed are discussed, highlighting the latest developments and future possible development avenues for GEANT4-DNA for this application. An overview of the biological organisation levels, namely DNA, cellular, and population levels, and how GEANT4-DNA models the physical, chemical, and biological processes are also described. This review emphasises the need for persistent development of specific biological geometry accompanied by personalised DNA damage analysis parameters dependent on the biological processes considered within a specific model. It also provides an in-depth understanding of the advances at all the biological organisation levels (DNA, cellular, and population) and the use of co-operative platforms developed to model alongside GEANT4 to provide further detailed geometries and or biological damage analysis. The developments presented have been analytically discussed along with their key findings and prospects for GEANT4-DNA. Finally, a perspective on future necessary developments is portrayed since many of the advancements in the biological analysis and biological geometries discussed have not been exploited to their full potential. The development of GEANT4-DNA, using the advances discussed in this review, provides a favourable method for the evaluation of biological damage comparable to radiobiological studies.</div></div>","PeriodicalId":37875,"journal":{"name":"Reviews in Physics","volume":"13 ","pages":"Article 100110"},"PeriodicalIF":0.0,"publicationDate":"2025-02-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143463452","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

An external light is injected into each node's laser in one chain and a center's laser to enable the closed optical network to be developed into an open optical network. Our study demonstrates that chaos control of each node laser of the network can be achieved via external light injection, and network parallel synchronization can be obtained in two chains. We find the controlled quasi-periodic synchronization regions. When dynamic chaos control of the network is achieved by shifting the external light injection, the network obtains quasi-periodic parallel synchronization in two chains. We provide a bifurcation diagram of the closed network, a bifurcation diagram of the open network, and a bifurcation diagram varying with the external light injection, displaying routes to chaos after passing double-periodic bifurcation through four-period or quasi-period. We find that there are clear, different routes to chaos operated in the closed network and the open network and that external light injection can guide a route away from chaos, while chaos control is achieved in the open network. The results have important reference value for the study of the control and synchronization of optical networks, laser technology, complex systems, and chaos.</div></div>","PeriodicalId":37875,"journal":{"name":"Reviews in Physics","volume":"13 ","pages":"Article 100107"},"PeriodicalIF":0.0,"publicationDate":"2025-02-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143350845","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Key features of the Floquet-Magnus expansion are its ability to account for the calculations developed in a finite-dimensional Hilbert space instead of an infinite-dimensional space within the Floquet theory as well as its use of its distinguishable function, <span><math><mrow><msub><mstyle><mi>Λ</mi></mstyle><mi>n</mi></msub><mrow><mo>(</mo><mi>t</mi><mo>)</mo></mrow><mo>,</mo><mspace></mspace><mi>n</mi><mo>=</mo><mn>1</mn><mo>,</mo><mspace></mspace><mn>2</mn><mo>,</mo><mspace></mspace><mn>3</mn><mo>,</mo><mspace></mspace><mi>…</mi></mrow></math></span>, not available in other concurrent theories such as average Hamiltonian theory, Floquet theory, and Fer expansion. The distinguishable function facilitates the evaluation of the spin behavior in between the stroboscopic observation points. This paper provides an in-depth analysis of both the FME and FE methods and integrates them with the Triple Oscillating Field Technique (TOFU) in solid-state NMR. This is a significant and novel contribution as it presents a unified framework for explaining spin dynamics. The use of both FME and FE provides new theoretical insights and extends the applicability of these methods beyond traditional approaches. The application to the TOFU technique, which circumvents the dipolar truncation problem, indicates substantial practical implications for distance measurement in solid-state NMR, a critical aspect of molecular structure determination. We take advantage of the interaction frequencies and the time modulation arising from the TOFU pulse sequence, which allows selective recoupling of specific terms in the Hamiltonian that fulfill determined specific conditions. The work presented unifies and generalizes the results of the FME and FE and delivers illustrations of novel insights that boost previous applications that are based on the classical information. We believe that the revisited approaches in this work and the derived expressions can serve as useful information and numerical tools for time evolution in spin dynamics, time-resolved spectroscopy, quantum control, and quantum dynamics[<span><span>81</span></span>,<span><span>82</span></span>].</div></div>","PeriodicalId":37875,"journal":{"name":"Reviews in Physics","volume":"13 ","pages":"Article 100109"},"PeriodicalIF":0.0,"publicationDate":"2025-02-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143350846","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
