This review summarizes recent advances in microstructured LC devices, covering their fundamental properties, key degrees of freedom, and primary strategies for tunable optical field control. It focuses on three core research directions: linear optical control in LC-based waveguides, nonlinear manipulation via spatial optical solitons, and lasing in LC microdroplets. A central theme is the unique ability of LC systems to transcend the geometric and functional constraints of conventional solid-state photonics through dynamic, reconfigurable architectures. Looking forward, the field is poised for breakthroughs in multi-field coupling mechanisms, the development of low-loss, fast-response LC materials, and practical applications in optical computing, adaptive optics, and beyond, thereby forging a vital bridge between fundamental optics and next-generation integrated photonic technologies.","PeriodicalId":100035,"journal":{"name":"Advanced Physics Research","volume":"5 7","pages":""},"PeriodicalIF":2.8,"publicationDate":"2026-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/apxr.70142","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148534441","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}

Among them, S-type negative differential resistance (NDR) devices offer wide material versatility and strong tunability of their internal dynamics. While nonlinear theory predicts their stability regimes and bifurcations with high accuracy, experimental access to these regimes remains limited. Here, we combine theory and experiment to characterize the stability regimes of an S-type NDR thyristor device exhibiting self-sustained oscillations. By mapping nonlinear control-theoretic concepts onto impedance spectroscopy (IS) measurements, we show that frequency-domain characterization provides direct experimental signatures of stability, bifurcations, and oscillatory regimes, despite the intrinsically nonlinear nature of the system. The measurements further reveal the interaction between autonomous and forced oscillations, as well as entrainment and phase locking phenomena. Our results establish IS as a powerful in situ probe of nonlinear dynamical behavior in oscillatory devices, with direct relevance for neuromorphic and oscillator-based hardware.","PeriodicalId":100035,"journal":{"name":"Advanced Physics Research","volume":"5 7","pages":""},"PeriodicalIF":2.8,"publicationDate":"2026-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/apxr.70141","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148534464","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}

Here, we present a metalens-enabled double-helix point spread function (DH-PSF) for multifunctional imaging, capable of sensing both depth and wavelength information. By superposing Bessel beams with different transverse wave vectors, we design a DH-PSF metalens with two controllable degrees of freedom, whose rotation angle varies linearly with the axial position and the main lobe spacing is inversely proportional to the axial position, significantly enhancing the robustness of depth estimation. Furthermore, the dispersive property of the DH-PSF is deliberately exploited for wavelength sensing, as the lobe spacing exhibits a linear dependence on the incident wavelength at a fixed depth. We experimentally demonstrate single-shot three-dimensional (3D) imaging and wavelength discrimination, with estimation errors maintained below 5%. This work provides new insights into the construction and engineering of DH-PSFs and establishes a compact and versatile framework for 3D imaging and spectral sensing, offering new opportunities for multifunctional imaging devices in machine vision and microscopy.","PeriodicalId":100035,"journal":{"name":"Advanced Physics Research","volume":"5 7","pages":""},"PeriodicalIF":2.8,"publicationDate":"2026-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/apxr.70137","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148533353","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}

Basic concepts of the lattice model with couplings decaying by power law of distance are introduced to frame the underlying theoretical formalism. This review centers on properties of the long-range phase that finds no counterpart in the short-range limit. The breakdown of conformal symmetry in critical regimes and the appearance of massive edge modes differing from conventional Majorana zero modes are discussed. Relevant features including the fractional topological invariant, violations of the area law, and anomalous transport characteristics are also described. Theoretical studies of realistic condensed-matter realizations such as helical Shiba chains, hybrid nanowires, and other platforms are covered to assess their feasibility under various experimental constraints. Finally, experimental efforts are surveyed where implementations in solid-state devices and other systems that can simulate effective long-range topological Hamiltonians are both highlighted.","PeriodicalId":100035,"journal":{"name":"Advanced Physics Research","volume":"5 7","pages":""},"PeriodicalIF":2.8,"publicationDate":"2026-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/apxr.202500240","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148534440","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}

Samples were annealed between 100°C and 400°C to examine thermally induced changes in the crystal structure, morphology, and optical behaviour. X-ray diffraction reveals a temperature-driven transition from a hexagonal CdSeTe phase in the as-prepared and 100°C sample to a mixed hexagonal–cubic structure at 200°C, followed by a complete transformation to a cubic CdTe-rich phase at higher temperatures. The crystallite size increases from 12 nm (as-prepared sample) to 33 nm (400°C sample), indicating thermally assisted structural reorganization. Scanning electron microscopy shows a progression from rod-like particles to irregular agglomerated structures with increasing temperature, while energy-dispersive X-ray spectroscopy confirms the presence of Cd, Se, and Te with uniform elemental distribution. Diffuse reflectance spectra (DRS) indicate enhanced absorption as annealing temperature increases, and bandgaps determined using the Kubelka-Munk method decrease from 2.63 to 2.12 eV up to 300°C, with a slight rise at 400°C due to possible Te loss or compositional shifts. Photoluminescence shows emission peak shifts associated with defect and structural changes.

In the spin-degenerate, spin–orbit—free limit, the reduced Brillouin zone contains flat, spin-degenerate moiré minibands, with periodicity determined by superlattice folding. The inclusion of SOC lifts the spin degeneracy and reduces the effective spectral periodicity by a factor of two. Through SOC, the moiré potential entangles spin, sublattice, and leg degrees of freedom, reshaping the miniband structure in momentum space and generating emergent helicity spectral functions. As the Rashba coupling is renormalized by the moiré pattern, it induces helicity fragmentation, in which the helicity weight is distributed across a dense manifold of moiré minibands, forming an extended network of helicity-carrying states and significantly enhancing helicity fluctuations at the bare-response level. The emergence of Dirac-like miniband crossings at finite SOC demonstrates that moiré heterostructures can support relativistic quasiparticles through band reconstruction. This model provides a microscopic mechanism by which proximity-induced spin–orbit coupling can be amplified via moiré engineering.","PeriodicalId":100035,"journal":{"name":"Advanced Physics Research","volume":"5 7","pages":""},"PeriodicalIF":2.8,"publicationDate":"2026-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/apxr.202600001","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148534465","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}

Here, a universal and straightforward sputtering-based strategy is presented to realize high-quality GaN epitaxial films on Si(111) substrates characterized by exceptionally low vertical resistance, ohmic behavior, and robust thermal stability. This technique centers on the in situ formation of a sub-nanometer (∼0.5 nm) silicide-based template via rapid thermal annealing—a method demonstrating unprecedented versatility across 25 different metallic species. Scanning transmission electron microscopy (STEM) reveals that a unique amorphous-like interlayer (AL-IL) effectively accommodates lattice mismatch and relaxes epitaxial strain. These AL-IL templates further serve as high-performance platforms for metalorganic chemical vapor deposition (MOCVD) overgrowth, successfully bridging the gap between scalable, low-cost fabrication and device-grade vertical performance.","PeriodicalId":100035,"journal":{"name":"Advanced Physics Research","volume":"5 7","pages":""},"PeriodicalIF":2.8,"publicationDate":"2026-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/apxr.70143","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148522861","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}
