The manipulation of topological electronic states is a key scientific challenge in the development of next-generation quantum devices. In this work, we propose a universal topological engineering strategy based on magnetic symmetry control, realized via van der Waals heterostructures of rare-earth nitrides and an inert GaS spacer, denoted as XN₂/GaS/XN₂ (X = Gd, Tb, Dy, Ho, Tm, Er). This platform enables programmable topological phase transitions between ferromagnetic quantum spin Hall insulators (QSHIs) and antiferromagnetic quantum anomalous Hall insulators (QAHIs). By continuously tuning the in-plane magnetization direction, the Berry curvature distribution is effectively modulated, inducing periodic transitions between topologically trivial and nontrivial states. Taking ErN₂/GaS/ErN₂ as a representative system, we track the evolution of the Chern number and ℤ₂ invariant with magnetization orientation, demonstrating a reversible switching between QSHI and QAHI phases. The same mechanism is found to operate across the full series of XN₂/GaS/XN₂ heterostructures, establishing its generality. These results offer both a robust theoretical framework and a practical material platform for the magnetization-controlled realization of quantum spin and anomalous Hall phases in two-dimensional magnetic van der Waals systems, paving the way for reconfigurable topological devices.

拓扑电子态的操纵是下一代量子器件发展的关键科学挑战。在这项工作中，我们提出了一种基于磁对称控制的通用拓扑工程策略，该策略通过稀土氮化物的范德华异质结构和惰性气体间隔剂XN2/GaS/XN2 （X = Gd, Tb, Dy, Ho, Tm, Er）来实现。该平台实现了铁磁量子自旋霍尔绝缘体（QSHIs）和反铁磁量子反常霍尔绝缘体（QAHIs）之间的可编程拓扑相变。通过不断调整平面内磁化方向，可以有效地调制Berry曲率分布，诱导拓扑平凡和非平凡状态之间的周期性转换。以ErN2/GaS/ErN2为代表系统，我们跟踪了陈氏数和2不变量随磁化方向的演化，证明了QSHI和QAHI相之间的可逆切换。在XN2/GaS/XN2异质结构的整个系列中发现了相同的机制，建立了其普遍性。这些结果为二维磁性范德华体系中量子自旋和反常霍尔相的磁化控制实现提供了一个强大的理论框架和实用的材料平台，为可重构拓扑器件铺平了道路。

A comprehensive approach for simulating lasing dynamics in a liquid crystal based laser is presented. The approach takes into account the transformation of the liquid crystal structure caused by applied voltage. In particular, it allows us to explicitly account for a resonant mode frequency shift in the laser equations. The laser dynamic is described by a set of coupled non-linear differential equations for dye polarizations, population densities and the electromagnetic fields. The proposed model is applied to a photonic crystal - metal microcavity filled with a resonant nematic liquid crystal layer doped with a dye. The calculated lasing spectra governed by external electric field are verified in comparison with measured spectra.

The study of electron acoustic waves (EAWs) and their associated solitary structures in semiconductor quantum plasma doped with nanoparticle clusters has been carried out. The system consists of cold and hot electrons, holes, and stationary ions. The theory has been built using the quantum hydrodynamic (QHD) model. The dispersion relation for EAWs has been set up. To explore nonlinear behaviour, the perturbation technique has been applied, leading to the Korteweg de Vries (KdV) equation. The analysis demonstrates that quantum effects stabilize wave propagation at higher frequencies, while the presence of nanoparticles strongly influence wave dispersion at higher frequencies. Nonlinear analysis shows that solitons in quantum plasma attain higher amplitudes and broader structures due to quantum effects and with the inclusion of nanoparticles.

Constructing two-dimensional van der Waals magnetic tunnel junctions with the giant tunneling magnetoresistance effect is crucial towards miniaturized spintronic devices. Herein, we introduce a two-dimensional van der Waals magnetic tunnel junction based on the VSi₂N₄ half-metal and the Janus MoSiGeN₄ semiconductor material, and comprehensively investigate the spintronic transport properties by using density functional theory combined with the non-equilibrium Green's function method. A spin filtering efficiency close to 100% is achieved for the VSi₂N₄/MoSiGeN₄/VSi₂N₄ magnetic tunnel junction with a parallel magnetic configuration, and, surprisingly, a large tunnel magnetoresistance ratio is obtained. Due to the intrinsic dipole moment of Janus MoSiGeN₄, a large tunnel dipole-induced resistance ratio of 6999% is observed in the VSi₂N₄/bilayer-MoSiGeN₄/VSi₂N₄ van der Waals magnetic tunnel junction at zero bias voltage, and it can be further improved by tuning the bias voltage. Importantly, the high spin filtering efficiency and the large tunneling magnetoresistance ratios are maintained throughout the entire bias voltage range. The large tunneling magnetoresistance effect is attributed to the absence of electron states in both spin-conducting channels near the Fermi level in the antiparallel magnetic configuration. Subsequently, we classify the six distinct magnetic and electric combinations of the magnetic tunnel junctions into four distinguishable storage states. Multilevel data storage is thereby achieved through the cooperative control of magnetic and electrical switching. We demonstrate that the VSi₂N₄/MoSiGeN₄/VSi₂N₄ and VSi₂N₄/bilayer-MoSiGeN₄/VSi₂N₄ van der Waals magnetic tunnel junctions are promising candidates for next-generation spintronic devices.

构建具有巨大隧道磁阻效应的二维范德华磁隧道结是实现自旋电子器件小型化的关键。本文引入了基于VSi2N4半金属和Janus MoSiGeN4半导体材料的二维范德华磁隧道结，并利用密度泛函理论结合非平衡格林函数方法全面研究了自旋电子输运性质。对于具有平行磁结构的VSi2N4/MoSiGeN4/VSi2N4磁隧道结，实现了接近100%的自旋滤波效率，并且令人惊讶的是，获得了较大的隧道磁电阻比。由于Janus MoSiGeN4的本征偶极矩，在零偏置电压下，VSi2N4/双层-MoSiGeN4/VSi2N4范德华磁隧道结的隧道偶极感应电阻率高达6999%，通过调整偏置电压可以进一步提高该电阻率。重要的是，在整个偏置电压范围内保持了高自旋滤波效率和大的隧道磁阻比。大的隧穿磁阻效应归因于在反平行磁构型中，两个自旋导电通道在费米能级附近缺乏电子态。随后，我们将磁隧道结的六种不同的磁和电组合分为四种可区分的存储状态。通过磁开关和电开关的协同控制，实现了多级数据存储。我们证明了VSi2N4/MoSiGeN4/VSi2N4和VSi2N4/双层-MoSiGeN4/VSi2N4范德华磁隧道结是下一代自旋电子器件的有希望的候选材料。

Magnonics-based hybrid quantum systems have emerged as a critical platform for investigating diverse quantum correlation phenomena. In this paper, we propose a cavity-magnon optomechanical hybrid system integrated with a coherent feedback loop to enhance quantum correlations. Unlike previous schemes, GHz-band magnon and MHz-band mechanical modes in our proposal are not directly coupled, enabling the easier independent quantum control over subsystems. Moreover, the theoretical analysis and numerical simulations illustrate that the introduced feedback loop can not only significantly amplify quantum correlations but also enhance thermal stability relative to conventional configurations. Such enhancement of quantum correlations may pave the way for advancements in quantum precision measurement and quantum communication technologies.

基于磁振子的混合量子系统已经成为研究各种量子相关现象的关键平台。在本文中，我们提出了一个集成了相干反馈回路的腔-磁振子光力学混合系统来增强量子相关性。与以前的方案不同，在我们的方案中，ghz频段的磁振子和mhz频段的机械模式不是直接耦合的，从而更容易对子系统进行独立的量子控制。此外，理论分析和数值模拟表明，与传统结构相比，引入反馈回路不仅可以显著增强量子相关性，而且可以提高热稳定性。这种量子相关性的增强可能为量子精密测量和量子通信技术的进步铺平道路。

The thermosolutal convection in an inclined porous medium using a local thermal non-equilibrium (LTNE) model with chemical reaction is investigated, which has valuable applications in geophysical and industrial sectors, particularly in subsurface energy extraction and chemical processing. Linear and nonlinear analyses are employed to study the stability of the system. Linear instability is examined through the normal mode, nonlinear stability is analyzed using the energy method by constructing a generalized energy functional. The bvp4c routine in MATLAB R2023a is used to solve the eigenvalue problem. The study evaluates the effect of non-dimensional parameters, including the porosity-modified conductivity ratio (τ), the Damkohler number (Dm), the inter-phase heat transfer parameter (H), the Lewis number (Le), and the solutal Rayleigh number (Rs). The results from this study show that, increasing the inclination angle, Le, and H, increases the critical thermal Rayleigh number, enhancing system stability. On the other hand, the Damkohler number destabilizes the fluid flow. A noteworthy observation is that the suppression of transverse roll structure is governed by the magnitude of the Le. Additionally, while the increase in Le and Rs, the critical Rayleigh value increases in the linear case but decreases in the nonlinear case, which causes the subcritical region to expand.

We present a comparative investigation of plasmon-enhanced photoluminescence (PL) and surface-enhanced Raman scattering (SERS) in gold and silver nanohole arrays (AuNA and AgNA) integrated within a metal–insulator–metal (MIM) configuration and further decorated with silver nanoparticles (AgNPs). The MIM architecture, composed of an Ag buffer layer, a SiO₂ spacer, and a top Au or Ag nanohole film, supports strong vertical coupling of plasmonic modes confined within the dielectric gap, enabling efficient field localization and exciton–plasmon interaction. The nanostructures were fabricated via colloidal lithography and validated by finite-element simulations. AgNA exhibited stronger near-field confinement, yielding the highest absolute PL enhancement (4.93 × over glass) and pronounced SERS response of rhodamine 6G (R6G). In contrast, AuNA showed weaker absolute signals but achieved a larger relative PL gain (1.96 vs. 1.59 for AgNA) after AgNP growth, attributed to hybridization-induced redshifts improving spectral overlap with the 4-(Dicyanomethylene)-2-t-butyl-6-(1,1,7,7-tetramethyljulolidyl-9-enyl)-4H-pyran (DCJTB) emission. Time-resolved PL measurements revealed shortened fluorophore lifetimes for both arrays, which were further reduced by AgNP decoration, confirming enhanced radiative decay through MIM-assisted plasmon–exciton coupling. These findings elucidate the complementary roles of material damping and MIM hybridization in tuning resonance behavior and provide design insights for plasmonic and optoelectronic applications.

我们提出了一个比较研究等离子体增强光致发光（PL）和表面增强拉曼散射（SERS）的金和银纳米孔阵列（AuNA和AgNA）集成在金属-绝缘体-金属（MIM）结构中，并进一步装饰银纳米粒子（AgNPs）。MIM结构由Ag缓冲层、SiO2间隔层和顶部Au或Ag纳米孔膜组成，支持被限制在介电间隙内的等离子体模式的强垂直耦合，实现高效的场定位和激子-等离子体相互作用。采用胶体光刻技术制备了纳米结构，并进行了有限元模拟验证。AgNA表现出更强的近场约束，产生最高的绝对PL增强（比玻璃高4.93倍）和明显的罗丹明6G （R6G）的SERS响应。相比之下，AuNA表现出较弱的绝对信号，但在AgNP生长后获得了较大的相对PL增益（1.96 vs. AgNA为1.59），这是由于杂交诱导的红移改善了与4-（二氰乙烯）-2-t-丁基-6-（1,1,7,7-四甲基朱酰基-9-烯基）- 4h -吡喃（DCJTB）发射的光谱重叠。时间分辨PL测量显示，两种阵列的荧光团寿命都缩短了，AgNP修饰进一步缩短了荧光团寿命，证实了mim辅助等离子体-激子耦合增强了辐射衰减。这些发现阐明了材料阻尼和MIM杂化在调谐共振行为中的互补作用，并为等离子体和光电子应用提供了设计见解。

The simulation result shows that phase matching for the 179^th harmonic (2.26nm) is achieved by compensating the positive dipole phase with negative plasma and geometric phase shifts through laser divergence control. The relative conversion efficiency can be higher than 91% of the value with the ideal phase-matching condition.

We investigate the spin-wave dynamics in concentric magnetic nanotori through micromagnetic simulations under perpendicular pulsed magnetic fields, using the free software MuMax3. These 3D nanostructures can host homochiral and heterochiral vortex configurations, whose spin-wave spectra strongly depend on the magnetostatic coupling parameter δ. In homochiral systems, resonance modes converge as δ increases, while in heterochiral systems, they diverge. Two distinct modes are identified: one associated with the outer surfaces of the tori and another with the inner torus. A central result is the demonstration of reversible transitions between homochiral and heterochiral vortex states using oscillating magnetic fields.

利用免费软件MuMax3，对垂直脉冲磁场下同心磁纳米环中的自旋波动力学进行了微磁模拟。这些三维纳米结构可以具有同手性和异手性涡旋构型，其自旋波谱强烈依赖于静磁耦合参数δ。在同手性体系中，共振模式随着δ的增大而收敛，而在异手性体系中，共振模式则发散。确定了两种不同的模式：一种与环面外表面相关，另一种与内环面相关。一个中心结果是用振荡磁场证明了在同手性和异手性涡旋态之间的可逆转变。开关行为和谐振特性随耦合参数δ的变化而变化，揭示了系统的动态通用性。这种可调的手性控制使同心纳米环成为未来自旋电子器件的有希望的候选器件，为磁逻辑、非易失性存储器和神经形态架构提供了新的机会。这项工作增强了三维磁几何与动态控制的集成，为拓扑信息处理和可重构磁计算的应用铺平了道路。

In this study we obtain interior solutions and investigate structural properties of isotropic compact stars in the framework of four-dimensional regularized Einstein-Gauss-Bonnet (4DEGB) gravity. For stellar matter content, we adopt a widely used quark-matter model that approximates a realistic equation of state (EoS). By numerically integrating the modified Tolman-Oppenheimer-Volkoff equations, we obtain interior solutions for static, spherically symmetric fluid spheres. The resulting sequences are compared directly with the predictions of General Relativity (GR). Our analysis focuses on three diagnostic indicators: (i) the mass-radius profiles under GR and three representative choices of the Gauss-Bonnet coupling; (ii) the stellar compactness factor, C ≡ M/R; and (iii) the relation between stellar mass and central energy density. Recent observational studies suggest that the maximum masses inferred from the mass-radius relation may be larger than previously expected. To address this, we include a comparative set of constraints from multi-messenger astrophysical observations, including gravitational-wave event GW190814, as well as X-ray measurements from NICER for PSR J0740+6620 and PSR J0030+0451. These data provide stringent, astrophysically grounded tests of the viability of the models discussed here. Our results indicate that compact stars within 4DEGB gravity are systematically less compact and achieve moderately higher maximum masses compared to the GR case. This trend is consistent with recent theoretical analyses of compact stars in higher-curvature gravity theories and with constraints from multi-messenger astrophysics. Together, these findings suggest that regularized Gauss-Bonnet corrections constitute a plausible extension of GR in the strong-field regime.

本文在四维正则einstein - gas - bonnet （4DEGB）引力框架下，研究了各向同性致密星的内部解和结构性质。对于恒星物质含量，我们采用了一种广泛使用的夸克-物质模型，该模型近似于现实的状态方程（EoS）。通过对修正的Tolman-Oppenheimer-Volkoff方程进行数值积分，得到了静力球对称流体球的内部解。结果序列直接与广义相对论（GR）的预测进行比较。本文重点分析了三个诊断指标：(1)GR下的质量半径分布和高斯-邦纳耦合的三种代表性选择；（ii）恒星紧凑系数C ≡ M/R；(3)恒星质量与中心能量密度的关系。最近的观测研究表明，从质量-半径关系推断出的最大质量可能比先前预期的要大。为了解决这个问题，我们包括了一组来自多信使天体物理观测的比较约束，包括引力波事件GW190814，以及NICER对PSR J0740+6620和PSR J0030+0451的x射线测量。这些数据为这里讨论的模型的可行性提供了严格的、基于天体物理学的检验。我们的研究结果表明，与GR情况相比，重力在4DEGB以内的致密恒星系统上更不致密，最大质量也更高。这一趋势与最近在高曲率引力理论中对致密恒星的理论分析以及多信使天体物理学的约束是一致的。总之，这些发现表明，正则化高斯-博内修正构成了强场状态下广义相对论的合理扩展。
