摘要:

本研究通过基于求解完全协变矢量玻色子方程的分析方法,研究了扭曲石墨烯纳米带(TGNRs)中光子模式的行为。我们提出了一个模型,展示了TGNRs中的螺旋扭曲如何显著影响光子模式的演化。我们的解析解给出了模式轮廓、能谱和衰减特性的详细表达式。我们发现,增大扭曲参数会缩短阻尼模式的衰减时间(\\(τ_{ns}\\)),表明扭曲几何结构增强了光子耦合。相反,较长的纳米带(NRs)表现出更长的衰减时间,显示出长度(\\(L\\))依赖效应,其中\\(τ_{ns} \propto L / c\\),\\(c\\)代表光速。这些发现可能增进对纳米结构中光调控的理解,并表明在可调谐光子器件、拓扑光子学和量子光学系统中具有潜在应用。

英文摘要:

This study investigates the behavior of photonic modes in twisted graphene nanoribbons (TGNRs) using an analytical approach based on solving the fully covariant vector boson equation. We present a model that demonstrates how helical twisting in TGNRs significantly affects the evolution of photonic modes. Our analytical solutions yield detailed expressions for mode profiles, energy spectra, and decay characteristics. We find that increasing the twist parameter shortens the decay times (\(τ_{ns}\)) for damped modes, indicating enhanced photonic coupling due to the twisted geometry. Conversely, longer nanoribbons (NRs) exhibit increased decay times, showing a length (\(L\))-dependent effect, where \(τ_{ns} \propto L / c\), with \(c\) representing the speed of light. These findings may enhance the understanding of light control in nanostructures and suggest potential applications in tunable photonic devices, topological photonics, and quantum optical systems.
