AI总结:

该研究探讨了洛伦兹违反虫洞中无质量自旋1场的传播,通过推导Schrodinger型方程和折射率分布,揭示了虫洞作为非均匀光学介质的特性,并建立了与螺旋面的几何对应关系。

摘要:

我们研究了一个静态、圆对称的(2+1)维虫洞中无质量自旋1场的传播,该虫洞的空间洛伦兹违反各向异性由喉部半径a和变形参数η表征。该几何结构无视界,测地完整,且渐近平坦,具有负高斯曲率,局部化在喉部附近。利用完全协变矢量玻色子形式和协变麦克斯韦理论,我们推导出一个精确的Schrodinger型径向方程,带有曲率诱导的有效势。将动力学转换为Helmholtz形式,得到一个有效的折射率分布,表明虫洞作为非均匀光学介质,具有位置依赖的折射率和频率依赖的限制,其中低频模式被强烈限制,而高频模式几乎自由传播。通过1/[a²(1-η)] ↔ w²建立与螺旋面的微分几何对应,证明洛伦兹违反诱导的曲率在数学上等同于由几何扭转产生的曲率,并将模型与扭转石墨烯纳米带作为类引力平台联系起来。这些结果提供了一个几何框架,用于在拓扑非平凡的(2+1)维背景下,由曲率驱动的局部化、色散和各向异性波传播。

英文摘要:

We study massless spin-1 field propagation in a static, circularly symmetric $(2+1)$-dimensional wormhole with spatial Lorentz-violating anisotropy characterized by the throat radius $a$ and deformation parameter $η$. The geometry is horizon-free, geodesically complete, and asymptotically flat, with negative Gaussian curvature localized near the throat. Using the fully covariant vector boson formalism and covariant Maxwell theory, we derive an exact Schrödinger-type radial equation with a curvature-induced effective potential. Recasting the dynamics in Helmholtz form yields an effective refractive-index profile, showing that the wormhole acts as an inhomogeneous optical medium with position-dependent refractive index and frequency-dependent confinement, where low-frequency modes are strongly trapped while high-frequency modes propagate almost freely. A differential-geometric correspondence with helicoidal surfaces is established via $1/[a^2(1-η)] \leftrightarrow w^2$, demonstrating that Lorentz-violation-induced curvature is mathematically equivalent to curvature generated by geometric twist and linking the model to twisted graphene nanoribbons as analog-gravity platforms. These results provide a geometric framework for curvature-driven localization, dispersion, and anisotropic wave propagation in topologically nontrivial $(2+1)$-dimensional backgrounds.
