Abstract

We investigate the Dirac oscillator in the spacetime of a spinning cosmic string in the presence of a uniform magnetic field and an Aharonov–Bohm flux, obtaining exact analytical solutions for the relativistic spectrum and wave functions. The combined effects of curvature, rotation, and electromagnetic flux produce controllable shifts in the effective angular momentum and in the localization properties of the states. We compute the Shannon entropies in coordinate and momentum spaces and show that the geometric and topological parameters act as tunable resources for manipulating quantum uncertainty and information distribution in relativistic systems. Our results reveal how nontrivial spacetime backgrounds can be exploited to engineer quantum–information-relevant features, offering new pathways for relativistic quantum control and entropy-based quantum diagnostics.

在宇宙弦拓扑缺陷与狄拉克振荡器（自旋为1/2）相互作用的情况下测试信息熵的影响

我们研究了均匀磁场和Aharonov-Bohm通量存在下自旋宇宙弦的时空中的狄拉克振子，得到了相对论谱和波函数的精确解析解。曲率、旋转和电磁通量的共同作用使有效角动量和态的局域化特性发生了可控的变化。我们计算了坐标空间和动量空间中的香农熵，并表明几何和拓扑参数是操纵相对论系统中量子不确定性和信息分布的可调资源。我们的研究结果揭示了如何利用非平凡时空背景来设计量子信息相关的特征，为相对论量子控制和基于熵的量子诊断提供了新的途径。
