AI 中文摘要
我们研究了(2+1)维反德西特时空中的一种修正带电BTZ黑洞，其标准几何结构被类 quintessence（ quintessence 是一种暗能量模型）各向异性物质和弦云所包围。对应的度规函数包含了电荷以及两种物质源的效应。光学分析显示，这些源的共同作用产生了稳定的圆形光子轨道，导致光子动力学及相关能量发射出现显著修正。有限空腔中的热力学分析进一步表明，电荷与奇异物质源会显著影响黑洞的局域热稳定性和相结构。这些物质源的共同作用产生了稳定的光子球，以及标准带电BTZ解中不存在的新颖热力学行为。
英文摘要
We study a modified charged BTZ black hole in \((2+1)\)--dimensional anti-de Sitter spacetime, where the standard geometry is surrounded by quintessence-like anisotropic matter and a cloud of strings. The corresponding metric function incorporates the effects of the electric charge and the two matter sources. The optical analysis reveals that their combined influence gives rise to a stable circular photon orbit, leading to distinctive modifications of photon dynamics and the associated energy emission. The thermodynamic analysis in a finite cavity further shows that the electric charge and exotic matter sources significantly affect the local thermal stability and phase structure of the black hole. The combined effects of these matter sources give rise to a stable photon sphere and novel thermodynamic behavior absent in the standard charged BTZ solution.
