AI 中文摘要
我们从精确的相空间Kubo-Martin-Schwinger（KMS）关系出发，推导了旋转热平衡中矢量场的广义涨落-耗散定理（FDT）。所得的FDT包含超出标量热因子的旋转诱导张量贡献。在局域输运极限下，我们获得了含旋转的模型无关的广义爱因斯坦关系，其中在热涡度的二阶项上，对称动量扩散依赖于低频谱信息，这些信息超出了旋转依赖的耗散阻力所编码的内容。值得注意的是，我们发现了一个新的爱因斯坦型关系，将谱函数中的零模与非旋转阻力系数联系起来。这些零模构成了重夸克偶素轨道极化的新机制。同一FDT约束导出了修正的细致平衡关系，其一阶涡度修正由跃迁极化决定，而不依赖于热浴模型。我们的发现为研究各领域中旋转量子物质建立了微观平衡约束。
英文摘要
We derive a generalized fluctuation-dissipation theorem (FDT) for vector fields in rotating thermal equilibrium from an exact phase-space Kubo-Martin-Schwinger (KMS) relation. The resulting FDT contains rotation-induced tensorial contributions beyond a scalar thermal factor. In the local transport limit, we obtain a model-independent generalized Einstein relation with rotation in which, through second order in thermal vorticity, symmetric momentum diffusion depends on low-frequency spectral information beyond that encoded in the rotation-dependent dissipative drag. Remarkably, we find a new Einstein-type relation linking zero modes in the spectral function to the nonrotating drag coefficient. These zero modes underlie a new mechanism for the orbital polarization of heavy quarkonium. The same FDT constraint yields a modified detailed-balance relation whose first-order vortical correction is governed by transition polarization, without explicit dependence on the bath model. Our findings establish microscopic equilibrium constraints for studying rotating quantum matter in various fields.
