AI 中文摘要
阻挫量子物质可呈现源于对称性相关低能态的交织序，但仅静态序参量无法揭示竞争构型间涨落的组织方式。本文测量了具有三个谷间可调偏置的p轨道三角晶格超流体中模式分辨的逐次 shot-to-shot 粒子数涨落，观测到随偏置变化的演化：从两个少数谷增强的反关联涨落，到选定双谷条纹相中相对粒子数涨落的强约束。主导涨落结构由包含凝聚模间相互作用的有效正则模型捕获，支持对相干三谷凝聚体的准平衡描述。数据与模型共同揭示了由对隧穿诱导的数-相动力学塑造的量子-热 regime，其中相对相位 scramble 软化了少数谷 regime 的有效势垒，而相位刚性在条纹相中产生宏观谐波约束。本文结果确立了模式分辨涨落测量作为阻挫量子流体中隐藏数-相反作用的探测手段。
英文摘要
Frustrated quantum matter can host intertwined orders rooted in symmetry-related low-energy landscapes, yet static order parameters alone do not reveal how fluctuations are organized among competing configurations. Here we measure mode-resolved shot-to-shot population fluctuations in a $p$-orbital triangular-lattice superfluid with a tunable bias among three valleys. We observe a bias-tuned evolution from enhanced, anticorrelated fluctuations of two minority valleys toward strong confinement of relative-population fluctuations in a selected two-valley stripe phase. The dominant fluctuation structure is captured by an effective canonical model that includes interactions among the condensed modes, supporting a quasi-equilibrium description of the coherent three-valley condensate. Together, the data and model reveal a quantum--thermal regime shaped by pair-tunneling-induced number--phase dynamics, in which relative-phase scrambling softens effective barriers in the minority-valley regime, while phase rigidity gives rise to macroscopic harmonic confinement in the stripe phase. Our results establish mode-resolved fluctuation measurements as a probe of hidden number--phase back-action in frustrated quantum fluids.
