AI 中文摘要

旋转是量子色动力学(QCD)物质的关键控制参数,但有效模型和晶格QCD对其对去禁闭转变的影响预测相互矛盾。我们利用全息框架内的旋转-磁对应关系,研究纯胶子物质的旋转响应。通过与虚角速度下的晶格QCD数据校准,发现实旋转增强色磁弦张力并提高去禁闭温度,与晶格QCD解析延拓预测一致。色磁弦张力的温度依赖性主导系统的巴尼特响应。这种反常机制仅在弱实旋转下存在,高温时常规巴尼特行为稳定。结果确立了色磁诱导惯性反转(CII)机制为这种反常旋转响应的微观起源。

英文摘要

Rotation serves as a pivotal control parameter for QCD matter, yet effective models and lattice QCD yield conflicting predictions regarding its effect on the deconfinement transition. Using a rotation-magnetic correspondence within a holographic framework, we investigate the rotational response of pure gluonic matter. Calibrated against lattice QCD data at imaginary angular velocity, we find real rotation enhances chromomagnetic string tension and raises deconfinement temperature, consistent with lattice QCD analytic-continuation predictions. The temperature dependence of chromomagnetic string tension dominates the system's Barnett response: weak low-temperature tension induces the negative Barnett effect, and slightly above the transition, spin contributions prevail to generate an anomalous negative total moment of inertia. Since growing angular velocity further strengthens chromomagnetic string tension and suppresses spin-dominated inversion, this anomalous regime only survives at weak real rotation and vanishes at large angular velocity. At high temperature, fully restored strong string tension stabilizes conventional Barnett behavior. Stemming from the melting and thermal restoration of nonperturbative chromomagnetic flux tubes, our results establish the chromomagnetic-induced inertia inversion (CII) mechanism as the microscopic origin of this anomalous rotational response.
