AI 中文摘要
近期研究表明,格点计算与全息模型在夸克胶子等离子体(QGP)旋转效应上的分歧源于参考框架的不同选择:静态观察者测得的禁闭温度随旋转升高而降低,而共转观察者测得的结果相反,两种结果均正确,理解临界温度的框架依赖性是描述旋转QGP的重要一步。本文通过用最一般的迈尔斯-佩里(Myers-Perry)黑洞解描述等离子体,推广了此前的全息结果,该解打破了此前等角动量情形下的球对称性,因此共转观察者测得的局域温度具有非平凡的角依赖性:当旋转速度升高时,温度可降低、升高甚至呈现非单调行为。
英文摘要
Recently, it was demonstrated that the disagreement between lattice calculations and holographic models, regarding rotational effects in the quark-gluon plasma (QGP), occurs due to different choices of reference frames. While a static observer measures a confinement temperature that decreases with rotation, one in a co-rotating frame finds the opposite behavior. Both results are correct, and a comprehension of the frame-dependency of the critical temperature is a significant step in the description of the QGP under rotation. In this article, we generalize this previous holographic result by describing the plasma through the most general Myers-Perry black hole solution. This breaks the spherical symmetry present in the equal angular momentum case, considered before. As a consequence, the local temperature measured by a co-rotating observer has a non-trivial angular dependence: it can decrease, increase or even behave non-monotonically when rotational velocity increases.
