标题： Extreme softening of QCD phase transition under weak acceleration: first principle Monte Carlo results for gluon plasma

摘要： 我们使用第一性原理数值蒙特卡罗模拟研究了在弱加速度作用下的胶子等离子体的性质。 我们利用Luttinger（Tolman-Ehrenfest）对应关系，将温度梯度与引力场联系起来，在虚时形式中施加加速度。 在加速度作用下，系统处于全局热平衡状态。 我们的结果表明，即使是最弱的加速度达到$a \simeq 27$ MeV也会显著软化禁闭相变，将静态系统的首阶相变转化为加速胶子的平滑交叉。 加速环境可能与早期宇宙的最初时刻以及相对论重离子碰撞中的初始胶浆区域相关。 特别是，我们的结果表明，如果存在加速度，可能会抑制从夸克-胶子等离子体到强子相的热力学相变的检测。 显示英文摘要

摘要： We study the properties of gluon plasma subjected to a weak acceleration using first-principle numerical Monte Carlo simulations. We use the Luttinger (Tolman-Ehrenfest) correspondence between temperature gradient and gravitational field to impose acceleration in imaginary time formalism. Under acceleration, the system resides in global thermal equilibrium. Our results indicate that even the weakest acceleration up to $a \simeq 27$ MeV drastically softens the deconfinement phase transition, converting the first-order phase transition of a static system to a soft crossover for accelerating gluons. The accelerating environment can be relevant to the first moments of the early Universe and the initial glasma regime of relativistic heavy ion collisions. In particular, our results imply that the acceleration, if present, may also inhibit the detection of the thermodynamic phase transition from quark-gluon plasma to the hadronic phase.
