旋转背景下的弦张力与Polyakov圈

String tension and Polyakov loop in a rotating background

Jun-Xia Chen, Sheng Wang, De-Fu Hou, Hai-Cang Ren

AI总结:

该研究利用规范/引力对偶,通过全局与局域两种变换引入旋转,揭示旋转降低重夸克偶素自由能给出的弦张力、提高Polyakov圈确定的禁闭—退禁闭相变温度,且与格点模拟相符。

摘要:

我们通过规范/引力对偶研究旋转对胶动力学中弦张力以及禁闭—退禁闭相变温度的影响。我们探索了两种引入旋转的不同方法,即全局变换和局域变换,并比较所得结果。结果表明,在存在重夸克偶素时由自由能提取的弦张力随角速度增大而减小,而由Polyakov圈确定的相变温度随角速度增大而升高,这与格点模拟结果一致。

英文摘要:

We study the influence of a rotation on the string tension and the temperature of the confinement-deconfinement transition of gluodynamics by gauge/gravity duality. We explore two distinct approaches, global transformation and local transformation, to introduce rotation and compare the results. It is shown that the string tension extracted from the free energy in the presence of a heavy quarkonium decreases with the increasing angular velocity, while the transition temperature determined by the Polyakov loop increases with increasing angular velocity, which is in line with lattice simulations.
