AI 中文摘要
我们使用改进全息量子色动力学（IHQCD）模型研究有限θ≠0时SU($N_{c}$)纯杨-米尔斯理论中的禁闭相变。结果表明，对于大但固定的$N_{c}$，临界温度作为θ的函数降低，减少了禁闭相变中的过冷量。禁闭相变完成后，由于有限θ下杨-米尔斯理论的多分支真空结构，可产生畴壁网络。我们强调了产生的畴壁与禁闭相变动力学之间的潜在相互作用。最后，我们展示了通过畴壁湮灭产生引力波有趣印记及其与禁闭相变相互作用所需的微调水平。
英文摘要
We study the confinement phase transition in SU($N_{c}$) pure Yang-Mills theory at finite $θ\neq 0$ using the Improved Holographic QCD (IHQCD) model. We show that the critical temperature, as a function of $θ$ for large but fixed $N_{c}$, is reduced, thus decreasing the amount of supercooling in the confinement phase transition. Upon completion of the confinement phase transition, a network of domain walls can be produced, owing to the multi-branched vacuum structure of Yang-Mills theory at finite $θ$. We highlight the potential interplay between the produced domain walls and the confinement phase transition dynamics. We emphasize that DW production from bubble coalescence in strongly coupled non-conformal FOPTs is a dynamical process of vacuum assignment, hydrodynamics, and local reheating effects, all potentially affecting the approach towards the scaling regime. Lastly, we demonstrate the level of tuning necessary for potentially interesting imprints from gravitational waves through domain wall annihilation and its interplay with the confinement PT.
