$\text{AdS}_{5}$中的非对称激波碰撞

Asymmetric shockwave collisions in $\text{AdS}_{5}$

Sebastian Waeber, Andreas Rabenstein, Andreas Schäfer, Laurence G. Yaffe

摘要:

在渐近反de Sitter时空中,利用对偶引力公式研究了极大超对称杨-米尔斯理论中的非对称平面激波碰撞。碰撞后的流体动力学流动被发现是非常好的描述对称激波碰撞的结果通过适当的手段。这项研究延伸,不对称碰撞,以前的工作切斯勒,基尔伯特斯,和范德Schee检查特殊情况下的对称碰撞。由于不对称平面碰撞产生的流体动力学流动的普遍描述,人们可以模拟,定量,非平面,非中心碰撞的高度洛伦兹收缩的弹丸,而不需要计算,全息,碰撞的有限大小的弹丸具有非常大的纵横比。本文还包含了一个教学的计算方法和软件的描述,用于计算冲击波碰撞使用伪谱方法,补充Chesler和Yaffe的早期概述。

英文摘要:

Collisions of asymmetric planar shocks in maximally supersymmetric Yang-Mills theory are studied via their dual gravitational formulation in asymptotically anti-de Sitter spacetime. The post-collision hydrodynamic flow is found to be very well described by appropriate means of the results of symmetric shock collisions. This study extends, to asymmetric collisions, previous work of Chesler, Kilbertus, and van der Schee examining the special case of symmetric collisions. Given the universal description of hydrodynamic flow produced by asymmetric planar collisions one can model, quantitatively, non-planar, non-central collisions of highly Lorentz contracted projectiles without the need for computing, holographically, collisions of finite size projectiles with very large aspect ratios. This paper also contains a pedagogical description of the computational methods and software used to compute shockwave collisions using pseudo-spectral methods, supplementing the earlier overview of Chesler and Yaffe.
