共形场的发散型理论
Divergence-type theory of conformal fields
摘要：
我们提出了一个非线性流体动力学描述的共形等离子体的发散型理论（DTTs）的框架内，这不是基于梯度展开。我们比较的DTT和二阶理论（基于共形不变量）的方程，Bjorken ow的情况下。在DTT中接近理想流体动力学的速度更快，表明我们的结果可以用于相对论重离子碰撞的早期动力学研究。
英文摘要：
We present a nonlinear hydrodynamical description of a conformal plasma within the framework of divergence-type theories (DTTs), which are not based on a gradient expansion. We compare the equations of the DTT and the second-order theory (based on conformal invariants), for the case of Bjorken ow. The approach to ideal hydrodynamics is faster in the DTT, indicating that our results can be useful in the study of early-time dynamics in relativistic heavy-ion collisions.
