Nearly Perfect Fluidity in the Dilute Fermi Gas: An Update
摘要:
在这篇文章中,我们总结了最近的强关联稀费米气体的输运性质的结果。本文讨论了流体动力学方程的正相问题,并给出了梯度展开式中二阶项结构的新结果。我们还讨论了从动力学理论的预测,并显示如何使用实验数据椭圆流这些预测可以进行测试。我们总结了目前的限制剪切粘度熵密度比$η/s$。
英文摘要:
In this contribution we summarize recent results on the transport properties of strongly correlated dilute Fermi gases. We discuss the hydrodynamic equations in the normal phase and present new results on the structure of second order terms in the gradient expansion. We also discuss predictions from kinetic theory, and show how these predictions can be tested using experimental data on elliptic flow. We summarize current constraints on the shear viscosity to entropy density ratio $η/s$.
