原子物理学中的完全流性

Perfect Fluidity in Atomic Physics

Thomas Schaefer

摘要:

用强相互作用的夸克-胶子等离子体解释了在相对论重离子对撞机(RHIC)上获得的实验结果。强相互作用等离子体的特征在于"完美的流动性“,即剪切粘度与熵密度的比率饱和了提议的下限。在这篇文章中,我们探讨了类似的现象发生在一个强耦合的非相对论性费米液体中的费米子之间的散射长度是无限大的可能性。

英文摘要:

Experimental results obtained at the Relativistic Heavy Ion Collider (RHIC) have been interpreted in terms of a strongly interacting quark gluon plasma. The strongly interacting plasma is characterized by ``perfect fluidity'', i.e. a ratio of shear viscosity to entropy density that saturates a proposed lower bound. In this contribution we explore the possibility that a similar phenomenon takes place in a strongly coupled non-relativistic Fermi liquid in which the scattering length between the Fermions is infinitely large.
