Idea

In solid state physics a strange metal is a metallic phase of matter which is not described well by Landau's Fermi liquid theory of small perturbations about the Fermi sea.

Known strange metals exhibit topological order in that their ground state has long-range entanglement (a topological phase of matter). Instead of by Fermi liquid theory, strange metals are well described by AdS/CFT in condensed matter physics.
