Description
Entanglement in topological ordered states has so far been
investigated through the perspective of the ground-state
wave function. By presenting entanglement spectra of the
(quasihole) excitations of fractional quantum Hall states, I
will show their typical structure in Abelian, as well as non-
Abelian cases of the Read-Rezayi sequence, including the
realistic Coulomb-interaction ground states that they are
believed to describe. I will argue that the excitation wave
functions contain sufficient information to identify the
system's topological order.
