Abstract: The speaker reviews the progress in last 20-30 years, during which we discovered that there are new states of matter that are beyond Landau symmetry breaking theory, and discuss new 'topological' phenomena, such as topological degeneracy, that reveal the existence of those new phases - topologically ordered phases. Just like zero-viscosity defines the superfluid order, the new 'topological' phenomena define the topological order at macroscopic level. More recently, we found that, at the microscopical level, topological order is due to long-range quantum entanglements, just like fermion superfluid is due to fermion-pair condensation. Long-range quantum entanglements lead to many amazing emergent phenomena, such as fractional quantum numbers, fractional/non-Abelian statistics, and perfect conducting boundary channels.
