06/18/18 : Lieb-Robinson bounds " by Maurizio Fagotti :
06/04/18 : Quantum mechanics in multi-connected space and the origin of new statistics in low dimensional system by Raoul santachiara

We recall how to define the problem of N indinstinguishible quantum particles and argue that the topology of the configuration space plays a crucial role. This observation, that has been put on solid grounds by Leinaas and Mirheim in the 1977, has provided the theoretical framework for the existence of anyonic statistics in two dimensions. Moreover, it inspired the connection between the Conformal field theory and topological phases in two dimensions: via this connection, the occurence of non-Abelian anyons in the fractional quantum Hall effect has been suggested.
