SUMMARY:Séminaire exceptionnel du LPTMS: Elia Macaluso - Salle des sémina
 ires du FAST et du LPTMS\, bâtiment Pascal n°530 - 18 Sep 19 11:00
DESCRIPTION:Charge and statistics of lattice quasiholes from density measur
 ements\nElia Macaluso (Università di Trento\, Italy)\nIn the last decades
 \, the lattice counterparts of the fractional quantum Hall effect have att
 racted strong attention. These systems\, generally known as fractional Che
 rn insulators (FCIs)\, support elementary bulk excitations carrying fracti
 onal charge and anyonic statistics.\nIn this context\, I will first introd
 uce the FCI state at filling ν = 1/2 described by the bosonic Harper-Hofs
 tadter model with hard-core interactions. Then\, I will show how the aform
 entioned bulk excitations can be studied by means of a Tree Tensor Network
  (TTN) technique and\, in particular\, how the TTN ansatz for the many-bod
 y state allows us to study relatively large samples (up to N=18 particles 
 on a 16x16 lattice)\, with the experimentally relevant open boundary condi
 tions. Finally\, I will explain how\, not only the fractional charge\, but
  also the anyonic statistics of the FCI excitations can be obtained throug
 h simple density measurements.
