SUMMARY:Séminaire du LPTMS: Leonardo Mazza - LPTMS\, salle 201\, 2ème ét
 age\, Bât 100\, Campus d'Orsay - 12 Juil 16 11:00
DESCRIPTION:Interacting gases with a synthetic gauge field in the synthetic
  dimension\nLeonardo Mazza (Ecole Normale Supérieure / PSL Research Unive
 rsity\, CNRS)\nSynthetic ladders realized with one-dimensional alkaline-ea
 rth(-like) fermionic gases and subject to a gauge field represent a promis
 ing environment for the investigation of quantum Hall physics with ultraco
 ld atoms. We unveil the existence of a hierarchy of fractional insulating 
 and conducting states by means of both analytical bosonization techniques 
 and numerical methods based on the density-matrix renormalization group al
 gorithm. We show that such states can be exploited for constructing a topo
 logical Thouless pump where the charge transported after one cycle is quan
 tized to fractional values and demonstrate this behavior with a full many-
 body time-dependent calculation.\n1 - S. Barbarino\, L. Taddia\, D. Rossin
