SUMMARY:Mott insulators with boundary zeros\, R. G. Herb Condensed Mat
 ter Seminar\, Giorgio Sangiovanni\, Wuerzburg
DESCRIPTION:In the recent literature\, the concept of topological Mott
  insulator has been spelled out in rather different ways. Due to the i
 ntrinsic many-body nature\, a comprehensive classification is challeng
 ing to formulate. In this talk I will discuss a novel\, remarkably sim
 ple way of describing topological Mott insulators based on the momentu
 m dispersion of single-particle Green's function zeros. After focusing
  on the fate of the bulk-boundary correspondence\, I will propose a wa
 y of revealing the physical consequences of the boundary zeros based o
 n the hybridization with conventional topologically protected edge mod
 es. In the final part of the talk I will give an intepretation in term
 s of fractionalized electrons and boundary spinons of a U(1) gapped sp
 in liquid phase.
