SUMMARY:ICFO | FLORIE MESPLE
CLASS:PUBLIC
DESCRIPTION:2-Dimentional stacks are versatile platforms that host many cor
 related phases. Some of these exotic phases not only rely on electronic co
 rrelations but also the non-trivial topology of the bands of these systems
 . This is the case in twisted bilayers of graphene (TBLG)\, for the orbita
 l magnet state for example [1]&nbsp\;\; or in twisted MoTe2\, in which top
 ology expresses with the apparition of the fractional quantum anomalous Ha
 ll effect [2]. I will discuss how it is possible to access this non-trivia
 l topology with scanning tunneling microscopy\, using the atomic-scale loc
 al density of states (LDOS) of 2D materials as a topological observable. I
  will present two different approaches to tackle this&nbsp\;: exploiting t
 he energy dependence of the LDOS in tMoTe2\, or using defects to create in
 terferograms in tBLG.  [1] Lu. X et al. Nature 574 (2019) 653 [2] H. Parks
