DESCRIPTION:Speaker: Benjamin Sacépé\nhosted by Georgios Katsaros\nAbstra
 ct: Topological superconductivity has attracted considerable attention due
  to its great promise for fault-tolerant quantum computing. Conventional a
 pproaches rely on intricate hybrid systems combining topological insulator
 s and superconductors\, requiring precise material engineering and fine-tu
 ned conditions\, yet a clear experimental demonstration remains absent to 
 this day. In this colloquium\, I will introduce a novel type of topologica
 l insulator state emerging from the physics of the quantum Hall effect. Th
 is state leverages the unique properties of the zeroth Landau level in gra
 phenea remarkable\, strongly interacting flat band where electron-electron
  interactions give rise to diverse broken-symmetry phases\, characterized 
 by distinct topological and lattice-scale orders. These phases can be iden
 tified through transport measurements [1] and directly visualized using sc
 anning tunneling spectroscopy [2]. I will also demonstrate how superconduc
 tivity can be induced in quantum Hall edge channels to create robust Josep
 hson junctions\, despite the presence of a strong perpendicular magnetic f
 ield [3]\, thus opening a new path toward the realization of topological s
 uperconductivity in quantum Hall Josephson junctions.[1] L. Veyrat et al.
