SUMMARY:Search for Anyons in Quantum Materials\, Physics Department Co
 lloquium\, Philip Kim\, Harvard University
DESCRIPTION:Anyons\, quasiparticles with fractional charge and exotic 
 exchange statistics\, have inspired decades of condensed matter resear
 ch. Furthermore\, it has been predicted that the exchange braiding of
  these particles\, particularly non-abelian anyons\, could produce top
 ologically protected logic operations that may serve as the building b
 locks of fault-tolerant quantum computing. In this talk\, I will discu
 ss progress in researching two quantum materials platforms for realiz
 ing these exotic particles. In the first example\, we will discuss any
 on braiding arising in fractional quantum Hall (FQH) effects in graphe
 ne\, using quantum Hall interferometers for direct observation of the 
 anyon braiding phase around a confined cavity. In the second example\
 , we will describe our recent experimental efforts to realize non-abel
 ian anyons in proximitized topological insulator surfaces. Using a Cor
 bino device geometry\, we demonstrate the controlled manipulation of 
 non-abelian anyons contained in magnetic vortices. We report tantalizi
 ng experimental observations to show the presence of non-abelian anyon
 s in both systems.
