SUMMARY:Engineering non-Abelian anyons: Moving beyond Majorana zero modes
DESCRIPTION:Featuring Kirill Shtengel\, UC Riverside\nHosted by: Claudio Ch
	amon\n\nPart of the Biophysics/Condensed Matter Seminar Series.\n\nAbstract
	:\n\nNon-Abelian anyons are widely sought for the exotic fundamental\nphysi
	cs they harbor as well as for their possible applications for\nquantum info
	rmation processing. Currently\, there are numerous\nblueprints for stabiliz
	ing the simplest type of non-Abelian anyon\, a\nMajorana zero energy mode b
	ound to a vortex or a domain wall. One such\ncandidate system\, a so-called
	 "Majorana wire" can be made by\njudiciously interfacing readily available 
	materials; the experimental\nevidence for the viability of this approach is
	 presently emerging.\nFollowing this idea\, we introduce a device fabricate
	d from\nconventional fractional quantum Hall states\, s-wave superconductor
	s\nand insulators with strong spin-orbit coupling. Similarly to a\nMajorana
	 wire\, the ends of our "quantum wire" would bind\n"parafermions"\, exotic 
	non-Abelian anyons which can be viewed as\nfractionalised Majorana zero mod
	es. These modes can be experimentally\nidentified (and distinguished from M
	ajoranas) using tunnelling and\nJosephson measurements.\nI will also descri
	be a practical recipe for braiding parafermions\,\nwhich obey non-Abelian s
	tatistics.
