SUMMARY:Anyonics: Designing exotic circuitry with non-Abelian anyons\,
  R. G. Herb Condensed Matter Seminar\, Kirill Shtengel\, UC Riverside
DESCRIPTION:<br>
\nNon-Abelian anyons are widely sought for the exotic
  fundamental<br>
\nphysics they harbour as well as for their possible 
 applications for<br>
\nquantum information processing. Currently\, the
 re are numerous<br>
\nblueprints for stabilizing the simplest type of 
 non-Abelian anyon\, a<br>
\nMajorana zero energy mode bound to a vorte
 x or a domain wall. One such<br>
\ncandidate system\, a so-called "Maj
 orana wire" can be made by<br>
\njudiciously interfacing readily avail
 able materials\; the experimental<br>
\nevidence for the viability of 
 this approach is presently emerging.<br>
\nFollowing this idea\, we in
 troduce a device fabricated from<br>
\nconventional fractional quantum
  Hall states\, s-wave superconductors<br>
\nand insulators with strong
  spin-orbit coupling. Similarly to a<br>
\nMajorana wire\, the ends of
  our “quantum wire” would bind<br>
\n"parafermions"\, exotic non-A
 belian anyons which can be viewed as<br>
\nfractionalized Majorana zer
 o modes.<br>
\nI will briefly discuss their properties and describe ho
 w such<br>
\nparafermions can be used to construct new and potentially
  useful<br>
\ncircuit elements which include current and voltage mirro
 rs\,<br>
\ntransistors for fractional charge currents and "flux capaci
 tors".<br>
