SUMMARY:Exploring anyons and black holes-like dynamics in flatland \, 
 Physics Department Colloquium\, Smitha Vishveshwara\, UIUC
DESCRIPTION:The world and the Universe we live in are composed of ferm
 ions and bosons. The quantum statistics of these particles overwhelmin
 gly governs what we see around us. But one could wonder\, can other ki
 nds of quantum particles exist? I will begin this colloquium with an i
 ntroduction of quantum statistics and the fascinating possible existen
 ce of anyons\, particles which obey 'fractional' statistics.  
\n 
\nT
 he quantum Hall system forms a marvelous two-dimensional realm for hos
 ting many rich phenomena\, including fractional statistics. I will des
 cribe how anyons can emerge in this setting\, how they could be detect
 ed borrowing from beam-splitter and other principles used to detect bo
 sons and fermions\, and how recent landmark experiments did perform su
 ch detection. I will also illustrate how the same setting can probe dy
 namics akin to that found in the astrophysical realm of black holes. S
 pecifically\, point-contact geometries can exhibit phenomena parallel 
 to Hawking-Unruh radiation and black hole quasinormal modes associated
  with ringdowns in gravitational wave detection.
