 -optical analogue of the event horizon: Hawking radiation and backreaction
 "\n\nABSTRACT: \nHawking radiation - the emission of quantum particles at
  the event horizon of a black hole - connects gravity with quantum mechani
 cs and thermodynamics\; the Bekenstein-Hawking entropy has been the benchm
 ark for potential quantum theories of gravity. But Hawking radiation has n
 ever been observed in astronomy\, only in laboratory analogues and the cha
 nces of ever observing it in space are astronomically small. The energy of
  Hawking radiation must come from the gravitational field around the black
  hole\, but how field quanta generate Hawking quanta has been unknown. In 
 this talk I  report on experimental and theoretical evidence for the proc
 ess that generates Hawking radiation in a fibre-optical analogue of the ev
 ent horizon. There\, as in gravity\, it has been believed that Hawking rad
 iation comes from a complicated\, cascaded process\, but we have found a s
 imple\, direct process and measured its backreaction on the field. Our fin
 dings suggest an equally direct process for other laboratory analogues and
  perhaps also for gravitational fields\, shedding light on how black holes
  might radiate. \n\nBIO: \nUlf Leonhardt joined the Weizmann Institute o
 f Science as Professor of Physics in November 2012 after an international 
 career. Ulf Leonhardt was born in Schlema\, in former East Germany\, on Oc
 tober 9th 1965. He studied physics at Friedrich-Schiller University Jena\,
  at Moscow State University and at Humboldt University Berlin where he rec
 eived his PhD in 1993. He was a Visiting Scholar at the Oregon Center for 
 Optics in the US\, a Habilitation Fellow at the University of Ulm in Germa
 ny and a Göran-Gustafson and Feodor-Lynen fellow at the Royal Institute o
 f Technology in Stockholm\, Sweden. From 2000 to 2012\, he was the Chair i
 n Theoretical Physics at the University of St Andrews\, UK. Ulf Leonhardt 
 also had various visiting positions: in 2008 he was a visiting professor a
 t the National University of Singapore and in 2011 at the University of Vi
 enna\; in 2012/13 he was an adjunct professor at South China Normal Univer
 sity\, fsince 2026 he is a Global Fellow and visiting professor at Vienna 
 Institute of Technology. \n \nUlf Leonhardt is the first from former Eas
 t Germany to receive the Otto Hahn Award of the Max Planck Society. For hi
 s PhD thesis he received the Tiburtius Prize of the Senate of Berlin. In 2
 006 Scientific American listed him among the top 50 policy\, business and 
 research leaders of the world of that year. In 2008 he received a Royal So
 ciety Wolfson Research Merit Award and in 2009 a Theo Murphy Blue Skies Aw
 ard of the Royal Society. In 2012 he received a thousand-talent award of C
 hina. He is a Fellow of the Institute of Physics and of the Royal Society 
 of Edinburgh.
