question: Brian Schmidt won the 2011 Nobel Prize in Physics with which  physics at the University of California, Berkeley?
answer: Saul Perlmutter
context: Title: Adam Riess
  Passage: Adam Guy Riess (born December 16, 1969) is a U.S. astrophysicist and Bloomberg Distinguished Professor at Johns Hopkins University and the Space Telescope Science Institute and is known for his research in using supernovae as cosmological probes.  Riess shared both the 2006 Shaw Prize in Astronomy and the 2011 Nobel Prize in Physics with Saul Perlmutter and Brian P. Schmidt for providing evidence that the expansion of the universe is accelerating.
  Title: Brian Schmidt
  Passage: Brian Paul Schmidt {'1': ", '2': ", '3': 'AC, FRS, FAA', '4': "} (born on 24 February 1967 in Missoula, Montana) is the Vice-Chancellor of the Australian National University (ANU).  He was previously a Distinguished Professor, Australian Research Council Laureate Fellow and astrophysicist at the University's Mount Stromlo Observatory and Research School of Astronomy and Astrophysics.  He is known for his research in using supernovae as cosmological probes.  He currently holds an Australia Research Council Federation Fellowship and was elected a Fellow of the Royal Society (FRS) in 2012.  Schmidt shared both the 2006 Shaw Prize in Astronomy and the 2011 Nobel Prize in Physics with Saul Perlmutter and Adam Riess for providing evidence that the expansion of the universe is accelerating, making him the only Montana-born Nobel laureate.
  Title: Saul Perlmutter
  Passage: Saul Perlmutter (born September 22, 1959) is a U.S. astrophysicist at the Lawrence Berkeley National Laboratory and a professor of physics at the University of California, Berkeley.  He is a member of the American Academy of Arts & Sciences, and was elected a Fellow of the American Association for the Advancement of Science in 2003.  He is also a member of the National Academy of Sciences.  Perlmutter shared the 2006 Shaw Prize in Astronomy, the 2011 Nobel Prize in Physics, and the 2015 Breakthrough Prize in Fundamental Physics with Brian P. Schmidt and Adam Riess for providing evidence that the expansion of the universe is accelerating.
  Title: 2011 Nobel Prize in Physics
  Passage: The 2011 Nobel Prize in Physics was awarded in 2011.  One half of it was awarded to Saul Perlmutter, head of the Supernova Cosmology Product at the Lawrence Berkeley National Laboratory, and the other half was awarded to Brian P. Schmidt and Adam G. Riess, both leaders of the High-Z Supernova Team.  Their prize was awarded "for the discovery of the accelerating expansion of the Universe through observations of distant supernovae."
