SUMMARY:Breaking Barriers with Maxwell's Demon\, Physics Department Co
 lloquium\, Mark Raizen\, University of Texas at Austin
DESCRIPTION:In 1871\, James Clerk Maxwell proposed a mythical creature
  that could regulate the motion of gas-phase particles by controlling 
 a gate.  This creature was called Maxwell's demon by Lord Kelvin\, and
  remained a vigorous topic of debate for over 130 years.  The demon se
 emed to violate the Second Law of Thermodynamics\, though it was later
  shown that in principle\, information entropy saves us from that cata
 strophe.  In this talk\, I will describe how we have now realized Maxw
 ell's demon in the laboratory with a self-acting one-way wall\, and ho
 w it enables the control of matter with light.  In particular\, I will
  discuss how Maxwell's demon is being used to break the barriers of La
 ser Cooling\, Isotope Separation and Nanoscience.
