    What can we do with a quantum liquid?


    2017 Kay Malmstrom Lecture in Physics

    Guest LecturerAnthony J. Leggett, Ph.D.
    John D. and Catherine T. MacArthur Professor of Physics
    University of Illinois at Urbana-Champaign

    Quantum liquids are physical systems that display the effects not only of quantum mechanics but also those of quantum statistics—that is, of the characteristic indistinguishability of elementary particles. The most spectacular manifestations of quantum statistics are the phenomena of
    Bose-Einstein condensation and the closely related Cooper pairing; in both cases, a finite fraction of all the particles in the system are forced to all do exactly the same thing at the same time, and, as a result, effects that would normally be obscured by thermal noise may become visible, sometimes spectacularly so. I will review some examples of such behavior in degenerate alkali gases, superconductors, and superfluid helium-3.

    About Anthony J. Leggett

    Anthony J. Leggett was born in London, England, in March 1938. He attended Balliol College in Oxford, where he majored in Literae Humaniores (classical languages and literature, philosophy, and Greco-Roman history), and thereafter Merton College in Oxford, where he took a second undergraduate degree in physics. He completed a Ph.D. in theoretical physics under the supervision of D’ter Haar. After postdoctoral research in Urbana, Kyoto, and elsewhere, he joined the faculty of the University of Sussex (UK) in 1967, being promoted to Reader in 1971 and to Professor in 1978. In 1983, he became John D. and Catherine T. Macarthur Professor at the University of Illinois at Urbana-Champaign, a position he currently holds. His principal research interests lie in the areas of condensed matter physics, particularly high-temperature superconductivity, and the foundations of quantum mechanics. Professor Leggett is a member of the Royal Society (1980), American Philosophical Society (1991), American Academy of Arts and Sciences (1996), National Academy of Sciences (1997) and a foreign member of the Russian Academy of Sciences (1999), a fellow of the Institute of Physics and the American Physical Society, and an honorary fellow of the Institute of Physics (UK) (1999). Professor Leggett has received numerous awards, including the Maxwell Medal and Prize (Institute of Physics, UK), 1975; Fritz London Memorial Award, 1981; Simon Memorial Prize, 1981; Paul Dirac Medal and Prize (Institute of Physics, UK), 1992; John Bardeen Prize (with G.M. Eliashberg) (M2S), 1994; Eugene Feenberg Memorial Medal, 1999; Wolf Prize in Physics (with B.I. Halperin), 2003; and Nobel Prize in Physics (with A.A. Abrikosov and V.L. Ginzburg), 2003.

     

  • About the Malmstrom Lectures in Physics

    The Kay Malmstrom Lecture in Physics, part of the Emma K. and Carl R. N. Malstrom Chair in Physics, is an annual symposium on contemporary issues and research in physics. Through this generous gift, Carl R. N. Malmstrom ’36 gives Hamline students access to the outstanding scientific minds of our time. Even after his death in 2010, Carl’s legacy of supporting Hamline students continues to fund collaborative research opportunities, scholarships, and this lecture.
