  • Dr. Dave Morrison, KITP & Duke University, How Much Mathematics Does a Theoretical Physicist Need to Know?
    the physics of motion Most of the mathematics which is part of the standard physics curriculum today is from the 19th century or earlier Is 19th century mathematics adequate for 21st century physics I believe that it is not and will give examples drawn from condensed matter as well as high energy theory Begin QuickTime of the whole talk high bandwidth Or right click to download the movie Or right

  • Dr. Alexei Kitaev, KITP & Microsoft, Anyons in an Exactly Solved Model and Beyond
    The other phase is gapless but acquires a gap in the presence of magnetic field in which case excitations are non Abelian anyons I will also discuss a general theory of free fermions with a gapped spectrum characterized by a spectral Chern number nu The Abelian and non Abelian phases of the original model correspond to nu 0 and nu pm 1 respectively The anyonic properties of excitation depend on

  • Dr. Albert Libchaber, Rockefeller, Some Physical Aspects of the Origin of Life and of Artificial Cells
    up Non equilibrium thermodynamics can thus help to solve some nagging problems of critical concentration and sequence selection in a prebiotic soup We show that a vesicle bioreactor can function for many days in an homeostatis state producing proteins This is a first necessary step to artificial cells The next step will be vesicle replication Begin WebCam and audio for the whole talk high bandwidth or medium bandwidth Or begin

  • Dr. Gary Horowitz, UCSB, Spacetime in String Theory
    relativity I will provide an overview of the nature of spacetime emerging from string theory This is radically different from relativity At a perturbative level the spacetime metric appears as coupling constants in a two dimensional quantum field theory Nonperturbatively with certain boundary conditions spacetime is not fundamental but must be reconstructed from a holographic dual theory I will conclude with some recent ideas about the big bang arising from
