Friday, November 16
High Energy Theory Seminar - Alfred Shapere - University of Kentucky - "Time Crystals" I consider a class of simple classical dynamical systems which exhibit motion in their lowest-energy states. Their Lagrangians have wrong-sign kinetic terms and their Hamiltonians are multivalued functions of momentum, yet they are amenable to quantization. Their field theoretical generalizations may have applications in condensed matter physics and cosmology. PCTS Seminar Room · 1:30 p.m.– 2:30 p.m.
