| Abstract: | After reviewing the theory of finite dimensional semi-simple Lie algebras and then Kac-Moody algebras, I will present the evidence for an E11 symmetry of an underlying theory of strings and branes. |

| Fractional Charges and Zero Modes & Majorana Fermions in Superconductors |
| Speaker: | Roman Jackiw (Massachusetts Institute of Technology) |
| Abstract: | The essence of quantum mechanics is that dynamical entities, like energy or angular momentum, which can take arbitrary values within classical physics, become quantized within quantum physics. I shall describe an inverse phenomenon: Classical entities like particle number or charge possess an intrinsic integrality; but they can acquire fractional values upon quantization. I shall describe how this phenomenon is realized through zero modes of a Dirac equation, and how the effect manifests itself in condensed matter materials. |
