Fractional Charge in Time-Inversion Invariant Systems
  KTH/Nordita/SU seminar in Theoretical Physics [before December 2013]

Wednesday 02 June 2010
from 11:00 to 12:00
at FA32
Speaker : Roman Jackiw (MIT)
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."
