Electron fractionalization for two-dimensional Dirac fermions
Claudio Chamon, Chang-Yu Hou, Roman Jackiw +3
Fermion-number fractionalization without breaking of time-reversal symmetry was recently demonstrated for a field theory in -dimensional space and time that describes the co…

Irrational vs. rational charge and statistics in two-dimensional quantum systems
Claudio Chamon, Chang-Yu Hou, Roman Jackiw +3
We show that quasiparticle excitations with irrational charge and irrational exchange statistics exist in tight-biding systems described, in the continuum approximation, by the Dir…
