Discrete quantum gravity: continuum limit and the problem of state doubling
arXiv:hep-th/0606102
Abstract
It is shown that in the theory of discrete quantum gravity defined on the irregular "breathing" lattice, if the macroscopic continuum phase is realized, the phenomenon of state doubling (even if it exists formally at kinematic level) actually is absent at experimentally accessible energies.
