A lattice fermion without doubling
A. Hayashi, T. Hashimoto, M. Horibe +1
A free fermion without doubler is formulated on 1+D dimensional discrete Minkowski space-time. The action is not hermitian but causes no harm. In 1+3 dimensional massless case the…

Towards a Canonical Formalism of Field Theory on Discrete Spacetime
Hiroshi Yamamoto, Akihisa Hayashi, Takaaki Hashimoto +1
It is shown that the difficulties in formulating the quantum field theory on discrete spacetime appear already in classical dynamics of one degree of freedom on discrete time. The…
