WebOct 11, 2024 · In particular, there is the fermion doubling problem, namely that it is impossible to put a single chiral non-interacting fermion on the lattice. Therefore allow me to discuss your question in the simplest case: a scalar field in ( 0 + 1) dimensions. Our variable is a field ϕ: Z → R, x ↦ ϕ ( x). For simplicity i will set the lattice constant to 1. WebAug 1, 1994 · Fermion doubling and a natural solution of the strong [ital CP] problem Full Record Research Abstract We suggest the fermion doubling for all quarks and leptons. It is a generalization of the neutrino doubling of the seesaw mechanism. The new quarks and leptons are SU (2) singlets and carry the electromagnetic charges of their lighter …

The problem of fermion doubling occurs in numerical formulations of the Dirac equation on lattices when the operators of the first … WebNov 4, 2010 · By exploiting laser-assisted tunneling, we find an analogue of the so-called naive Dirac fermions, and thus provide a realization of the fermion doubling problem. Moreover, we show how to implement Wilson fermions, and discuss how their mass can be inverted by tuning the laser intensities.
