Fermion doubling problem

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.
