Four-dimensional domain decomposition for the factorization of the fermion determinant
Matteo Saccardi, Leonardo Giusti
The non-local dependence of the fermion determinant on the gauge field limits our ability of simulating Quantum Chromodynamics on the lattice. Here we present a factorization of th…

Four-dimensional factorization of the fermion determinant in lattice QCD
Leonardo Giusti, Matteo Saccardi
In the last few years it has been proposed a one-dimensional factorization of the fermion determinant in lattice QCD with Wilson-type fermions that leads to a block-local action of…
