Domain decomposition and multilevel integration for fermions
Marco Cè, Leonardo Giusti, Stefan Schaefer
The numerical computation of many hadronic correlation functions is exceedingly difficult due to the exponentially decreasing signal-to-noise ratio with the distance between source…
The large limit of the topological susceptibility of Yang-Mills gauge theory
Marco Cè, Miguel García Vera, Leonardo Giusti +1
We present a precise computation of the topological susceptibility of SU Yang-Mills theory in the large limit. The computation is done on the lattice, u…
A local factorization of the fermion determinant in lattice QCD
Marco Cè, Leonardo Giusti, Stefan Schaefer
We introduce a factorization of the fermion determinant in lattice QCD with Wilson-type fermions that leads to a bosonic action which is local in the block fields. The interaction…
The topological susceptibility in the large-N limit of SU(N) Yang-Mills theory
Marco Cè, Miguel García Vera, Leonardo Giusti +1
We compute the topological susceptibility of the SU(N) Yang-Mills theory in the large-N limit with a percent level accuracy. This is achieved by measuring the gradient-flow definit…
Domain decomposition, multi-level integration and exponential noise reduction in lattice QCD
Marco Cè, Leonardo Giusti, Stefan Schaefer
We explore the possibility of computing fermionic correlators on the lattice by combining a domain decomposition with a multi-level integration scheme. The quark propagator is expa…
