The sign problem and the Lefschetz thimble
Marco Cristoforetti, Francesco Di Renzo, Luigi Scorzato
Recently, we have proposed a novel approach (arxiv:1205.3996) to deal with the sign problem that hinders Monte Carlo simulations of many quantum field theories (QFTs). The approach…
Quark flavour effects on gluon and ghost propagators
A. Ayala, A. Bashir, D. Binosi +2
We compute the full non-perturbative ghost and gluon two-point Green functions by using gauge field configurations with $\nf=2$ and $\nf=2+1+1$ twisted-mass quark flavours. We use…
High density QCD on a Lefschetz thimble?
AuroraScience Collaboration, Marco Cristoforetti, Francesco Di Renzo +1
It is sometimes speculated that the sign problem that afflicts many quantum field theories might be reduced or even eliminated by choosing an alternative domain of integration with…
