One-dimensional QCD in thimble regularization
F. Di Renzo, G. Eruzzi
QCD in 0+1 dimensions is numerically solved via thimble regularization. In the context of this toy model, a general formalism is presented for SU(N) theories. The sign problem that…
Simulating thimble regularization of lattice quantum field theories
Francesco Di Renzo, Giovanni Eruzzi
Monte Carlo simulations of lattice quantum field theories on Lefschetz thimbles are non trivial. We discuss a new Monte Carlo algorithm based on the idea of computing contributions…
Thimble regularization at work: from toy models to chiral random matrix theories
Francesco Di Renzo, Giovanni Eruzzi
We apply the Lefschetz thimble formulation of field theories to a couple of different problems. We first address the solution of a complex 0-dimensional phi^4 theory. Although very…
An efficient method to compute the residual phase on a Lefschetz thimble
M. Cristoforetti, F. Di Renzo, G. Eruzzi +4
We propose an efficient method to compute the so-called residual phase that appears when performing Monte Carlo calculations on a Lefschetz thimble. The method is stochastic and it…
