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…
Quantum field theories on the Lefschetz thimble
M. Cristoforetti, F. Di Renzo, A. Mukherjee +1
In these proceedings, we summarize the Lefschetz thimble approach to the sign problem of Quantum Field Theories. In particular, we review its motivations, and we summarize the resu…
Monte Carlo simulations on the Lefschetz thimble: taming the sign problem
Marco Cristoforetti, Francesco Di Renzo, Abhishek Mukherjee +1
We present the first practical Monte Carlo calculations of the recently proposed Lefschetz thimble formulation of quantum field theories. Our results provide strong evidence that t…
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…
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…
