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…
Metropolis Monte Carlo on the Lefschetz thimble: application to a one-plaquette model
Abhishek Mukherjee, Marco Cristoforetti, Luigi Scorzato
We propose a new algorithm based on the Metropolis sampling method to perform Monte Carlo integration for path integrals in the recently proposed formulation of quantum field theor…
Quantum Monte Carlo with Coupled-Cluster wave functions
Alessandro Roggero, Abhishek Mukherjee, Francesco Pederiva
We introduce a novel many body method which combines two powerful many body techniques, viz., quantum Monte Carlo and coupled cluster theory. Coupled cluster wave functions are int…
Level densities of nickel isotopes: microscopic theory versus experiment
M. Bonett-Matiz, Abhishek Mukherjee, Y. Alhassid
We apply a spin-projection method to calculate microscopically the level densities of a family of nickel isotopes Ni using the shell model Monte Carlo approach in the com…
Configuration-interaction Monte Carlo method and its application to the trapped unitary Fermi gas
Abhishek Mukherjee, Y. Alhassid
We develop a quantum Monte Carlo method to estimate the ground-state energy of a fermionic many-particle system in the configuration-interaction shell model approach. The fermionic…
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…
