Constraining the nuclear energy density functional with quantum Monte Carlo calculations
Alessandro Roggero, Abhishek Mukherjee, Francesco Pederiva
We study the problem of an impurity in fully polarized (spin-up) low density neutron matter with the help of an accurate quantum Monte Carlo method in conjunction with a realistic…
Lefschetz thimble Monte Carlo for many body theories: application to the repulsive Hubbard model away from half filling
Abhishek Mukherjee, Marco Cristoforetti
Recently, a new method, based on stochastic integration on the surfaces of steepest descent of the action, was introduced to tackle the sign problem in quantum field theories. We s…
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 Monte Carlo calculations of neutron matter with non-local chiral interactions
Alessandro Roggero, Abhishek Mukherjee, Francesco Pederiva
We present fully non-perturbative quantum Monte Carlo calculations with non-local chiral effective field theory (EFT) interactions for the ground state properties of neutron matter…
Recent Advances in the Microscopic Calculations of Level Densities by the Shell Model Monte Carlo Method
Y. Alhassid, M. Bonett-Matiz, S. Liu +2
The shell model Monte Carlo (SMMC) method enables calculations in model spaces that are many orders of magnitude larger than those that can be treated by conventional methods, and…
