Quantum Monte Carlo methods for nuclear physics
Quantum Monte Carlo methods have proved very valuable to study the structure and reactions of light nuclei and nucleonic matter starting from realistic nuclear interactions and currents. These
Quantum Monte Carlo calculation of the equation of state of neutron matter
We calculated the equation of state of neutron matter at zero temperature by means of the auxiliary field diffusion Monte Carlo (AFDMC) method combined with a fixed-phase approximation. The
Microscopic calculation of the equation of state of nuclear matter and neutron star structure
We present results for neutron star models constructed with a new equation of state for nuclear matter at zero temperature. The ground state is computed using the Auxiliary Field Diffusion Monte
Equation of state of superfluid neutron matter and the calculation of the 1S0 pairing gap.
TLDR
A suppression of the gap with respect to the pure BCS theory is found, but sensibly weaker than in other works that attempt to include polarization effects in an approximate way.
Hyperon puzzle: hints from quantum Monte Carlo calculations.
TLDR
It is found that the three-body hyperon-nucleon interaction plays a fundamental role in the softening of the equation of state and for the consequent reduction of the predicted maximum mass of neutron stars.
Effective field theory for lattice nuclei.
TLDR
It is argued that pionless EFT is the appropriate theory to describe the light nuclei obtained in LQCD simulations carried out at pion masses heavier than the physical pion mass.
Quantum Monte Carlo calculations of neutron matter with nonlocal chiral interactions.
TLDR
This work opens the way to systematic order by order benchmarking of chiral EFT interactions and ab initio prediction of nuclear properties while respecting the symmetries of quantum chromodynamics.
Equation of state of low-density neutron matter, and the 1S0 pairing gap
We report results of the equation of state of neutron matter in the low-density regime, where the Fermi wave vector ranges from $0.4\ensuremath{\leqslant}{k}_{F}\ensuremath{\leqslant}1.0
Quantum Monte Carlo calculations of symmetric nuclear matter.
TLDR
The AFDMC method samples the spin and isospin degrees of freedom allowing for quantum simulations of large nucleonic systems and represents an important step forward towards a quantitative understanding of problems in nuclear structure and astrophysics.
Ab initio computation of the energies of circular quantum dots
We perform coupled-cluster and diffusion Monte Carlo calculations of the energies of circular quantum dots up to 20 electrons. The coupled-cluster calculations include triples corrections and a
