The 1S0 Pairing Gap in Neutron Matter
Condensed Matter, 2022 We report ab initio calculations of the S wave pairing gap in neutron matter calculated using realistic nuclear Hamiltonians that include two- and three-body interactions.

Low-Density Neutron Matter and the Unitary Limit
Frontiers in Physics, 2021 We review the properties of neutron matter in the low-density regime. In particular, we revise its ground state energy and the superfluid neutron pairing gap and analyze their evolution from the weak to the strong coupling regime. The calculations of the

Monte Carlo simulation of the resolution volume for the SEQUOIA spectrometer
EPJ Web of Conferences, 2015 Monte Carlo ray tracing simulations, of direct geometry spectrometers, have been particularly useful in instrument design and characterization. However, these tools can also be useful for experiment planning and analysis.

Functional renormalization group approach to neutron matter
Physics Letters B, 2014 The chiral nucleon-meson model, previously applied to systems with equal number of neutrons and protons, is extended to asymmetric nuclear matter. Fluctuations are included in the framework of the functional renormalization group.

Quark-hybrid matter in the cores of massive neutron stars [PDF]
, 2012 Using a nonlocal extension of the SU(3) Nambu-Jona Lasinio model, which reproduces several of the key features of Quantum Chromodynamics, we show that mixed phases of deconfined quarks and confined hadrons (quark-hybrid matter) may exist in the cores of ...

Neutron matter - Quark matter phase transition and Quark star
, 1993 We consider the neutron matter quark matter phase transition along with possible existence of hybrid quark stars. The equation of state for neutron matter is obtained using a nonperturbative method with pion dressing of the neutron matter and an analysis

Dark Matter, Neutron Stars, and Strange Quark Matter [PDF]
Physical Review Letters, 2010 We show that self-annihilating neutralino WIMP dark matter accreted onto neutron stars may provide a mechanism to seed compact objects with long-lived lumps of strange quark matter, or strangelets, for WIMP masses above a few GeV. This effect may trigger a conversion of most of the star into a strange star.

Multi-messenger observations of neutron rich matter
, 2011 Neutron rich matter is central to many fundamental questions in nuclear physics and astrophysics. Moreover, this material is being studied with an extraordinary variety of new tools such as the Facility for Rare Isotope Beams (FRIB) and the Laser ...

Neutron matter on the lattice with pionless effective field theory
, 2004 We study neutron matter by combining pionless effective field theory with non-perturbative lattice methods. The neutron contact interaction is determined by zero temperature scattering data. We simulate neutron matter on the lattice at temperatures 4 and
