Constraining Hamiltonians from chiral effective field theory with neutron-star data
Cassandra L. Armstrong, Brendan T. Reed, Tate Plohr +4
Multi-messenger observations of neutron stars (NSs) and their mergers have placed strong constraints on the dense-matter equation of state (EOS). The EOS, in turn, depends on micro…
Quantum Monte Carlo Calculations of Light Nuclei with Fully Propagated Theoretical Uncertainties
Ryan Curry, Kai Hebeler, Stefano Gandolfi +4
We report on the first quantum Monte Carlo calculations of helium isotopes with fully propagated theoretical uncertainties from the interaction to the many-body observables. To ach…
The nucleardatapy toolkit for simple access to experimental nuclear data, astrophysical observations, and theoretical predictions
Jérôme Margueron, Christian Drischler, Mariana Dutra +10
Systematic comparisons across theoretical predictions for the properties of dense matter, nuclear physics data, and astrophysical observations (also called meta-analyses) are perfo…
Direct Inference of Nuclear Equation-of-State Parameters from Gravitational-Wave Observations
Brendan T. Reed, Cassandra L. Armstrong, Rahul Somasundaram +4
The observation of neutron star mergers with gravitational waves (GWs) has provided a new method to constrain the dense-matter equation of state (EOS) and to better understand its…
Leveraging differentiable programming in the inverse problem of neutron stars
Thibeau Wouters, Peter T. H. Pang, Hauke Koehn +5
Neutron stars (NSs) probe the high-density regime of the nuclear equation of state (EOS). However, inferring the EOS from observations of NSs is a computationally challenging task.…
Interface modes in inspiralling neutron stars: A gravitational-wave probe of first-order phase transitions
A. R. Counsell, F. Gittins, N. Andersson +1
At the extreme densities in neutron stars, a phase transition to deconfined quark matter is anticipated. Yet masses, radii and tidal deformabilities offer only indirect measures of…
Emulators for Scarce and Noisy Data: Application to Auxiliary-Field Diffusion Monte Carlo for Neutron Matter
Cassandra L. Armstrong, Pablo Giuliani, Kyle Godbey +2
Understanding the equation of state (EOS) of pure neutron matter is necessary for interpreting multimessenger observations of neutron stars. Reliable data analyses of these observa…
Neutron matter from local chiral effective field theory interactions at large cutoffs
I. Tews, R. Somasundaram, D. Lonardoni +6
Neutron matter is an important many-body system that provides valuable constraints for the equation of state (EOS) of neutron stars. Neutron-matter calculations employing chiral ef…
Towards accelerated nuclear-physics parameter estimation from binary neutron star mergers: Emulators for the Tolman-Oppenheimer-Volkoff equations
Brendan T. Reed, Rahul Somasundaram, Soumi De +5
Gravitational-wave observations of binary neutron-star (BNS) mergers have the potential to revolutionize our understanding of the nuclear equation of state (EOS) and the fundamenta…
Emulators for scarce and noisy data: application to auxiliary field diffusion Monte Carlo for the deuteron
Rahul Somasundaram, Cassandra L. Armstrong, Pablo Giuliani +3
The validation, verification, and uncertainty quantification of computationally expensive theoretical models of quantum many-body systems require the construction of fast and accur…
Maximally local two-nucleon interactions at NLO in -less chiral effective field theory
Rahul Somasundaram, Joel E. Lynn, Lukas Huth +2
We present new maximally local two-nucleon interactions derived in -less chiral effective field theory up to next-to-next-to-next-to-leading order (NLO), which include all c…
Reproducing the results for NICER observation of PSR J0030+0451
Chaitanya Afle, Patrick R. Miles, Silvina Caino-Lores +6
NASA's Neutron Star Interior Composition Explorer (NICER) observed X-ray emission from the pulsar PSR J0030+0451 in 2018. Riley et al. reported Bayesian parameter measurements of t…
Constraints on the nuclear symmetry energy from asymmetric-matter calculations with chiral NN and 3N interactions
R. Somasundaram, C. Drischler, I. Tews +1
The nuclear symmetry energy is a key quantity in nuclear (astro)physics. It describes the isospin dependence of the nuclear equation of state (EOS), which is commonly assumed to be…

From the microscopic to the macroscopic world: from nucleons to neutron stars
S. Gandolfi, J. Lippuner, A. W. Steiner +3
Recent observations of neutron-star properties, in particular the recent detection of gravitational waves emitted from binary neutron stars, GW 170817, open the way to put strong c…
