Parametric Neural Quantum States for Nuclear Physics
Yukari Yamauchi, Ryan Curry, Garrett B. King +3
We introduce a new approach, based on neural quantum states (NQSs), to rapidly compute nuclear observables when couplings in nuclear Hamiltonians are varied. A single interaction-d…
An Agentic Orchestration of Atomistic Simulations
Rahul Somasundaram, Adela Habib, Khanh Dang +12
Atomistic simulations are central to materials design, but their execution involves complex, multi-step workflows that require significant human expertise. Here, we present an agen…
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…

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…
URSA: The Universal Research and Scientific Agent
Michael Grosskopf, Nathan Debardeleben, Russell Bent +10
Large language models (LLMs) have moved far beyond their initial form as simple chatbots, now carrying out complex reasoning, planning, writing, coding, and research tasks. These s…
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

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.…
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…
Can Neutron Star Tidal Effects Obscure Deviations from General Relativity?
Stephanie M. Brown, Badri Krishnan, Rahul Somasundaram +1
One of the main goals of gravitational-wave astrophysics is to study gravity in the strong-field regime and constrain deviations from general relativity (GR). Any such deviation af…
Inferring three-nucleon couplings from multi-messenger neutron-star observations
Rahul Somasundaram, Isak Svensson, Soumi De +5
Understanding the interactions between nucleons in dense matter is an important challenge in theoretical physics. Effective field theories have emerged as the dominant approach to…
Perturbative treatment of nonlocal chiral interactions in auxiliary-field diffusion Monte Carlo calculations
Ryan Curry, Rahul Somasundaram, Stefano Gandolfi +2
Nuclear many-body systems, ranging from nuclei to neutron stars, are some of the most interesting physical phenomena in our universe, and Quantum Monte Carlo (QMC) approaches are a…
The impact of dark matter on tidal signatures in neutron star mergers with Einstein Telescope
Hauke Koehn, Edoardo Giangrandi, Nina Kunert +3
If dark matter (DM) accumulates inside neutron stars (NS), it changes their internal structure and causes a shift of the tidal deformability from the value predicted by the dense-m…
