Analytic insights on the information content of new observables
Wei-Chia Chen, J. Piekarewicz
Uncertainty quantification has emerged as a rapidly growing field in nuclear science. Theoretical predictions of physical observables often involve extrapolations to regions that a…
Density estimation on small datasets
Wei-Chia Chen, Ammar Tareen, Justin B. Kinney
How might a smooth probability distribution be estimated, with accurately quantified uncertainty, from a limited amount of sampled data? Here we describe a field-theoretic approach…
Nuclear charge radii: Density functional theory meets Bayesian neural networks
Raditya Utama, Wei-Chia Chen, Jorge Piekarewicz
The distribution of electric charge in atomic nuclei is fundamental to our understanding of the complex nuclear dynamics and a quintessential observable to validate nuclear structu…
On the compactness of neutron stars
Wei-Chia Chen, J. Piekarewicz
Recent progress in the determination of both masses and radii of neutron stars are starting to place stringent constraints on the dense matter equation of state. In particular, new…
Searching for isovector signatures in the neutron-rich oxygen and calcium isotopes
Wei-Chia Chen, J. Piekarewicz
We search for potential isovector signatures in the neutron-rich oxygen and calcium isotopes within the framework of a relativistic mean-field theory with an exact treatment of pai…
Building relativistic mean field models for finite nuclei and neutron stars
Wei-Chia Chen, J. Piekarewicz
Background: Theoretical approaches based on density functional theory provide the only tractable method to incorporate the wide range of densities and isospin asymmetries required…
Information and statistics: a new paradigm in theoretical nuclear physics
J. Piekarewicz, Wei-Chia Chen, F. J. Fattoyev
Theoretical predictions of physical observables often involve extrapolations to regions that are poorly constrained by laboratory experiments and astrophysical observations. Withou…
Relativistic mean field plus exact pairing approach to open shell nuclei
Wei-Chia Chen, J. Piekarewicz, A. Volya
Background: Pairing correlations play a critical role in determining numerous properties of open-shell nuclei. Traditionally, they are included in a mean-field description of atomi…
Giant monopole energies from a constrained relativistic mean-field approach
Wei-Chia Chen, J. Piekarewicz, M. Centelles
Background: Average energies of nuclear collective modes may be efficiently and accurately computed using a non-relativistic constrained approach without reliance on a random phase…
