Interplay between Nuclear Shell Structure and Pairing around Doubly Magic Sn
Rane Simpson, Georgios Palkanoglou, Ellen Brisley +20
Shell structure in finite quantum systems gives rise to sudden changes in observable properties, while pairing correlations often compete against such discontinuities. The region n…
Six textbook mistakes in quantum field theory
Alexandros Gezerlis
This article discusses incorrect statements appearing in textbooks on quantum field theory (QFT); some of these mistakes also appear in the research literature. The focus is not on…
Conformal prediction for uncertainties in the neutron star equation of state
Habib Yousefi Dezdarani, Ryan Curry, Cassandra L. Armstrong +1
We study uncertainties in the equation of state of neutron stars using conformal prediction as a distribution-free and model-agnostic method that provides coverage guarantees. In p…
Ab initio study of the neutron and Fermi polarons on the lattice
Ryan Curry, Jasmine Kozar, Alexandros Gezerlis
We have used the auxiliary-field quantum Monte Carlo (AFQMC) many-body approach on the lattice to study the equation of state for a fermionic impurity interacting with a background…
Evidence for Multimodal Superfluidity of Neutrons
Yuan-Zhuo Ma, Georgios Palkanoglou, Joseph Carlson +7
We present theoretical and experimental evidence for a new phase of matter in neutron-rich systems that we call multimodal superfluidity. Using ab initio lattice calculations, we 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…
