From credible shell model interactions to neutron-capture uncertainties
Oliver Gorton, Konstantinos Kravvaris
Nuclear structure theory can provide nuclear astrophysics and nuclear technologies with bound state properties and transition rates. When describing nuclear reactions, the list can…
Radiative strength functions from the energy-localized Brink-Axel hypothesis
Oliver C. Gorton, Konstantinos Kravvaris, Jutta E. Escher +1
Radiative strength functions (RSFs) model the bulk electromagnetic response of highly-excited nuclei and are critical inputs for statistical reaction codes. In this paper, we prese…
Towards shell model interactions with credible uncertainties
Oliver C. Gorton, Konstantinos Kravvaris
Background: The nuclear shell model is a powerful framework for predicting nuclear structure observables, but relies on interaction matrix elements fit to experimental data as its…
Solar fusion III: New data and theory for hydrogen-burning stars
B. Acharya, M. Aliotta, A. B. Balantekin +47
In stars that lie on the main sequence in the Hertzsprung-Russel diagram, like our sun, hydrogen is fused to helium in a number of nuclear reaction chains and series, such as the p…
Tunable-fidelity wave functions for the \textit{ab initio} description of scattering and reactions
Konstantinos Kravvaris, Sofia Quaglioni, Petr Navratil
The no-core shell model (NCSM) is an \textit{ab initio} method that solves the nuclear many-body problem by expanding the many-particle wave function into a (typically) harmonic os…
Impact of the Li asymptotic normalization constant onto -induced reactions of astrophysical interest
Chloë Hebborn, Melina L. Avila, Konstantinos Kravvaris +2
Indirect methods have become the predominant approach in experimental nuclear astrophysics for studying several low-energy nuclear reactions occurring in stars, as direct measureme…
Perspectives on few-body cluster structures in exotic nuclei
D. Bazin, K. Becker, F. Bonaiti +16
It is a fascinating phenomenon in nuclear physics that states with a pronounced few-body structure can emerge from the complex dynamics of many nucleons. Such halo or cluster state…
Quantifying uncertainties due to irreducible three-body forces in deuteron-nucleus reactions
Linda Hlophe, Konstantinos Kravvaris, Sofia Quaglioni
\noindent{\bf Background:} Deuteron-induced nuclear reactions are an essential tool for probing the structure of nuclei as well as astrophysical information such as cross s…
Ab initio prediction of the big bang radiative capture
Chloë Hebborn, Guillaume Hupin, Konstantinos Kravvaris +3
The rate at which helium (He) and deuterium () fuse together to produce lithium-6 (Li) and a ray, HeLi, is a critical puzzle piece in resolving the roug…
Ab initio informed evaluation of the radiative capture of protons on Be
Konstantinos Kravvaris, Petr Navrátil, Sofia Quaglioni +2
The radiative capture of protons by Be, which is the source of B that -decays emitting the majority of solar neutrinos measured on earth, has not yet been measured at as…
Ab initio framework for nuclear scattering and reactions induced by light projectiles
Konstantinos Kravvaris, Sofia Quaglioni, Guillaume Hupin +1
A quantitative and predictive microscopic theoretical framework that can describe reactions induced by particles (He nuclei) and heavier projectiles is currently lacking. S…
Quantifying uncertainties in neutron-alpha scattering with chiral nucleon-nucleon and three-nucleon forces
Konstantinos Kravvaris, Kevin R. Quinlan, Sofia Quaglioni +2
Background: Modern ab initio theory combined with high-quality nucleon-nucleon (NN) and three-nucleon (3N) interactions from chiral effective field theory (EFT) can provide a predi…
Optimal Control for the Quantum Simulation of Nuclear Dynamics
Eric T. Holland, Kyle A. Wendt, Konstantinos Kravvaris +5
We propose a method for enacting the unitary time propagation of two interacting neutrons at leading order of chiral effective field theory by efficiently encoding the nuclear dyna…
