Ab Initio and Ab Exitu No-Core Shell Model


Book Description

We outline two complementary approaches based on the no core shell model (NCSM) and present recent results. In the ab initio approach, nuclear properties are evaluated with two-nucleon (NN) and three-nucleon interactions (TNI) derived within effective field theory (EFT) based on chiral perturbation theory (ChPT). Fitting two available parameters of the TNI generates good descriptions of light nuclei. In a second effort, an ab exitu approach, results are obtained with a realistic NN interaction derived by inverse scattering theory with off-shell properties tuned to fit light nuclei. Both approaches produce good results for observables sensitive to spin-orbit properties.










Changing Facets of Nuclear Structure


Book Description

This volume provides a comprehensive survey by international experts of recent developments in the field of nuclear structure. Both experimental and theoretical issues are covered. On the experimental side, the latest research and the envisaged developments in the most important laboratories, where radioactive ion beams are available, are reviewed in detail. On the theoretical side, the various approaches to a fundamental theory of nuclear structure starting from the nucleon-nucleon interaction are discussed, going from few-body systems, where ?ab initio? calculations are possible, to complex nuclei, where the shell model plays a key role. Results of current experimental and theoretical studies on exotic nuclei are also presented.










Emergent Phenomena In Atomic Nuclei From Large-scale Modeling: A Symmetry-guided Perspective


Book Description

This book is a unique collection of reviews that share a common topic, emergent phenomena in atomic nuclei, while revealing the multifaceted nature of the subject, from quarks to heavy nuclei. It tells an amazing story of a decades-long journey of trials and successes, up to present days, with the aim to understand the vast array of experimental data and the fundamentals of strongly interacting fermions. The emphasis is on discovering emergent orderly patterns amidst the overarching complexity of many-particle quantum-mechanical systems. Recent findings are discussed within an interesting framework: a combination of nuclear theory and experiment, of group theory and computational science, and of pivotal models of astonishing simplicity and state-of-the-art models empowered by supercomputers.A special theme resonates throughout the book: the important role of symmetries, exact and approximate, in exposing emergent features and guiding large-scale nuclear modeling. World-renowned experts offer their unique perspective on symmetries in the world of quarks and gluons, and that of protons and neutrons — from chiral symmetry, through spin-isospin and quasi-spin symmetries, to symplectic symmetry, — as well as on the emergent nature of nuclear collectivity, clustering, and pairing, viewed from spectroscopy, microscopic considerations, and first principles. The book provides an excellent foundation that allows researchers and graduate students in physics and applied mathematics to review the current status of the subject, and to further explore the research literature through exhaustive sets of references that also point to studies underpinned by similar techniques in condensed matter and atomic physics along with quantum information.

Book Description

This volume provides a comprehensive survey by international experts of recent developments in the field of nuclear structure. Both experimental and theoretical issues are covered. On the experimental side, the latest research and the envisaged developments in the most important laboratories, where radioactive ion beams are available, are reviewed in detail. On the theoretical side, the various approaches to a fundamental theory of nuclear structure starting from the nucleon-nucleon interaction are discussed, going from few-body systems, where “ab initio” calculations are possible, to complex nuclei, where the shell model plays a key role. Results of current experimental and theoretical studies on exotic nuclei are also presented.
