Energy density functional methods for atomic nuclei Energy density functional (EDF) approaches have become over the past twenty years a powerful framework to study the structure and reactions of atomic nuclei. This book gives an updated presentation of non relativistic and covariant energy functionals single and multi reference methods and techniques to describe small and large amplitude collective motion or nuclei at high excitation energy. Edited by an expert in energy density functional theory Dr Nicolas Schunck alongside several experts within the field this book provides a comprehensive and informative exploration of EDF methods. Detailed derivations practical approaches examples and figures are used throughout the book to give a coherent narrative of topics that have hitherto rarely been covered together.
