Particle-number restoration within the energy density functional formalism
TL;DR: In this article, a detailed analysis of the origin of spurious divergences and finite steps that have been recently identified in particle-number-restoration calculations within the nuclear energy density functional framework is given.

Particle-number restoration within the energy density functional formalism: Nonviability of terms depending on noninteger powers of the density matrices
TL;DR: In this article, the authors address the viability of non-integer powers of the density matrices in the nuclear energy density functional and conclude that noninteger powers are not viable and should be avoided in the first place when constructing the energy density functionals that are eventually meant to be used in multi-reference calculations.

TL;DR: In this paper, the authors discuss the existence of pathological behaviors in particle-number restoration calculations performed within the nuclear energy density functional framework and conclude that non-integer powers of the density matrices are not viable and should be avoided in the first place when constructing nuclear EDF functionals that are eventually used in multi-reference calculations.

TL;DR: The rotational band structure of Lr-255 has been investigated using advanced in-beam gamma-ray spectroscopic techniques as mentioned in this paper, which is the largest nucleus to date to be studied in this manner.

TL;DR: In this article, a set of matrix elements, coupling the low-lying states in these isotopes, is extracted, and three model descriptions are used to compare to the data, including the beyond-mean field model, the interacting boson model, and the general Bohr Hamiltonian model.
