Robust ab initio predictions for dimensionless ratios of E2 and radius observables. I. Electric quadrupole moments and deformation
Mark A. Caprio, Pieter Maris, Patrick J. Fasano
Converged results for E2 observables are notoriously challenging to obtain in ab initio no-core configuration interaction (NCCI) approaches. Matrix elements of the E2 operator are…
Accelerating Eigenvalue Computation for Nuclear Structure Calculations via Perturbative Corrections
Dong Min Roh, Esmond Ng, Chao Yang +3
We present a new method for computing the lowest few eigenvalues and the corresponding eigenvectors of a nuclear many-body Hamiltonian represented in a truncated configuration inte…
Direct ab initio calculation of the He nuclear electric dipole polarizability
Peng Yin, Andrey M. Shirokov, Pieter Maris +5
The calculation of nuclear electromagnetic sum rules by directly diagonalizing the nuclear Hamiltonian in a large basis is numerically challenging and has not been performed for $A…
Intruder band mixing in an ab initio description of 12Be
Anna E. McCoy, Mark A. Caprio, Pieter Maris +1
The spectrum of 12Be exhibits exotic features, e.g., an intruder ground state and shape coexistence, normally associated with the breakdown of a shell closure. While previous pheno…
