Shape transitions in exotic Si and S isotopes and tensor-force-driven Jahn-Teller effect
Yutaka Utsuno, Takaharu Otsuka, B. Alex Brown +3
We show how shape transitions in the neutron-rich exotic Si and S isotopes occur in terms of shell-model calculations with a newly constructed Hamiltonian based on V_MU interaction…
Shape coexistence in Lead isotopes in the interacting boson model with Gogny energy density functional
K. Nomura, R. Rodriguez-Guzman, L. M. Robledo +1
We investigate the emergence and evolution of shape coexistence in the neutron-deficient Lead isotopes within the interacting boson model (IBM) plus configuration mixing with micro…
New Generation of the Monte Carlo Shell Model for the K Computer Era
Noritaka Shimizu, Takashi Abe, Yusuke Tsunoda +5
We present a newly enhanced version of the Monte Carlo Shell Model method by incorporating the conjugate gradient method and energy-variance extrapolation. This new method enables…
Variational procedure for nuclear shell-model calculations and energy-variance extrapolation
Noritaka Shimizu, Yutaka Utsuno, Takahiro Mizusaki +3
We discuss a variational calculation for nuclear shell-model calculations and propose a new procedure for the energy-variance extrapolation (EVE) method using a sequence of the app…
Benchmarks of the full configuration interaction, Monte Carlo shell model, and no-core full configuration methods
T. Abe, P. Maris, T. Otsuka +3
We report no-core solutions for properties of light nuclei with three different approaches in order to assess the accuracy and convergence rates of each method. Full configuration…
Efficient computation of Hamiltonian matrix elements between non-orthogonal Slater determinants
Yutaka Utsuno, Noritaka Shimizu, Takaharu Otsuka +1
We present an efficient numerical method for computing Hamiltonian matrix elements between non-orthogonal Slater determinants, focusing on the most time-consuming component of the…
