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…
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…
Tensor-force-driven Jahn-Teller effect and shape transitions in exotic Si isotopes
Yutaka Utsuno, Takaharu Otsuka, B. Alex Brown +3
We show how the shape evolution of the neutron-rich exotic Si and S isotopes can be understood as a Jahn-Teller effect that comes in part from the tensor-driven evolution of single…
