AI-Assisted GPU optimization of the Stochastic Variational Method for Few-Body Boson System
Noritaka Shimizu, Shigeyoshi Aoyama, Yusuke Tsunoda +1
The stochastic variational method (SVM) is one of the most powerful methods to solve quantum few-body systems precisely in various fields, such as nuclear and atomic physics. To th…
Bayesian Variational Method for Precision Few-Body Calculations
Shigeyoshi Aoyama
Many variational descriptions of quantum many-body systems rest on an expansion over basis functions, and their practical limit is often set by the number of basis functions requir…
A microscopic cluster model study of He+ scatterings
K. Arai, S. Aoyama, Y. Suzuki
We calculate He+ scattering phase shifts in two different microscopic cluster models, Model T and Model C, in order to show the effects of tensor force as well as -wave c…
Three-body Coulomb breakup of 11Li in the complex scaling method
T. Myo, S. Aoyama, K. Kato +1
Coulomb breakup strengths of 11Li into a three-body 9Li+n+n system are studied in the complex scaling method. We decompose the transition strengths into the contributions from thre…
Extended 9Li+n+n three-body model of 11Li with the pairing correlation in 9Li
Takayuki Myo, Shigeyoshi Aoyama, Kiyoshi Kato +1
We discuss the binding mechanism of 11Li based on an extended three-body model of Li+n+n. In the model, we take into account the pairing correlation of p-shell neutrons in 9Li, in…
Study for the s-wave in ^{10}Li with analysis of cross-sections
Hiroshi Masui, Shigeyoshi Aoyama, Kiyoshi Katō +1
We study the effect of s-wave cross-sections in He+ and Li+ elastic scattering reactions by using the Jost function method (JFM). In He (He+), the…
