A development of an accelerator board dedicated for multi-precision arithmetic operations and its application to Feynman loop integrals II
H Daisaka, N Nakasato, T Ishikawa +2
Evaluation of a wide variety of Feynman diagrams with multi-loop integrals and physical parameters and its comparison with high energy experiments are expected to investigate new p…
Hierarchical Tree Algorithm for Collisional N-body Simulations on GRAPE
Toshiyuki Fukushige, Atsushi Kawai
We present an implementation of the hierarchical tree algorithm on the individual timestep algorithm (the Hermite scheme) for collisional -body simulations, running on GRAPE-9 s…
A development of an accelerator board dedicated for multi-precision arithmetic operations and its application to Feynman loop integrals
Shinji Motoki, Hiroshi Daisaka, Naohito Nakasato +5
Higher order corrections in perturbative quantum field theory are required for precise theoretical analysis to investigate new physics beyond the Standard Model. This indicates tha…
Effects of Hardness of Primordial Binaries on Evolution of Star Clusters
Ataru Tanikawa, Toshiyuki Fukushige
We investigate effects of hardness of primordial binaries on whole evolution of star clusters by means of N-body simulations. Using newly developed code, GORILLA, we simulated elev…
Mass-Loss Timescale of Star Clusters in an External Tidal Field. II. Effect of Mass Profile of Parent Galaxy
Ataru Tanikawa, Toshiyuki Fukushige
We investigate the long-term dynamical evolution of star clusters in a steady tidal field produced by its parent galaxy. In this paper, we focus on the influence of mass profile of…
GreeM : Massively Parallel TreePM Code for Large Cosmological N-body Simulations
Tomoaki Ishiyama, Toshiyuki Fukushige, Junichiro Makino
In this paper, we describe the implementation and performance of GreeM, a massively parallel TreePM code for large-scale cosmological N-body simulations. GreeM uses a recursive mul…
