Validation-Centric AI-Assisted GPU Porting of a 250,000+ Line Legacy Weather Simulation Code
Tetsuya Hoshino, Masaya Kato, Kazuhisa Tsuboki +3
Recent advances in large language models have made CLI-based AI agents a practical tool for accelerating GPU porting of large legacy scientific applications. Such applications, how…
Machine learning technique to find quantum many-body ground states of bosons on a lattice
Hiroki Saito, Masaya Kato
We develop a variational method to obtain many-body ground states of the Bose-Hubbard model using feedforward artificial neural networks. A fully-connected network with a single hi…
Moving obstacle potential in a spin-orbit-coupled Bose-Einstein condensate
Masaya Kato, Xiao-Fei Zhang, Hiroki Saito
We investigate the dynamics around an obstacle potential moving in the plane-wave state of a pseudospin- Bose-Einstein condensate with Rashba spin-orbit coupling. We numerical…
Vortex pairs in a spin-orbit coupled Bose-Einstein condensate
Masaya Kato, Xiao-Fei Zhang, Hiroki Saito
Static and dynamic properties of vortices in a two-component Bose-Einstein condensate with Rashba spin-orbit coupling are investigated. The mass current around a vortex core in the…
Spin-orbit-coupled Bose-Einstein condensates held under toroidal trap
Xiao-Fei Zhang, Masaya Kato, Wei Han +2
We study a quasispin- Bose-Einstein condensate with synthetically generated spin-orbit coupling in a toroidal trap, and show that the system has a rich variety of ground and m…
Twisted spin vortices in a spinor-dipolar Bose-Einstein condensate with Rashba spin-orbit coupling
Masaya Kato, Xiao-Fei Zhang, Daichi Sasaki +1
We consider a spin-1 Bose-Einstein condensate with Rashba spin-orbit coupling and dipole-dipole interaction confined in a cigar-shaped trap. Due to the combined effects of spin-orb…
