Quantum annealing approach to Ionic Diffusion in Solid
Keishu Utimula, Tom Ichibha, Genki I. Prayogo +3
We have developed a framework for using quantum annealing computation to evaluate a key quantity in ionic diffusion in solids, the correlation factor. Existing methods can only cal…
Ti interstitial flows giving rutile TiO reoxidation process enhanced in (001) surface
Tom Ichibha, Anouar Benali, Kenta Hongo +1
We revisited ab initio evaluations of the energy barriers along the possible diffusion paths of the defects in rutile TiO. By using a method carefully considering the cancellat…
Making the most of data: Quantum Monte Carlo Post-Analysis Revisited
Tom Ichibha, Kenta Hongo, Ryo Maezono +1
In quantum Monte Carlo (QMC) methods, energy estimators are calculated as the statistical average of the Markov chain sampling of energy estimator along with an associated statisti…
Importance of vdW and long-range exchange interactions to DFT-predicted docking energies between plumbagin and cyclodextrins
Tom Ichibha, Ornin Srihakulung, Guo Chao +4
We calculated the docking energies between plumbagin and cyclodextrins, using density functional theory (DFT) with several functionals and some semi-empirical methods. Our DFT resu…
