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…
First Principles Calculations of Superconducting Critical Temperature of ThCrSi-Type Structure
Gewinner Senderanto Sinaga, Keishu Utimula, Kousuke Nakano +2
High critical temperature (T) superconductor has a great potential in many industrial applications. However, discovering a compound having high T is still remaining a big c…
Stochastic estimations of a total number of classes for the clusterings with too enormous samples to be accommodate into a clustering engine
Keishu Utimula, Genki I. Prayogo, Kousuke Nakano +2
We considered the problem how to handle the exploding number of possibilities to be sorted into irreducible classes by using a clustering tool when its input capacity cannot accomm…
Speeding up the ab initio diffusion Monte Carlo by a smart lattice regularization
Kousuke Nakano, Ryo Maezono, Sandro Sorella
One of the most significant drawbacks of the all-electron ab initio diffusion Monte Carlo (DMC) is that its computational cost drastically increases with the atomic number (), w…
All-electron quantum Monte Carlo with Jastrow single determinant Ansatz: application to the sodium dimer
Kousuke Nakano, Ryo Maezono, Sandro Sorella
In this work, we report potential energy surfaces (PESs) of the sodium dimer calculated by variational (VMC) and lattice regularized diffusion Monte Carlo (LRDMC). The VMC calculat…
