From Polyhedra to Crystals: A Graph-Theoretic Framework for Crystal Structure Generation
Tomoyasu Yokoyama, Kazuhide Ichikawa, Hisashi Naito
Crystal structures can be viewed as assemblies of space-filling polyhedra, which play a critical role in determining material properties such as ionic conductivity and dielectric c…
Quantum computation of a quasiparticle band structure with the quantum-selected configuration interaction
Takahiro Ohgoe, Hokuto Iwakiri, Kazuhide Ichikawa +2
Quasiparticle band structures are fundamental for understanding strongly correlated electron systems. While solving these structures accurately on classical computers is challengin…
Crystal Structure Generation Based on Polyhedra using Dual Periodic Graphs
Tomoyasu Yokoyama, Kazuhide Ichikawa, Hisashi Naito
Crystal structure design is important for the discovery of new highly functional materials because crystal structure strongly influences material properties. Crystal structures are…
Representation Synthesis by Probabilistic Many-Valued Logic Operation in Self-Supervised Learning
Hiroki Nakamura, Masashi Okada, Tadahiro Taniguchi
In this paper, we propose a new self-supervised learning (SSL) method for representations that enable logic operations. Representation learning has been applied to various tasks, s…
Demonstrating Quantum Computation for Quasiparticle Band Structures
Takahiro Ohgoe, Hokuto Iwakiri, Masaya Kohda +4
Understanding and predicting the properties of solid-state materials from first-principles has been a great challenge for decades. Owing to the recent advances in quantum technolog…
Accelerating Optimal Elemental Configuration Search in Crystal using Ising Machine
Kazuhide Ichikawa, Satoru Ohuchi, Koki Ueno +1
This research demonstrates that Ising machines can effectively solve optimal elemental configuration searches in crystals, with Au-Cu alloys serving as an example. The energy funct…
