Odd-Parity Crystalline Electric Field and Multipoles in Icosahedral Quasicrystal and Approximant: Magnetic Toroidal and Electric Dipoles in Ce-Based Systems
Shinji Watanabe, Syunta Furuya, Mitsuaki Kawamura
Quasicrystals (QCs) lack periodic arrangement of atoms but possess unique structural order distinct from periodic crystals and random systems. The electronic property is far from c…
Ground-State Phase Diagram of the Effective Model with Antiferromagnetic Nearest-Neighbor and Ferromagnetic Next-Nearest-Neighbor Interactions in 1/1 Periodic Approximants to Icosahedral Quasicrystals
Shinji Watanabe
By performing complete enumeration of all configurations of magnetic moments, we have determined the ground-state phase diagram of the effective model with antiferromagnetic neares…
GraphDiffMed: Knowledge-Constrained Differential Attention with Pharmacological Graph Priors for Medication Recommendation
Krati Saxena, Tomohiro Shibata
Recommending safe and effective medication combinations from electronic health records (EHRs) is a core clinical AI problem, yet it remains difficult because patient trajectories a…
Analytical foundation for adversarial synchronization control in oscillator networks
Kazuhiro Takemoto
This study provides an analytical foundation for adversarial synchronization control in Kuramoto oscillator networks, where small gradient-based perturbations applied repeatedly to…
-deuteron low-energy -wave phase shifts and momentum correlation functions in Faddeev formulation
M. Kohno, H. Kamada
The low-energy -deuteron scattering is investigated through the solution of Faddeev equations, employing three sets of the currently available representation of the -nucleon…
Non-Collinear and Non-Coplanar Magnetic Orders in 1/1 Periodic Approximant to the Icosahedral Quasicrystal
Shinji Watanabe, Tatsuya Iwasaki
Ground-state properties of rare-earth based 1/1 periodic approximants of icosahedral quasicrystal are clarified theoretically on the basis of an effective model for magnetism takin…
