Liquid-state structural asymmetry governs species-selective crystallization in multicomponent systems
Rikuya Ishikawa, Kyohei Takae, Daisuke Takegami +2
Multicomponent crystals are often assumed to form nearly random solid solutions when thermodynamically stable. However, crystal growth proceeds from structurally heterogeneous liqu…
Elastic heterogeneity governs anomalous scaling in a soft porous crystal
Kota Mitsumoto, Kyohei Takae
Nanoscale molecular transport plays a crucial role in regulating mass diffusion and responsiveness in condensed matter systems. In soft porous crystals, in particular, adsorption o…
Cooperative Ion Conduction Enabled by Site Percolation in Random Substitutional Crystals
Rikuya Ishikawa, Kyohei Takae, Rei Kurita
Efficient and safe energy storage technologies are essential for realizing a sustainable and electrified society. Among the key challenges, the design of superionic conductors for…
Spontaneous formation of Frenkel defects in high-entropy-alloys-type compound
Rikuya Ishikawa, Kyohei Takae, Yoshikazu Mizuguchi +1
High-entropy alloys (HEAs) are attracting attention due to their exceptional properties, such as enhanced mechanical toughness, superconducting robustness, and thermoelectric perfo…
Adsorption superlattice stabilized by elastic interactions in a soft porous crystal
Kota Mitsumoto, Kyohei Takae
We numerically show that molecules adsorbed in a soft porous crystal form a superlattice (SL) stabilized by elastic interactions. In a mechanically flexible honeycomb lattice model…
Diffusionless relaxation of half-skyrmion liquid, hexatic, and crystalline states in a chiral molecular crystal
Kyohei Takae, Kota Mitsumoto
Particles in a crowded environment exhibit slow anomalous diffusion, and their efficient manipulation is important in controlling transport phenomena in complex materials. Skyrmion…
