Ring-originated anisotropy of local structural ordering in amorphous and crystalline silicon dioxide
Motoki Shiga, Akihiko Hirata, Yohei Onodera +1
Rings comprising chemically bonded atoms are essential topological motifs for the structural ordering of network-forming materials. Quantification of such larger motifs beyond shor…
Crystal-like Order Stabilizing Glasses: Structural Origin of Ultra-stable Metallic Glasses
Zhen Lu, Anh Khoa Augustin Lu, Fan Zhang +9
Glasses are featured with a disordered amorphous structure, being opposite to crystals that are constituted by periodic lattices. In this study we report that the exceptional therm…
Crystallization behaviors in superionic conductor NaPS
Hiroshi Nakajima, Hirofumi Tsukasaki, Jiong Ding +7
All-solid-state batteries using sodium are promising candidates for next-generation rechargeable batteries due to the limited lithium resources. A practical sodium battery requires…
Metallic glasses for spintronics: anomalous temperature dependence and giant enhancement of inverse spin Hall effect
W. Jiao, D. Z. Hou, C. Chen +10
Spin-charge conversion via inverse spin Hall effect (ISHE) is essential for enabling various applications of spintronics. The spin Hall response usually follows a universal scaling…
Persistent Homology and Many-Body Atomic Structure for Medium-Range Order in the Glass
Takenobu Nakamura, Yasuaki Hiraoka, Akihiko Hirata +2
Characterization of medium-range order in amorphous materials and its relation to short-range order is discussed. A new topological approach is presented here to extract a hierarch…
Hierarchical structures of amorphous solids characterized by persistent homology
Yasuaki Hiraoka, Takenobu Nakamura, Akihiko Hirata +3
This article proposes a topological method that extracts hierarchical structures of various amorphous solids. The method is based on the persistence diagram (PD), a mathematical to…
Direct observation of high temperature superconductivity in one-unit-cell FeSe films
Wenhao Zhang, Yi Sun, Jinsong Zhang +26
Heterostructure based interface engineering has been proved an effective method for finding new superconducting systems and raising superconductivity transition temperature (TC). I…
Ultrastrong and Ultrastable Metallic Glass
Daisman P. B. Aji, Akihiko Hirata, Fan Zhu +7
The lack of thermal stability, originating from their metastable nature, has been one of the paramount obstacles that hinder the wide range of applications of metallic glasses. We…
