Electromagnon excitations in high temperature superconducting states
Yong-Jun Chen
In this article, we discover a fundamental excitation called electromagnon in the cuprate superconducting states. Doped holes render local inversion asymmetry which produces hidden…
Roughening dynamics of spontaneous radial imbibition
Yong-Jun Chen, Kenichi Yoshikawa
We performed an experimental observation on the spontaneous imbibition of water in a porous media in a radial Hele-Shaw cell and confirmed Washburn's law, where r is distance and t…
Anomalous roughening of forced radial imbibition in a porous medium
Yong-Jun Chen, Shun Watanabe, Kenichi Yoshikawa
We report forced radial imbibition of water in a porous medium in a Hele-Shaw cell. Washburn's law is confirmed in our experiment. Radial imbibition follows scaling dynamics and sh…
Self-organized Archimedean Spiral Pattern: Regular Bundling of Fullerene through Solvent Evaporation
Yong-Jun Chen, Kosuke Suzuki, Hitoshi Mahara +2
We report the spontaneous generation of an Archimedean spiral pattern of fullerene via the evaporation of solvent. The self-organized spiral pattern exhibited equi-spacing on the o…
Quasi-logarithmic spacing law in dewetting patterns from the drying meniscus of a polymer solution
Yong-Jun Chen, Kosuke Suzuki, Hitoshi Mahara +1
We report on a periodic precipitation pattern emerged from a drying meniscus via evaporation of a polystyrene solution in a Petri dish. It appeared a quasi-logarithmic spacing rela…
Anomalous Roughening of Curvature-Driven Growth With a Variable Interface Window
Yong-Jun Chen, Yuko Nagamine, Tomohiko Yamaguchi +1
We studied the curvature-driven roughening of a disk domain pattern with a variable interface window. The relaxation of interface is driven by negative surface tension . When a dom…
