“Observation of a second-sound-like mode in superfluid-filled aerogel”
Phys. Rev. Lett. 66, 1878 (1991).

液体4Heは、多孔質体中にある場合、超流動転移温度や超流動密度の抑制などのバルクの液体4Heとは異なった性質を示す。エアロジェルはSiO2によって構成された空孔率が高い多孔質体であり、構造的にやわらかいため、超流動4Heの常流動成分と結合しエアロジェルが変形することで、音波モードに第1音波と第4音波の中間のモード(Fast mode)、第2音波に似たモード(Slow mode)が存在する。当論文では、Slow modeの測定結果と両音波モードに当てはまる理論式を示す。

Prof. Germar Hoffmann

Department of Physics, National Tsing Hua University, Taiwan
“From Single Molecules to On-Surface Catalysis”

Simple Organic Molecules, albeit their structural simplicity, are a fascinating playground not only for Chemists but also for Surface Physicists.  I will present experimental results from Single-Molecule Scanning Tunneling Microscopy and Spectroscopy obtained in close collaboration with various Chemistry Groups from the study of such simple organic compounds. In these studies, which are performed on atomically flat surfaces, not only the structure but also electronic and spin properties as well as catalytic reactions are addressed. Thereby, the interaction with the surface plays a crucial role.  We will discuss the possibility to create from these molecular building blocks structurally and functionally more complex entities for molecular spintronics.
