英文摘要
We studied and searched for novel quantum many-body phenomena in "4He Nanostructures", in which 4He is confined in nano-porous materials with various sizes, topological structures, and disorder. Pressure - induced quantum phase transitions (QPT) were observed, and they are related to the formation of "Localized Bose-Einstein condensates". Superfluid-like behaviors in solid 4He (supersolidity) are observed in such nanostructure systems and in thin solid 4He layer. We revealed that Helium Nanostructures are an interesting model system of "superclean Bosons", which provides "universality and emergence" in condensed matter physics.
