| Outline of Final Research Achievements |
In this project, we search for novel quantum phenomena in "Nanoscale Helium", which is realized by confining 4He in nano-spaces. We also pursuit possible applications of Nanoscale Helium by controlling superfluidity in nano-spaces. We have elucidated perfectly the mechanisms of two quantum phase transitions in 4He-nanoporous systems by dynamical measurements. We have discovered anomalous dissipation in superfluid 4He confined in regular nanopore array, and various two-dimensional solid phases in 4He immersed in graphene sheets. In application studies, we have developed superfluid Josephson junctions with flow measurement devices, and superfluid velocimeter utilizing the Doppler shift of second sound.
