| Research Abstract |
In order to investigate the novel superfluidity of the two-dimensional (2D) registered phase of 4^He on graphite and zero-point vacancies in bosonic quantum crystals, areal density dependence and critical velocity of non-classical rotational inertia (NCRI) in 4He films adsorbed on Grafoil were performed by a torsional oscillator method. I obtained the phase diagram of 2D 4He and discovered a finite NCRI appeared in only vicinity of the registered phase.
