Anomalous Suppression of Superfluidity in He Confined in a Nano-porous Glass: Possible Quantum Phase Transition
K. Yamamoto, H. Nakashima, Y. Shibayama +1
We explore superfluidity for He confined in a porous glass which has nanopores of 2.5 nm in diameter, at pressures up to 5 MPa. With increasing pressure, the superfluidity is d…

Sliding Dynamics of the Wigner Crystal on Liquid He
Yoshiyuki Shibayama, Masaya Yamazaki, Hanako Isshiki +1
The Wigner crystal on liquid He accompanies with periodic corrugation of the He surface; dimples. The dynamics of the crystal is coupled with the motion and the deformation of the…
