Superfluidity of He Confined in Nano-Porous Media
Keiya Shirahama, Keiichi Yamamoto, Yoshiyuki Shibayama
We have examined superfluid properties of He confined to a nano-porous Gelsil glass that has nanopores 2.5 nm in diameter. The pressure-temperature phase diagram was determined…
Thermodynamic Evidence for Nanoscale Bose-Einstein Condensation in ^4He Confined in Nanoporous Media
Keiichi Yamamoto, Yoshiyuki Shibayama, Keiya Shirahama
We report the measurements of the heat capacity of ^4He confined in nanoporous Gelsil glass that has nanopores of 2.5-nm diameter at pressures up to 5.3 MPa. The heat capacity has…
Liquid-Solid Transition and Phase Diagram of ^4He Confined in Nanoporous Glass
Keiichi Yamamoto, Yoshiyuki Shibayama, Keiya Shirahama
We have studied the liquid - solid (L-S) phase transition of ^4He confined in nanoporous glass, which has interconnected nanopores of 2.5 nm in diameter. The L-S boundary is determ…
