Observation of quantum interference conductance fluctuations in metal rings with strong spin-orbit coupling
R. Ramos, T. Makiuchi, T. Kikkawa +3
We investigated the magnetotransport properties of mesoscopic platinum nanostructures (wires and rings) with sub-100 nm lateral dimensions at very low temperatures. Despite the str…
Multiple Diffusion-Freezing Mechanisms in Molecular Hydrogen Films
Takahiko Makiuchi, Katsuyuki Yamashita, Michihiro Tagai +2
Molecular hydrogen is a fascinating candidate for quantum fluid showing bosonic and fermionic superfluidity. We have studied diffusion dynamics of thin films of H, HD and D…
Elastic Anomaly of Thin Neon Film
Takahiko Makiuchi, Katsuyuki Yamashita, Michihiro Tagai +2
Adsorbed molecular films provide two-dimensional systems that show various emergent phenomena that are not observed in bulk counterparts. We have measured the elasticity of thin ne…
Elastic Anomaly of Helium Films at a Quantum Phase Transition
T. Makiuchi, M. Tagai, Y. Nago +2
Helium films show various quantum phases that undergo quantum phase transitions by changing coverage n. We found anomalous elastic phenomena in bosonic 4He and fermionic 3He films…
