Possible quantum liquid crystal phases of helium monolayers
S. Nakamura, K. Matsui, T. Matsui +1
The second-layer phase diagrams of He and He adsorbed on graphite are investigated. Intrinsically rounded specific-heat anomalies are observed at 1.4 and 0.9 K, respectivel…
Millikelvin LEED apparatus: a feasibility study
K. Matsui, S. Nakamura, T. Matsui +1
A low-energy electron diffraction (LEED) apparatus which works at temperatures down to about 100 mK is designed to obtain structural information of 2D helium on graphite. This very…
New Heat-Capacity Measurements of the Possible Order-Disorder Transition in the 4/7-phase of 2D Helium
S. Nakamura, K. Matsui, T. Matsui +1
We have developed a new heat-capacity measuring system with ZYX graphite that is known to have much better crystallinity than Grafoil and started data collection. We report prelimi…
Preliminary Heat Capacity and Vapor Pressure Measurements of 2D 4He on ZYX Graphite
S. Nakamura, K. Matsui, T. Matsui +1
We report preliminary heat capacity and vapor pressure measurements of the first and second layers of 4He adsorbed on ZYX graphite. ZYX is known to have much better crystallinity t…
