Abstract

We report clear experimental signatures of the theoretically unexpected gas-liquid transition in the first three monolayer systems of He3 adsorbed on graphite. The transition is inferred from the linear density dependence of the gamma coefficient of the heat capacity measured in the degenerate region (2T80mK) below a critical liquid density (ρc0). Surprisingly, the measured ρc0 values (0.60.9nm2) are nearly the same for all these layers in spite of their quite different environments. We conclude that the ground state of He3 in strictly two dimensions is not a dilute quantum gas but a self-bound quantum liquid with the lowest density ever found.

Helium Puddles Near Absolute Zero

Published 3 December 2012

Measurements of the heat capacity in two-dimensional helium-3 adsorbed on graphite provide further evidence of an unexpected liquid state at temperatures near absolute zero.
