Temperature-Squared Terms in the Heat Capacities of 3He Fluid Films

摘要: Recently the heat-capacity of a two-dimensional Fermi fluid is theoretically shown by Misawa to vary as C(T) = γ0 T - γ2 2 function temperature at low temperature, where γ 0 and are constants. To check this prediction our measured heat-capacities three different systems reexamined, i.e., first-layer second-layer 3 He films adsorbed on bare graphite surface monolayer floated 4 thin film graphite. The reproduced well predicted formula. areal-density dependence each system also coincides with Misawa's if second order perturbation treatment Fujimoto adopted self-energy calculation.
