A Fermi disks model for the dynamical response of films of liquid 3He

We develop a model for the dynamical susceptibility of films of liquid 3He adsorbed on substrates. Although the film cannot be regarded as a two-dimensional system in coordinate space, we show that its spectrum of elementary excitations corresponds to that of a collection of two-dimensional Fermi li...
