Excitation spectrum in two-dimensional superfluid ⁴He
In this work we perform an ab-initio study of an ideal two-dimensional sample of ⁴He atoms, a model for ⁴He films adsorbed on several kinds of substrates. Starting from a realistic hamiltonian we face the microscopic study of the excitation phonon–roton spectrum of the system at zero temperature...
