| Zusammenfassung: | Through the anomalous excitation spectrum in two-dimensional liquid 4He, which includes the
eects of three-phonon processes, derived in the ring-diagram approximation at low temperatures
and long wavelengths, the elementary excitation spectrum, super
uid density, thermodynamics,
structure factor, pair correlation function, phonon decay, various sounds and kinetic coecients are
reviewed and compared with experiments. KCI Citation Count: 2 |
