Acoustic waves in crystals: I. Ultrasonic flux imaging and internal diffraction. II. Imaging phonons in superconducting niobium
Abstract
dc:descriptionAcoustic wave propagation is studied via imaging techniques in two regimes not previously amenable to such experiments. (I) The low-temperature phonon-imaging technique is extended to ultrasonic frequencies at room temperatures where it is used to study the anisotropic propagation of acoustic waves in crystals. (II) The low-temperature heat-pulse technique is applied to a study of phonon transport in superconducting niobium, providing the first phonon images of a metal and revealing interesting interactions between phonons and quasiparticles.
