متن کاملGiant anharmonic phonon scattering in PbTe.
Understanding the microscopic processes affecting the bulk thermal conductivity is crucial to develop more efficient thermoelectric materials. PbTe is currently one of the leading thermoelectric materials, largely thanks to its low thermal conductivity. However, the origin of this low thermal conductivity in a simple rocksalt structure has so far been elusive. Using a combination of inelastic n...
متن کاملAnharmonic phonon excitations in subbarrier fusion reactions
Recently measured high precision data of fusion excitation function have enabled a detailed study on the e ects of nuclear collective excitations on fusion reactions. Using such highly accurate data of the O + Sm reactions, we discuss the anharmonic properties of collective phonon excitations in Sm nuclei. It is shown that subbarrier fusion reactions are strongly a ected by the anharmonic e ect...

متن کاملAnharmonic Frequency Analysis
A new numerical method of frequency analysis is described, designed mainly to search for discrete frequencies in a time series. An integral transform is applied twice to the data for different reference times. A complex amplitude within a selected narrow frequency band is obtained for each transform. The frequency is then determined from the phase change of the complex amplitude over the differ...
