Lattice thermal conductivity in the anharmonic overdamped regime
Đorđe Dangić, Giovanni Caldarelli, Raffaello Bianco +2
In crystalline materials, low lattice thermal conductivity is often associated with strong anharmonicity, which can cause significant deviations from the expected Lorentzian linesh…

Evolution of non-thermal phonon and electron populations in photo-excited germanium on picosecond timescales
F. Murphy-Armando, É. D. Murray, I. Savić +3
We investigate from first-principles theory and experiment the generation of phonons on picosecond timescales and the relaxation of carriers in multiple conduction band valleys of…
