A model calculation is presented for the heat transport across an extended atomic well boundary separating two ultrathin solid films, due to the phonons coherent elastic scattering at the boundary. Using the matching method, the transmission spectra are calculated for the phonons coherent...

A theoretical model is presented for the study of the scattering of phonons at an extended inhomogeneous boundary separating thin solid monatomic films. The model system consists of two solid films with otherwise stress-free surfaces on either side of an atomic well boundary. The coherent...

The phase diagram and paramagnetic susceptibility of the spin 32 Blume-Capel model are investigated within the statistical accuracy of the Bethe-Peierls approximation (or the correlated effective field treatment). In particular, the inverse paramagnetic susceptibility may show an outstanding...

The vibrational properties of the three ordered metallic surface alloys, Cu(100)-c(2 × 2)-Pd, Cu(100)-(2 × 1)-Pd, and Cu(100)-(2 × 2)-Pd, are presented. The phonon dispersions of vibrational modes as well as the local density of phonon states (LDOS) are calculated using matching theory...

A theoretical model is presented for the study of the scattering of magnons at an extended symmetric atomic well in very thin magnetic films. The thin film consists of three cubic atomic planes with ordered spins coupled by Heisenberg exchange, and the system is supported on a non-magnetic...
