Effects of Anomalous Andreev Reflection in High T , Layered Structures

Andreev reflection is investigated in layered anisotropic normal metal / superconductor (NE) systems in the case of an energy gap in S not negligible respect to the Fermi energy, as probably occurring in high critical temperature superconductors (HTS). We find that in these limits retroreflectivity, which is a fundamental feature of Andreev reflection, is broken modifying sensitively transport ...

Diffuse reflection of phonons and the anomalous Kapitza resistance

High-resolution time-of-flight phonon-reflection spectra in sapphire crystals are analyzed with the aid of detailed numerical calculations. It is argued that spectra from vacuum interfaces may be understood if about half the incident phonons are assumed to be reflected specularly, the remainder diffusely. A simple model of the effect on spectra of diffuse scattering is presented and compared to...

Anomalous quantum reflection of Bose-Einstein condensates from a silicon surface: the role of dynamical excitations.

We investigate the effect of interatomic interactions on the quantum-mechanical reflection of Bose-Einstein condensates from regions of rapid potential variation. The reflection process depends critically on the density and incident velocity of the condensate. For low densities and high velocities, the atom cloud has almost the same form before and after reflection. Conversely, at high densitie...

Anomalous spin-orbit torque switching due to field-like torque–assisted domain wall reflection

Spin-orbit torques (SOTs) allow the electrical control of magnetic states. Current-induced SOT switching of the perpendicular magnetization is of particular technological importance. The SOT consists of damping-like and field-like torques, and understanding the combined effects of these two torque components is required for efficient SOT switching. Previous quasi-static measurements have report...
