Non-thermal transport of energy driven by photoexcited carriers in switchable solid states of GeTe
R. Gu, T. Perrault, V. Juvé +10
Phase change alloys have seen widespread use from rewritable optical discs to the present day interest in their use in emerging neuromorphic computing architectures. In spite of th…
Transversal-rotational and zero group velocity modes in tunable magneto-granular phononic crystals
F. Allein, V. Tournat, V. E. Gusev +1
We report on the design and operation of a 1D magneto-granular phononic crystal composed of a chain of steel spherical beads on top of permanent magnets. The magnetic field of the…
Tunable magneto-granular phononic crystals
F. Allein, V. Tournat, V. E. Gusev +1
This paper reports on the study of the dynamics of 1D magneto-granular phononic crystals composed of a chain of spherical steel beads inside a properly designed magnetic field. Thi…
Ultrafast electron-phonon-magnon interactions at noble metal-ferromagnet interfaces
V. Shalagatskyi, O. Kovalenko, V. Shumylo +8
Ultrafast optical excitation of gold-cobalt bilayers triggers the nontrivial interplay between the electronic, acoustic, and magnetic degrees of freedom. Laser-heated electrons gen…
Surface waves in granular phononic crystals
Helene Pichard, Aroune Duclos, Jean-Philippe Groby +3
The existence of surface elastic waves at a mechanically free surface of granular phononic crystals is studied. The granular phononic crystals are made of spherical particles distr…
Nonlinear Hysteretic Torsional Waves
J. Cabaret, P. Béquin, G. Theocharis +3
We theoretically study and experimentally report the propagation of nonlinear hysteretic torsional pulses in a vertical granular chain made of cm-scale, self-hanged magnetic beads.…
