Abstract: While extensive work has been dedicated to the measurement of the demagnetization time following an ultra-short laser pulse, experimental studies of its underlying microscopic mechanisms are still scarce. In transition metal ferromagnets, one of the… read more here.

DOI: 10.1103/physrevb.99.085105
Abstract: We consider a short-range deformation potential scattering model of electron-acoustic phonon interaction to calculate the resistivity of an ideal metal as a function of temperature (T) and electron density (n). We consider both 3D metals… read more here.

DOI: 10.1103/physrevmaterials.3.114202
Abstract: We present optical measurements of the transition metal dichalcogenide PdTe2. The reflectivity displays an unusual temperature and energy dependence in the far infrared, which we show can only be explained by a collapse of the… read more here.

DOI: 10.1134/s002136401916001x
Abstract: We explain recent challenging experimental observations of universal scattering rate related to the linear-temperature resistivity exhibited by a large corps of both strongly correlated Fermi systems and conventional metals. We show that the observed scattering… read more here.
