Spin-density fluctuations and the fluctuation-dissipation theorem in 3d ferromagnetic metals
A. L. Wysocki, V. N. Valmispild, A. Kutepov +5
Spatial and time scales of spin density fluctuations (SDF) were analyzed in 3d ferromagnets using ab initio linear response calculations of complete wavevector and energy dependenc…
Role of Spin Flips versus Spin Transport in Non Thermal Electrons Excited by Ultrashort Optical Pulses in Transition Metals
V. Shokeen, M. Sanchez Piaia, J. -Y. Bigot +5
A joint theoretical and experimental investigation is performed to understand the underlying physics of laser-induced demagnetization in Ni and Co films. Experimentally dynamics of…
Bulk physics entwined with a topological surface state
N. Klier, S. Sharma, O. Pankratov +1
For the IV-VI semiconductor family we derive an exact relation between the microscopic gap edge wave functions of the bulk insulator and the Dirac-Weyl topological surface state wa…
