At 10:00 a.m. on December 30, 2019, Professor Branislav K. Nikolić visited UESTC and gave a presentation in Conference Room 137 of ESE, Shahe campus. He introduced recent advances in Multiscale time-dependent-quantum-transport/Classical-micromagnetics approach to dynamics of noncollinear magnetic textures.

Multiscale and self-consistent computational combines time-dependent nonequilibrium Green function (TDNEGF) algorithms, scales linearly in the number of time steps and describes quantum-mechanically conduction electrons in the presence of time-dependent fields of arbitrary strength or frequency, with classical description of the dynamics of local magnetic moments based on the Landau-Lifshitz-Gilbert (LLG) equation. Such TDNEGF+LLG approach can be applied to a variety of problems where current-driven spin torque induces the dynamics of magnetic moments as the key resource for next generation spintronics.
