TT 34: Focus Session: Dynamical Probes for Topological Magnetism

Mittwoch, 20. März 2024, 09:30–12:15, H 0104

Non-equilibrium phenomena are attracting a great deal of interest. One of the main reasons for this intense research effort is to establish the coherent control of quantum states. Magnetic systems constitute promising platforms in this respect because they display quantum properties already in the groundstate. Moreover, several manifestation of coherent spin dynamics in a wide variety of materials and in different regimes (linear, nonlinear, transport, THz frequencies) have been reported. Topological protection of their quantum states adds to the advantageous properties. In view of these aspects, the proposed focus session is intended to present experimental and theoretical advances ranging from ab initio calculations over model simulations to experiments demonstrating the generation, control and detection of spin dynamics.
