In this talk, I will discuss how real-time spin trajectories can be used to calculate response functions beyond the conventional dynamical structure factor, focusing on thermal Hall transport and Raman circular dichroism. I will present a framework for calculating the thermal Hall conductivity from equilibrium energy-current correlations, highlighting the roles of classical statistics and nonlinear finite-temperature effects. I will then discuss how impurity-induced chiral interactions can give rise to additional Raman scattering channels. Finally, I will explore possible approaches to incorporating quantum statistics into semiclassical spin dynamics, aiming to improve dynamical response functions while preserving nonlinear real-time dynamics.\u003C\/p\u003E","summary":"","format":"limited_html"}],"field_subtitle":"","field_summary":[{"value":"\u003Cp\u003ESpecial Condensed Matter Seminar | Tuesday, October 20, 2026 \u0026nbsp;11:00am - 12:30pm | Speaker: Prof. Ignacio Salgado Linares | Host Dr. Mourigal | Howey N201\/N202\u003C\/p\u003E","format":"limited_html"}],"field_summary_sentence":[{"value":"Title: Thermal Transport and Chiral\u00a0Spectroscopy\u00a0from\u00a0Semiclassical\u00a0Spin\u00a0Dynamics.
