Exploring the Nonlinear Magnetic Response of FeI₂ via Two-Dimensional Coherent Spectroscopy
Nonlinear THz spectroscopy has emerged as a powerful method to extract new
information beyond conventional linear response. In this work, we employ a
semi-classical approach to 2-dimensional coherent spectroscopy (2DCS),
implemented in the context of the Sunny Julia package for modelling atomic-scale
magnetism. We apply this framework to explore the nonlinear response of FeI₂,
a 2D spin-1 antiferromagnet with hybridized dipolar-quadrupolar fluctuations,
to reveal its rich nonlinear dynamics.
