Light-Driven Control of Quantum Antiferromagnets: Recent Experiments and Future Prospects
Dr Flavio Giorgianni, University of Bern – Institute of Applied Physics, and Paul Scherrer Institut

Abstract:
The control of quantum materials with tailored light fields opens new avenues for manipulating collective excitations and out-of-equilibrium phases of matter. In this talk, I will first discuss recent advances in shaping the polarization of high-field terahertz pulses to selectively drive infrared-active phonons, providing new routes to control material responses with high precision. Building on this perspective, I will then present our recent ultrafast experiments on quantum antiferromagnets, where light can efficiently modulate exchange interactions and induce coherent spin dynamics. Finally, I will outline future prospects for experiments aimed at actively engineering and potentially stabilizing novel quantum states in correlated spin systems.
