Next April, the 4th conference on Advances in Ultrafast Condensed Phase Physics will take place in the framework of SPIE Photonics Europe (April 7-11 2024) in Strasbourg, France. We hope to cover and learn about novel results and the state of the art in strong-field processes, high-harmonic generation, ultrafast electron dynamics, magnetism, phase transitions, and non-adiabatic dynamics in simple and complex solids. We would be delighted to meet you in Strasbourg, please consider submitting your 250-word abstract by November 30, 2023 at [www.spie.org/pe103call]
