The CECAM/Psi-k workshop: Atto2Nano: modeling ultrafast dynamics across time-scales in condensed matter took place between September 26th and September 29th, 2023 at the CECAM Headquarter at EPFL, Lausanne, Switzerland. The event attracted 37 participants from 12 countries, featuring invited talks, contributed talks, poster sessions, as well as two round-table discussions.
Overall, this workshop brought together researchers with complementary expertise in the field of experimental and theoretical ultrafast science with the goal of stimulating discussion and exchange on bridging time-scales in both ab-initio and semi-empirical approaches for non-equilibrium phenomena, focusing on time-scales ranging from attoseconds to nanoseconds. While the primary focus of the workshop was on theoretical and numerical modelling of ultrafast dynamics, our event further attracted participation of emerging and leading experimentalists from the area of time-resolved spectroscopy and microscopy.
The wide range of emergent phenomena and quasiparticles arising from excitation, correlation, and coherence of electrons, spin, photons, and nuclei provides a wealth of largely unexplored possibilities to achieve properties on demand in advanced materials. Achieving control of these phenomena constitutes the key to the formulation of novel technology concepts based on quantum materials. However, this requires a detailed understanding of light-matter coupling in many-body systems out of equilibrium via predictive ab-initio methods and semi-empirical approaches suitable to simulate time-resolved ultrafast dynamics.
Overall, this event contributed to generate an open and diverse environment that stimulated discussions and collaborations on new theoretical and computational horizons for the description of non-equilibrium dynamics and time-resolved excited-state phenomena.
