One of the central themes of the TIMES Workshop Frontiers in Ultrafast Phenomena in Quantum Materials, held in Frascati, Italy, was the investigation of excitonic phenomena and ultrafast light–matter interactions in emerging quantum materials.
Throughout the meeting, researchers presented recent theoretical and experimental advances addressing the behaviour of excitons in low-dimensional systems, including transition metal dichalcogenides, van der Waals heterostructures and topological materials. Several contributions focused on the microscopic description of exciton formation, transport and relaxation processes, which are essential for future optoelectronic and quantum technologies.
The programme featured discussions on excitonic populations beyond the dilute limit, ultrafast exciton correlations, valley dynamics in two-dimensional materials and the role of exciton–phonon interactions in determining coherence and transport properties. Other presentations explored how attosecond spectroscopy and advanced ultrafast probes can reveal the electronic structure and topological properties of quantum materials under non-equilibrium conditions.
A recurring message throughout the workshop was the increasing convergence between advanced computational methods and cutting-edge experimental techniques. This synergy is enabling unprecedented insight into the ultrafast processes that govern the behaviour of quantum materials and is opening new opportunities for designing materials with tailored optical and electronic properties.
The scientific discussions held during the workshop demonstrated the vitality of this research area and reinforced the importance of interdisciplinary collaboration in addressing some of the most challenging questions in contemporary condensed matter physics.
