In quantum materials, emergent functional properties resulting from strong correlations or
electronic topology offer opportunities for new applications. Over the past decade, ultrafast …

Key properties of quantum materials stem from dynamic interaction chains that connect
stable electronic quasiparticles through short-lived coherences, which are difficult to control …

Magnetic phenomena are ubiquitous in nature and indispensable for modern science and
technology, but it is notoriously difficult to change the magnetic order of a material in a rapid …

Since the first demonstration of the generation of attosecond pulses (1 as= 10− 18 s) in the
extreme-ultraviolet spectral region, several measurement techniques have been introduced …

Delocalized Bloch electrons and the low-energy correlations between them determine key
