Attosecond pump-probe spectroscopy has opened up the possibility to study light-matter interaction with unprecedented time resolution. In this talk, I will present the results of our experiment-theory collaboration, where we apply attosecond transient absorption spectroscopy to follow the sub-laser-cycle electron dynamics of atomic xenon during strong-field tunnel ionization. The electron...

Laser pulses induce spin-selective charge flow that we show generates dramatic changes in the magnetic structure of materials, including a switching of magnetic order from anti-ferromagnetic (AFM) to transient ferromagnetic (FM) in multi-sub-lattice systems. The microscopic mechanism underpinning this ultra-fast switching of magnetic order is dominated by spin-selective charge transfer from...

The interaction of strong laser fields with matter intrinsically enables the imaging of transient dynamics with extremely high spatiotemporal resolution. This paradigm of photophysics has grown into new emerging research areas, ranging from attosecond science to laser-induced electron di diffraction, providing new insight into atoms, molecules and, more recently, condensed matter. Also, the...

Circular or highly elliptical femtosecond and attosecond pulses in the extreme ultraviolet spectral range present numerous applications in chiral-sensitive light-matter interactions1,2. Until recently, such radiation has only been available at large-scale facilities, where the time resolution is above 100 femtoseconds. Generation of coherent light sources with attosecond duration and...

When compared to atoms and solids, the collective and correlated electron dynamics in finite systems under intense light fields can be substantially modified, enhanced and controlled by plasmonic near-fields [1]. Localized near-fields result from electronic polarization and charge separation, may unfold on femtosecond or even attosecond time scales, and can have various implications on the...
