Born around the turn of the new millennium, attosecond metrology has provided real-time insight into atomic-scale electron motions and light field oscillation, previously inaccessible to human observation. Until recently, this capability has relied on attosecond extreme ultraviolet pulses, generated and measured in complex vacuum systems. Next-generation attosecond metrology is now about to...

180. Ultrafast Demagnetization Probed by Attosecond Diffraction Spectroscopy

oral

Broadband attosecond pulses are employed for multimodal probing of the structural response and the magnetic order in Co-Pt magnetic multilayers following ultrafast photoexcitation observing that the onset of demagnetization is time-delayed by approximately 4 fs.

170. Transient Attosecond Soft-X-Ray Spectroscopy in Layered Semi-Metals

Dr Themistoklis Sidiropoulos (ICFO)

oral

In this work we use a high harmonic light source capable of producing single attosecond soft-xray pulses to study the ultrafast electronic and structural dynamics of layered semi-metals.

272. Role of Effective Mass in Attosecond Time-resolved Photoemission from the Non-centrosymmetric Crystal BiTeCl

S. Neb (Bielefeld University)

oral

Attosecond time-resolved photoemission experiments on the non-centrosymmetric crystal BiTeCl provide evidence that the observed dynamics of photoemission is significantly influenced by the effective electron mass in the final states.

47. Sub-cycle Quantum Electrodynamics of Strongly Laser Driven Materials

Dr Paraskevas Tzallas (Foundation for Research and Technology-Hellas, ELI-ALPS, ELI-HU Non-profit Ltd.)

03/07/2019, 12:00

oral

I will describe how the strong-field laser-matter interaction can lead to the generation of non-classical lightstates which carry the information of the ultrafast dynamics of the interaction.

264. Interface-sensitive Spectroscopy with Broadband Attosecond Pulses

Romain Geneaux (UC Berkeley)

oral

Broadband attosecond pulses are used for interface-sensitive scattering spectroscopy. Using a patterned silicon structure, the response of a 1.5 nm-thick native oxide layer is isolated. Attosecond transient reflectivity measurements are then performed on this system.
