312. Solid State Harmonics: Spatiotemporal Properties and Connection to Band Structure

Prof. Mette B. Gaarde (Louisiana State University)

invited talks

This talk will discuss how the laser-driven electron dynamics on the band structure are imprinted on the temporal, spectral, and spatial properties of solid-state harmonics.

162. Light-Wave Magnetization Dynamics

Mr Florian Siegrist (MPI of Quantum Optics)

oral

We experimentally demonstrate direct optical control and switching of magnetization in solids with unprecedented sub-femtosecond time resolution. The reported results open the doors to a new generation of Petahertz spintronic devices.

213. Tracking the Phase Transition in VO$_2$ using High Harmonic Spectroscopy

Elissa Haddad (INRS-EMT)

oral

We investigate the dynamics of the insulator-to-metal phase transition in VO$_2$ with high temporal resolution using a new method of time-resolved high harmonic spectroscopy in a solid-state system, revealing all electronic states involved.

262. Reconstruction of Valence Electron Density in Solids using Optical Laser Fields

Harshit Lakhotia (University of Rostock)

04/07/2019, 09:30

oral

In this work, we show that the high harmonic generation in solids in the presence of intense optical laser fields allows us to visualize valence electrons with a sub-Angstrom resolution for the first time.

247. Multi-Band Petahertz Currents Resolved via High Harmonic Generation Spectroscopy

Ayelet Uzan (Weizmann Institute of Science)

04/07/2019, 09:45

oral

In our study we reveal the underlying attosecond dynamics that dictates the temporal evolution of carriers in multi-band solid state systems, via high harmonic generation (HHG) spectroscopy.

219. Ultrafast Spin Dynamics and High Harmonic Generation in 2D Systems

Dominik Schulze (Martin-Luther-Universität Halle-Wittenberg)

04/07/2019, 10:00

oral

In this talk, we present our research on high-harmonic generation in systems with strong spin-orbit coupling such as multilayer systems based on graphene and transition metal dichalcogenides.
