Extreme Nonlinear Optics in Semiconductors

Seminář / Úterý, 11.06.2019 15:00

Abstract: This talk presents an overview of our recent work on the interaction of ultrashort, high-intensity terahertz pulses with semiconductor materials. After a brief introduction to the field of extreme nonlinear optics in atoms and solids, the basic ingredients of the microscopic semiconductor modelling are summarized. Examples of successful theory-experiment comparisons are discussed, including the generation of very high harmonics, dynamical Bloch oscillations, internal quantum interference effects, quasiparticle collisions, as well as lightwave valleytronics in TMDCs...

Terahertz, Nanofabricated and Atomic Scale Probes for Density Waves Studies

Seminář / Pondělí, 10.06.2019 14:00

Abstract: Charge and spin density waves (CDW/SDW) have been a subject of condensed matter research for decades. The current interest on this topic stems in part from the CDW/SDW status in the phase diagram of superconductors, especially high Tc and related novel superconductors. Additional long term interest in these materials and states originates in their occurrence in quasi-1D and quasi-2D geometries, making their nano- and atomic scale realizations candidates for quantum materials. In this talk, we will review several approaches we have been developing since mid 2000s,...
